+
+0.9.0
+~~~~~
+First version.
+
+
+0.9.0a
+~~~~~~
+Removed 'ranlib' from Makefile, since most modern Unix-es
+don't need it, or even know about it.
+
+
+0.9.0b
+~~~~~~
+Fixed a problem with error reporting in bzip2.c. This does not effect
+the library in any way. Problem is: versions 0.9.0 and 0.9.0a (of the
+program proper) compress and decompress correctly, but give misleading
+error messages (internal panics) when an I/O error occurs, instead of
+reporting the problem correctly. This shouldn't give any data loss
+(as far as I can see), but is confusing.
+
+Made the inline declarations disappear for non-GCC compilers.
+
+
+0.9.0c
+~~~~~~
+Fixed some problems in the library pertaining to some boundary cases.
+This makes the library behave more correctly in those situations. The
+fixes apply only to features (calls and parameters) not used by
+bzip2.c, so the non-fixedness of them in previous versions has no
+effect on reliability of bzip2.c.
+
+In bzlib.c:
+ * made zero-length BZ_FLUSH work correctly in bzCompress().
+ * fixed bzWrite/bzRead to ignore zero-length requests.
+ * fixed bzread to correctly handle read requests after EOF.
+ * wrong parameter order in call to bzDecompressInit in
+ bzBuffToBuffDecompress. Fixed.
+
+In compress.c:
+ * changed setting of nGroups in sendMTFValues() so as to
+ do a bit better on small files. This _does_ effect
+ bzip2.c.
+
+
+0.9.5a
+~~~~~~
+Major change: add a fallback sorting algorithm (blocksort.c)
+to give reasonable behaviour even for very repetitive inputs.
+Nuked --repetitive-best and --repetitive-fast since they are
+no longer useful.
+
+Minor changes: mostly a whole bunch of small changes/
+bugfixes in the driver (bzip2.c). Changes pertaining to the
+user interface are:
+
+ allow decompression of symlink'd files to stdout
+ decompress/test files even without .bz2 extension
+ give more accurate error messages for I/O errors
+ when compressing/decompressing to stdout, don't catch control-C
+ read flags from BZIP2 and BZIP environment variables
+ decline to break hard links to a file unless forced with -f
+ allow -c flag even with no filenames
+ preserve file ownerships as far as possible
+ make -s -1 give the expected block size (100k)
+ add a flag -q --quiet to suppress nonessential warnings
+ stop decoding flags after --, so files beginning in - can be handled
+ resolved inconsistent naming: bzcat or bz2cat ?
+ bzip2 --help now returns 0
+
+Programming-level changes are:
+
+ fixed syntax error in GET_LL4 for Borland C++ 5.02
+ let bzBuffToBuffDecompress return BZ_DATA_ERROR{_MAGIC}
+ fix overshoot of mode-string end in bzopen_or_bzdopen
+ wrapped bzlib.h in #ifdef __cplusplus ... extern "C" { ... }
+ close file handles under all error conditions
+ added minor mods so it compiles with DJGPP out of the box
+ fixed Makefile so it doesn't give problems with BSD make
+ fix uninitialised memory reads in dlltest.c
+
+0.9.5b
+~~~~~~
+Open stdin/stdout in binary mode for DJGPP.
+
+0.9.5c
+~~~~~~
+Changed BZ_N_OVERSHOOT to be ... + 2 instead of ... + 1. The + 1
+version could cause the sorted order to be wrong in some extremely
+obscure cases. Also changed setting of quadrant in blocksort.c.
+
+0.9.5d
+~~~~~~
+The only functional change is to make bzlibVersion() in the library
+return the correct string. This has no effect whatsoever on the
+functioning of the bzip2 program or library. Added a couple of casts
+so the library compiles without warnings at level 3 in MS Visual
+Studio 6.0. Included a Y2K statement in the file Y2K_INFO. All other
+changes are minor documentation changes.
+
+1.0
+~~~
+Several minor bugfixes and enhancements:
+
+* Large file support. The library uses 64-bit counters to
+ count the volume of data passing through it. bzip2.c
+ is now compiled with -D_FILE_OFFSET_BITS=64 to get large
+ file support from the C library. -v correctly prints out
+ file sizes greater than 4 gigabytes. All these changes have
+ been made without assuming a 64-bit platform or a C compiler
+ which supports 64-bit ints, so, except for the C library
+ aspect, they are fully portable.
+
+* Decompression robustness. The library/program should be
+ robust to any corruption of compressed data, detecting and
+ handling _all_ corruption, instead of merely relying on
+ the CRCs. What this means is that the program should
+ never crash, given corrupted data, and the library should
+ always return BZ_DATA_ERROR.
+
+* Fixed an obscure race-condition bug only ever observed on
+ Solaris, in which, if you were very unlucky and issued
+ control-C at exactly the wrong time, both input and output
+ files would be deleted.
+
+* Don't run out of file handles on test/decompression when
+ large numbers of files have invalid magic numbers.
+
+* Avoid library namespace pollution. Prefix all exported
+ symbols with BZ2_.
+
+* Minor sorting enhancements from my DCC2000 paper.
+
+* Advance the version number to 1.0, so as to counteract the
+ (false-in-this-case) impression some people have that programs
+ with version numbers less than 1.0 are in someway, experimental,
+ pre-release versions.
+
+* Create an initial Makefile-libbz2_so to build a shared library.
+ Yes, I know I should really use libtool et al ...
+
+* Make the program exit with 2 instead of 0 when decompression
+ fails due to a bad magic number (ie, an invalid bzip2 header).
+ Also exit with 1 (as the manual claims :-) whenever a diagnostic
+ message would have been printed AND the corresponding operation
+ is aborted, for example
+ bzip2: Output file xx already exists.
+ When a diagnostic message is printed but the operation is not
+ aborted, for example
+ bzip2: Can't guess original name for wurble -- using wurble.out
+ then the exit value 0 is returned, unless some other problem is
+ also detected.
+
+ I think it corresponds more closely to what the manual claims now.
+
+
+1.0.1
+~~~~~
+* Modified dlltest.c so it uses the new BZ2_ naming scheme.
+* Modified makefile-msc to fix minor build probs on Win2k.
+* Updated README.COMPILATION.PROBLEMS.
+
+There are no functionality changes or bug fixes relative to version
+1.0.0. This is just a documentation update + a fix for minor Win32
+build problems. For almost everyone, upgrading from 1.0.0 to 1.0.1 is
+utterly pointless. Don't bother.

+This is the README for bzip2, a block-sorting file compressor, version
+1.0. This version is fully compatible with the previous public
+releases, bzip2-0.1pl2, bzip2-0.9.0 and bzip2-0.9.5.
+
+bzip2-1.0 is distributed under a BSD-style license. For details,
+see the file LICENSE.
+
+Complete documentation is available in Postscript form (manual.ps) or
+html (manual_toc.html). A plain-text version of the manual page is
+available as bzip2.txt. A statement about Y2K issues is now included
+in the file Y2K_INFO.
+
+
+HOW TO BUILD -- UNIX
+
+Type `make'. This builds the library libbz2.a and then the
+programs bzip2 and bzip2recover. Six self-tests are run.
+If the self-tests complete ok, carry on to installation:
+
+To install in /usr/bin, /usr/lib, /usr/man and /usr/include, type
+ make install
+To install somewhere else, eg, /xxx/yyy/{bin,lib,man,include}, type
+ make install PREFIX=/xxx/yyy
+If you are (justifiably) paranoid and want to see what 'make install'
+is going to do, you can first do
+ make -n install or
+ make -n install PREFIX=/xxx/yyy respectively.
+The -n instructs make to show the commands it would execute, but
+not actually execute them.
+
+
+HOW TO BUILD -- UNIX, shared library libbz2.so.
+
+Do 'make -f Makefile-libbz2_so'. This Makefile seems to work for
+Linux-ELF (RedHat 5.2 on an x86 box), with gcc. I make no claims
+that it works for any other platform, though I suspect it probably
+will work for most platforms employing both ELF and gcc.
+
+bzip2-shared, a client of the shared library, is also build, but
+not self-tested. So I suggest you also build using the normal
+Makefile, since that conducts a self-test.
+
+Important note for people upgrading .so's from 0.9.0/0.9.5 to
+version 1.0. All the functions in the library have been renamed,
+from (eg) bzCompress to BZ2_bzCompress, to avoid namespace pollution.
+Unfortunately this means that the libbz2.so created by
+Makefile-libbz2_so will not work with any program which used an
+older version of the library. Sorry. I do encourage library
+clients to make the effort to upgrade to use version 1.0, since
+it is both faster and more robust than previous versions.
+
+
+HOW TO BUILD -- Windows 95, NT, DOS, Mac, etc.
+
+It's difficult for me to support compilation on all these platforms.
+My approach is to collect binaries for these platforms, and put them
+on the master web page (http://sourceware.cygnus.com/bzip2). Look
+there. However (FWIW), bzip2-1.0 is very standard ANSI C and should
+compile unmodified with MS Visual C. For Win32, there is one
+important caveat: in bzip2.c, you must set BZ_UNIX to 0 and
+BZ_LCCWIN32 to 1 before building. If you have difficulties building,
+you might want to read README.COMPILATION.PROBLEMS.
+
+
+VALIDATION
+
+Correct operation, in the sense that a compressed file can always be
+decompressed to reproduce the original, is obviously of paramount
+importance. To validate bzip2, I used a modified version of Mark
+Nelson's churn program. Churn is an automated test driver which
+recursively traverses a directory structure, using bzip2 to compress
+and then decompress each file it encounters, and checking that the
+decompressed data is the same as the original. There are more details
+in Section 4 of the user guide.
+
+
+
+Please read and be aware of the following:
+
+WARNING:
+
+ This program (attempts to) compress data by performing several
+ non-trivial transformations on it. Unless you are 100% familiar
+ with *all* the algorithms contained herein, and with the
+ consequences of modifying them, you should NOT meddle with the
+ compression or decompression machinery. Incorrect changes can and
+ very likely *will* lead to disastrous loss of data.
+
+
+DISCLAIMER:
+
+ I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
+ USE OF THIS PROGRAM, HOWSOEVER CAUSED.
+
+ Every compression of a file implies an assumption that the
+ compressed file can be decompressed to reproduce the original.
+ Great efforts in design, coding and testing have been made to
+ ensure that this program works correctly. However, the complexity
+ of the algorithms, and, in particular, the presence of various
+ special cases in the code which occur with very low but non-zero
+ probability make it impossible to rule out the possibility of bugs
+ remaining in the program. DO NOT COMPRESS ANY DATA WITH THIS
+ PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE POSSIBILITY, HOWEVER
+ SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.
+
+ That is not to say this program is inherently unreliable. Indeed,
+ I very much hope the opposite is true. bzip2 has been carefully
+ constructed and extensively tested.
+
+
+PATENTS:
+
+ To the best of my knowledge, bzip2 does not use any patented
+ algorithms. However, I do not have the resources available to
+ carry out a full patent search. Therefore I cannot give any
+ guarantee of the above statement.
+
+End of legalities.
+
+
+WHAT'S NEW IN 0.9.0 (as compared to 0.1pl2) ?
+
+ * Approx 10% faster compression, 30% faster decompression
+ * -t (test mode) is a lot quicker
+ * Can decompress concatenated compressed files
+ * Programming interface, so programs can directly read/write .bz2 files
+ * Less restrictive (BSD-style) licensing
+ * Flag handling more compatible with GNU gzip
+ * Much more documentation, i.e., a proper user manual
+ * Hopefully, improved portability (at least of the library)
+
+WHAT'S NEW IN 0.9.5 ?
+
+ * Compression speed is much less sensitive to the input
+ data than in previous versions. Specifically, the very
+ slow performance caused by repetitive data is fixed.
+ * Many small improvements in file and flag handling.
+ * A Y2K statement.
+
+WHAT'S NEW IN 1.0
+
+ See the CHANGES file.
+
+I hope you find bzip2 useful. Feel free to contact me at
+ jseward@acm.org
+if you have any suggestions or queries. Many people mailed me with
+comments, suggestions and patches after the releases of bzip-0.15,
+bzip-0.21, bzip2-0.1pl2 and bzip2-0.9.0, and the changes in bzip2 are
+largely a result of this feedback. I thank you for your comments.

+bzip2-1.0 should compile without problems on the vast majority of
+platforms. Using the supplied Makefile, I've built and tested it
+myself for x86-linux, sparc-solaris, alpha-linux, x86-cygwin32 and
+alpha-tru64unix. With makefile.msc, Visual C++ 6.0 and nmake, you can
+build a native Win32 version too. Large file support seems to work
+correctly on at least alpha-tru64unix and x86-cygwin32 (on Windows
+2000).
+
+When I say "large file" I mean a file of size 2,147,483,648 (2^31)
+bytes or above. Many older OSs can't handle files above this size,
+but many newer ones can. Large files are pretty huge -- most files
+you'll encounter are not Large Files.
+
+Earlier versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide
+variety of platforms without difficulty, and I hope this version will
+continue in that tradition. However, in order to support large files,
+I've had to include the define -D_FILE_OFFSET_BITS=64 in the Makefile.
+This can cause problems.
+
+The technique of adding -D_FILE_OFFSET_BITS=64 to get large file
+support is, as far as I know, the Recommended Way to get correct large
+file support. For more details, see the Large File Support
+Specification, published by the Large File Summit, at
+ http://www.sas.com/standard/large.file/
+
+As a general comment, if you get compilation errors which you think
+are related to large file support, try removing the above define from
+the Makefile, ie, delete the line
+ BIGFILES=-D_FILE_OFFSET_BITS=64
+from the Makefile, and do 'make clean ; make'. This will give you a
+version of bzip2 without large file support, which, for most
+applications, is probably not a problem.
+
+Alternatively, try some of the platform-specific hints listed below.
+
+You can use the spewG.c program to generate huge files to test bzip2's
+large file support, if you are feeling paranoid. Be aware though that
+any compilation problems which affect bzip2 will also affect spewG.c,
+alas.
+
+
+Known problems as of 1.0pre8:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* HP/UX 10.20 and 11.00, using gcc (2.7.2.3 and 2.95.2): A large
+ number of warnings appear, including the following:
+
+ /usr/include/sys/resource.h: In function `getrlimit':
+ /usr/include/sys/resource.h:168:
+ warning: implicit declaration of function `__getrlimit64'
+ /usr/include/sys/resource.h: In function `setrlimit':
+ /usr/include/sys/resource.h:170:
+ warning: implicit declaration of function `__setrlimit64'
+
+ This would appear to be a problem with large file support, header
+ files and gcc. gcc may or may not give up at this point. If it
+ fails, you might be able to improve matters by adding
+ -D__STDC_EXT__=1
+ to the BIGFILES variable in the Makefile (ie, change its definition
+ to
+ BIGFILES=-D_FILE_OFFSET_BITS=64 -D__STDC_EXT__=1
+
+ Even if gcc does produce a binary which appears to work (ie passes
+ its self-tests), you might want to test it to see if it works properly
+ on large files.
+
+
+* HP/UX 10.20 and 11.00, using HP's cc compiler.
+
+ No specific problems for this combination, except that you'll need to
+ specify the -Ae flag, and zap the gcc-specific stuff
+ -Wall -Winline -O2 -fomit-frame-pointer -fno-strength-reduce.
+ You should retain -D_FILE_OFFSET_BITS=64 in order to get large
+ file support -- which is reported to work ok for this HP/UX + cc
+ combination.
+
+
+* SunOS 4.1.X.
+
+ Amazingly, there are still people out there using this venerable old
+ banger. I shouldn't be too rude -- I started life on SunOS, and
+ it was a pretty darn good OS, way back then. Anyway:
+
+ SunOS doesn't seem to have strerror(), so you'll have to use
+ perror(), perhaps by doing adding this (warning: UNTESTED CODE):
+
+ char* strerror ( int errnum )
+ {
+ if (errnum < 0 || errnum >= sys_nerr)
+ return "Unknown error";
+ else
+ return sys_errlist[errnum];
+ }
+
+ Or you could comment out the relevant calls to strerror; they're
+ not mission-critical. Or you could upgrade to Solaris. Ha ha ha!
+ (what?? you think I've got Bad Attitude?)
+
+
+* Making a shared library on Solaris. (Not really a compilation
+ problem, but many people ask ...)
+
+ Firstly, if you have Solaris 8, either you have libbz2.so already
+ on your system, or you can install it from the Solaris CD.
+
+ Secondly, be aware that there are potential naming conflicts
+ between the .so file supplied with Solaris 8, and the .so file
+ which Makefile-libbz2_so will make. Makefile-libbz2_so creates
+ a .so which has the names which I intend to be "official" as
+ of version 1.0.0 and onwards. Unfortunately, the .so in
+ Solaris 8 appeared before I decided on the final names, so
+ the two libraries are incompatible. We have since communicated
+ and I hope that the problems will have been solved in the next
+ version of Solaris, whenever that might appear.
+
+ All that said: you might be able to get somewhere
+ by finding the line in Makefile-libbz2_so which says
+
+ $(CC) -shared -Wl,-soname -Wl,libbz2.so.1.0 -o libbz2.so.1.0.1 $(OBJS)
+
+ and replacing with
+
+ ($CC) -G -shared -o libbz2.so.1.0.1 -h libbz2.so.1.0 $(OBJS)
+
+ If gcc objects to the combination -fpic -fPIC, get rid of
+ the second one, leaving just "-fpic".
+
+
+That's the end of the currently known compilation problems.

+
+Y2K status of bzip2 and libbzip2, versions 0.1, 0.9.0 and 0.9.5
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Informally speaking:
+ bzip2 is a compression program built on top of libbzip2,
+ a library which does the real work of compression and
+ decompression. As far as I am aware, libbzip2 does not have
+ any date-related code at all.
+
+ bzip2 itself copies dates from source to destination files
+ when compressing or decompressing, using the 'stat' and 'utime'
+ UNIX system calls. It doesn't examine, manipulate or store the
+ dates in any way. So as far as I can see, there shouldn't be any
+ problem with bzip2 providing 'stat' and 'utime' work correctly
+ on your system.
+
+ On non-unix platforms (those for which BZ_UNIX in bzip2.c is
+ not set to 1), bzip2 doesn't even do the date copying.
+
+ Overall, informally speaking, I don't think bzip2 or libbzip2
+ have a Y2K problem.
+
+Formally speaking:
+ I am not prepared to offer you any assurance whatsoever
+ regarding Y2K issues in my software. You alone assume the
+ entire risk of using the software. The disclaimer of liability
+ in the LICENSE file in the bzip2 source distribution continues
+ to apply on this issue as with every other issue pertaining
+ to the software.

+
+.SH DESCRIPTION
+.I bzip2
+compresses files using the Burrows-Wheeler block sorting
+text compression algorithm, and Huffman coding. Compression is
+generally considerably better than that achieved by more conventional
+LZ77/LZ78-based compressors, and approaches the performance of the PPM
+family of statistical compressors.
+
+The command-line options are deliberately very similar to
+those of
+.I GNU gzip,
+but they are not identical.
+
+.I bzip2
+expects a list of file names to accompany the
+command-line flags. Each file is replaced by a compressed version of
+itself, with the name "original_name.bz2".
+Each compressed file
+has the same modification date, permissions, and, when possible,
+ownership as the corresponding original, so that these properties can
+be correctly restored at decompression time. File name handling is
+naive in the sense that there is no mechanism for preserving original
+file names, permissions, ownerships or dates in filesystems which lack
+these concepts, or have serious file name length restrictions, such as
+MS-DOS.
+
+.I bzip2
+and
+.I bunzip2
+will by default not overwrite existing
+files. If you want this to happen, specify the \-f flag.
+
+If no file names are specified,
+.I bzip2
+compresses from standard
+input to standard output. In this case,
+.I bzip2
+will decline to
+write compressed output to a terminal, as this would be entirely
+incomprehensible and therefore pointless.
+
+.I bunzip2
+(or
+.I bzip2 \-d)
+decompresses all
+specified files. Files which were not created by
+.I bzip2
+will be detected and ignored, and a warning issued.
+.I bzip2
+attempts to guess the filename for the decompressed file
+from that of the compressed file as follows:
+
+ filename.bz2 becomes filename
+ filename.bz becomes filename
+ filename.tbz2 becomes filename.tar
+ filename.tbz becomes filename.tar
+ anyothername becomes anyothername.out
+
+If the file does not end in one of the recognised endings,
+.I .bz2,
+.I .bz,
+.I .tbz2
+or
+.I .tbz,
+.I bzip2
+complains that it cannot
+guess the name of the original file, and uses the original name
+with
+.I .out
+appended.
+
+As with compression, supplying no
+filenames causes decompression from
+standard input to standard output.
+
+.I bunzip2
+will correctly decompress a file which is the
+concatenation of two or more compressed files. The result is the
+concatenation of the corresponding uncompressed files. Integrity
+testing (\-t)
+of concatenated
+compressed files is also supported.
+
+You can also compress or decompress files to the standard output by
+giving the \-c flag. Multiple files may be compressed and
+decompressed like this. The resulting outputs are fed sequentially to
+stdout. Compression of multiple files
+in this manner generates a stream
+containing multiple compressed file representations. Such a stream
+can be decompressed correctly only by
+.I bzip2
+version 0.9.0 or
+later. Earlier versions of
+.I bzip2
+will stop after decompressing
+the first file in the stream.
+
+.I bzcat
+(or
+.I bzip2 -dc)
+decompresses all specified files to
+the standard output.
+
+.I bzip2
+will read arguments from the environment variables
+.I BZIP2
+and
+.I BZIP,
+in that order, and will process them
+before any arguments read from the command line. This gives a
+convenient way to supply default arguments.
+
+Compression is always performed, even if the compressed
+file is slightly
+larger than the original. Files of less than about one hundred bytes
+tend to get larger, since the compression mechanism has a constant
+overhead in the region of 50 bytes. Random data (including the output
+of most file compressors) is coded at about 8.05 bits per byte, giving
+an expansion of around 0.5%.
+
+As a self-check for your protection,
+.I
+bzip2
+uses 32-bit CRCs to
+make sure that the decompressed version of a file is identical to the
+original. This guards against corruption of the compressed data, and
+against undetected bugs in
+.I bzip2
+(hopefully very unlikely). The
+chances of data corruption going undetected is microscopic, about one
+chance in four billion for each file processed. Be aware, though, that
+the check occurs upon decompression, so it can only tell you that
+something is wrong. It can't help you
+recover the original uncompressed
+data. You can use
+.I bzip2recover
+to try to recover data from
+damaged files.
+
+Return values: 0 for a normal exit, 1 for environmental problems (file
+not found, invalid flags, I/O errors, &c), 2 to indicate a corrupt
+compressed file, 3 for an internal consistency error (eg, bug) which
+caused
+.I bzip2
+to panic.
+
+.SH OPTIONS
+.TP
+.B \-c --stdout
+Compress or decompress to standard output.
+.TP
+.B \-d --decompress
+Force decompression.
+.I bzip2,
+.I bunzip2
+and
+.I bzcat
+are
+really the same program, and the decision about what actions to take is
+done on the basis of which name is used. This flag overrides that
+mechanism, and forces
+.I bzip2
+to decompress.
+.TP
+.B \-z --compress
+The complement to \-d: forces compression, regardless of the
+invokation name.
+.TP
+.B \-t --test
+Check integrity of the specified file(s), but don't decompress them.
+This really performs a trial decompression and throws away the result.
+.TP
+.B \-f --force
+Force overwrite of output files. Normally,
+.I bzip2
+will not overwrite
+existing output files. Also forces
+.I bzip2
+to break hard links
+to files, which it otherwise wouldn't do.
+.TP
+.B \-k --keep
+Keep (don't delete) input files during compression
+or decompression.
+.TP
+.B \-s --small
+Reduce memory usage, for compression, decompression and testing. Files
+are decompressed and tested using a modified algorithm which only
+requires 2.5 bytes per block byte. This means any file can be
+decompressed in 2300k of memory, albeit at about half the normal speed.
+
+During compression, \-s selects a block size of 200k, which limits
+memory use to around the same figure, at the expense of your compression
+ratio. In short, if your machine is low on memory (8 megabytes or
+less), use \-s for everything. See MEMORY MANAGEMENT below.
+.TP
+.B \-q --quiet
+Suppress non-essential warning messages. Messages pertaining to
+I/O errors and other critical events will not be suppressed.
+.TP
+.B \-v --verbose
+Verbose mode -- show the compression ratio for each file processed.
+Further \-v's increase the verbosity level, spewing out lots of
+information which is primarily of interest for diagnostic purposes.
+.TP
+.B \-L --license -V --version
+Display the software version, license terms and conditions.
+.TP
+.B \-1 to \-9
+Set the block size to 100 k, 200 k .. 900 k when compressing. Has no
+effect when decompressing. See MEMORY MANAGEMENT below.
+.TP
+.B \--
+Treats all subsequent arguments as file names, even if they start
+with a dash. This is so you can handle files with names beginning
+with a dash, for example: bzip2 \-- \-myfilename.
+.TP
+.B \--repetitive-fast --repetitive-best
+These flags are redundant in versions 0.9.5 and above. They provided
+some coarse control over the behaviour of the sorting algorithm in
+earlier versions, which was sometimes useful. 0.9.5 and above have an
+improved algorithm which renders these flags irrelevant.
+
+.SH MEMORY MANAGEMENT
+.I bzip2
+compresses large files in blocks. The block size affects
+both the compression ratio achieved, and the amount of memory needed for
+compression and decompression. The flags \-1 through \-9
+specify the block size to be 100,000 bytes through 900,000 bytes (the
+default) respectively. At decompression time, the block size used for
+compression is read from the header of the compressed file, and
+.I bunzip2
+then allocates itself just enough memory to decompress
+the file. Since block sizes are stored in compressed files, it follows
+that the flags \-1 to \-9 are irrelevant to and so ignored
+during decompression.
+
+Compression and decompression requirements,
+in bytes, can be estimated as:
+
+ Compression: 400k + ( 8 x block size )
+
+ Decompression: 100k + ( 4 x block size ), or
+ 100k + ( 2.5 x block size )
+
+Larger block sizes give rapidly diminishing marginal returns. Most of
+the compression comes from the first two or three hundred k of block
+size, a fact worth bearing in mind when using
+.I bzip2
+on small machines.
+It is also important to appreciate that the decompression memory
+requirement is set at compression time by the choice of block size.
+
+For files compressed with the default 900k block size,
+.I bunzip2
+will require about 3700 kbytes to decompress. To support decompression
+of any file on a 4 megabyte machine,
+.I bunzip2
+has an option to
+decompress using approximately half this amount of memory, about 2300
+kbytes. Decompression speed is also halved, so you should use this
+option only where necessary. The relevant flag is -s.
+
+In general, try and use the largest block size memory constraints allow,
+since that maximises the compression achieved. Compression and
+decompression speed are virtually unaffected by block size.
+
+Another significant point applies to files which fit in a single block
+-- that means most files you'd encounter using a large block size. The
+amount of real memory touched is proportional to the size of the file,
+since the file is smaller than a block. For example, compressing a file
+20,000 bytes long with the flag -9 will cause the compressor to
+allocate around 7600k of memory, but only touch 400k + 20000 * 8 = 560
+kbytes of it. Similarly, the decompressor will allocate 3700k but only
+touch 100k + 20000 * 4 = 180 kbytes.
+
+Here is a table which summarises the maximum memory usage for different
+block sizes. Also recorded is the total compressed size for 14 files of
+the Calgary Text Compression Corpus totalling 3,141,622 bytes. This
+column gives some feel for how compression varies with block size.
+These figures tend to understate the advantage of larger block sizes for
+larger files, since the Corpus is dominated by smaller files.

+
+.SH RECOVERING DATA FROM DAMAGED FILES
+.I bzip2
+compresses files in blocks, usually 900kbytes long. Each
+block is handled independently. If a media or transmission error causes
+a multi-block .bz2
+file to become damaged, it may be possible to
+recover data from the undamaged blocks in the file.
+
+The compressed representation of each block is delimited by a 48-bit
+pattern, which makes it possible to find the block boundaries with
+reasonable certainty. Each block also carries its own 32-bit CRC, so
+damaged blocks can be distinguished from undamaged ones.
+
+.I bzip2recover
+is a simple program whose purpose is to search for
+blocks in .bz2 files, and write each block out into its own .bz2
+file. You can then use
+.I bzip2
+\-t
+to test the
+integrity of the resulting files, and decompress those which are
+undamaged.
+
+.I bzip2recover
+takes a single argument, the name of the damaged file,
+and writes a number of files "rec0001file.bz2",
+"rec0002file.bz2", etc, containing the extracted blocks.
+The output filenames are designed so that the use of
+wildcards in subsequent processing -- for example,
+"bzip2 -dc rec*file.bz2 > recovered_data" -- lists the files in
+the correct order.
+
+.I bzip2recover
+should be of most use dealing with large .bz2
+files, as these will contain many blocks. It is clearly
+futile to use it on damaged single-block files, since a
+damaged block cannot be recovered. If you wish to minimise
+any potential data loss through media or transmission errors,
+you might consider compressing with a smaller
+block size.
+
+.SH PERFORMANCE NOTES
+The sorting phase of compression gathers together similar strings in the
+file. Because of this, files containing very long runs of repeated
+symbols, like "aabaabaabaab ..." (repeated several hundred times) may
+compress more slowly than normal. Versions 0.9.5 and above fare much
+better than previous versions in this respect. The ratio between
+worst-case and average-case compression time is in the region of 10:1.
+For previous versions, this figure was more like 100:1. You can use the
+\-vvvv option to monitor progress in great detail, if you want.
+
+Decompression speed is unaffected by these phenomena.
+
+.I bzip2
+usually allocates several megabytes of memory to operate
+in, and then charges all over it in a fairly random fashion. This means
+that performance, both for compressing and decompressing, is largely
+determined by the speed at which your machine can service cache misses.
+Because of this, small changes to the code to reduce the miss rate have
+been observed to give disproportionately large performance improvements.
+I imagine
+.I bzip2
+will perform best on machines with very large caches.
+
+.SH CAVEATS
+I/O error messages are not as helpful as they could be.
+.I bzip2
+tries hard to detect I/O errors and exit cleanly, but the details of
+what the problem is sometimes seem rather misleading.
+
+This manual page pertains to version 1.0 of
+.I bzip2.
+Compressed
+data created by this version is entirely forwards and backwards
+compatible with the previous public releases, versions 0.1pl2, 0.9.0
+and 0.9.5,
+but with the following exception: 0.9.0 and above can correctly
+decompress multiple concatenated compressed files. 0.1pl2 cannot do
+this; it will stop after decompressing just the first file in the
+stream.
+
+.I bzip2recover
+uses 32-bit integers to represent bit positions in
+compressed files, so it cannot handle compressed files more than 512
+megabytes long. This could easily be fixed.

+ _b_z_i_p_2 compresses files using the Burrows-Wheeler block
+ sorting text compression algorithm, and Huffman coding.
+ Compression is generally considerably better than that
+ achieved by more conventional LZ77/LZ78-based compressors,
+ and approaches the performance of the PPM family of sta-
+ tistical compressors.
+
+ The command-line options are deliberately very similar to
+ those of _G_N_U _g_z_i_p_, but they are not identical.
+
+ _b_z_i_p_2 expects a list of file names to accompany the com-
+ mand-line flags. Each file is replaced by a compressed
+ version of itself, with the name "original_name.bz2".
+ Each compressed file has the same modification date, per-
+ missions, and, when possible, ownership as the correspond-
+ ing original, so that these properties can be correctly
+ restored at decompression time. File name handling is
+ naive in the sense that there is no mechanism for preserv-
+ ing original file names, permissions, ownerships or dates
+ in filesystems which lack these concepts, or have serious
+ file name length restrictions, such as MS-DOS.
+
+ _b_z_i_p_2 and _b_u_n_z_i_p_2 will by default not overwrite existing
+ files. If you want this to happen, specify the -f flag.
+
+ If no file names are specified, _b_z_i_p_2 compresses from
+ standard input to standard output. In this case, _b_z_i_p_2
+ will decline to write compressed output to a terminal, as
+ this would be entirely incomprehensible and therefore
+ pointless.
+
+ _b_u_n_z_i_p_2 (or _b_z_i_p_2 _-_d_) decompresses all specified files.
+ Files which were not created by _b_z_i_p_2 will be detected and
+ ignored, and a warning issued. _b_z_i_p_2 attempts to guess
+ the filename for the decompressed file from that of the
+ compressed file as follows:
+
+ filename.bz2 becomes filename
+ filename.bz becomes filename
+ filename.tbz2 becomes filename.tar
+
+
+
+ 1
+
+
+
+
+
+bzip2(1) bzip2(1)
+
+
+ filename.tbz becomes filename.tar
+ anyothername becomes anyothername.out
+
+ If the file does not end in one of the recognised endings,
+ _._b_z_2_, _._b_z_, _._t_b_z_2 or _._t_b_z_, _b_z_i_p_2 complains that it cannot
+ guess the name of the original file, and uses the original
+ name with _._o_u_t appended.
+
+ As with compression, supplying no filenames causes decom-
+ pression from standard input to standard output.
+
+ _b_u_n_z_i_p_2 will correctly decompress a file which is the con-
+ catenation of two or more compressed files. The result is
+ the concatenation of the corresponding uncompressed files.
+ Integrity testing (-t) of concatenated compressed files is
+ also supported.
+
+ You can also compress or decompress files to the standard
+ output by giving the -c flag. Multiple files may be com-
+ pressed and decompressed like this. The resulting outputs
+ are fed sequentially to stdout. Compression of multiple
+ files in this manner generates a stream containing multi-
+ ple compressed file representations. Such a stream can be
+ decompressed correctly only by _b_z_i_p_2 version 0.9.0 or
+ later. Earlier versions of _b_z_i_p_2 will stop after decom-
+ pressing the first file in the stream.
+
+ _b_z_c_a_t (or _b_z_i_p_2 _-_d_c_) decompresses all specified files to
+ the standard output.
+
+ _b_z_i_p_2 will read arguments from the environment variables
+ _B_Z_I_P_2 and _B_Z_I_P_, in that order, and will process them
+ before any arguments read from the command line. This
+ gives a convenient way to supply default arguments.
+
+ Compression is always performed, even if the compressed
+ file is slightly larger than the original. Files of less
+ than about one hundred bytes tend to get larger, since the
+ compression mechanism has a constant overhead in the
+ region of 50 bytes. Random data (including the output of
+ most file compressors) is coded at about 8.05 bits per
+ byte, giving an expansion of around 0.5%.
+
+ As a self-check for your protection, _b_z_i_p_2 uses 32-bit
+ CRCs to make sure that the decompressed version of a file
+ is identical to the original. This guards against corrup-
+ tion of the compressed data, and against undetected bugs
+ in _b_z_i_p_2 (hopefully very unlikely). The chances of data
+ corruption going undetected is microscopic, about one
+ chance in four billion for each file processed. Be aware,
+ though, that the check occurs upon decompression, so it
+ can only tell you that something is wrong. It can't help
+ you recover the original uncompressed data. You can use
+ _b_z_i_p_2_r_e_c_o_v_e_r to try to recover data from damaged files.

+
+ During compression, -s selects a block size of

+ These flags are redundant in versions 0.9.5 and

+ _b_z_i_p_2 compresses large files in blocks. The block size
+ affects both the compression ratio achieved, and the
+ amount of memory needed for compression and decompression.
+ The flags -1 through -9 specify the block size to be
+ 100,000 bytes through 900,000 bytes (the default) respec-
+ tively. At decompression time, the block size used for
+ compression is read from the header of the compressed
+ file, and _b_u_n_z_i_p_2 then allocates itself just enough memory
+ to decompress the file. Since block sizes are stored in
+ compressed files, it follows that the flags -1 to -9 are
+ irrelevant to and so ignored during decompression.
+
+ Compression and decompression requirements, in bytes, can
+ be estimated as:
+
+ Compression: 400k + ( 8 x block size )
+
+ Decompression: 100k + ( 4 x block size ), or
+ 100k + ( 2.5 x block size )
+
+ Larger block sizes give rapidly diminishing marginal
+ returns. Most of the compression comes from the first two
+
+
+
+ 4
+
+
+
+
+
+bzip2(1) bzip2(1)
+
+
+ or three hundred k of block size, a fact worth bearing in
+ mind when using _b_z_i_p_2 on small machines. It is also
+ important to appreciate that the decompression memory
+ requirement is set at compression time by the choice of
+ block size.
+
+ For files compressed with the default 900k block size,
+ _b_u_n_z_i_p_2 will require about 3700 kbytes to decompress. To
+ support decompression of any file on a 4 megabyte machine,
+ _b_u_n_z_i_p_2 has an option to decompress using approximately
+ half this amount of memory, about 2300 kbytes. Decompres-
+ sion speed is also halved, so you should use this option
+ only where necessary. The relevant flag is -s.
+
+ In general, try and use the largest block size memory con-
+ straints allow, since that maximises the compression
+ achieved. Compression and decompression speed are virtu-
+ ally unaffected by block size.
+
+ Another significant point applies to files which fit in a
+ single block -- that means most files you'd encounter
+ using a large block size. The amount of real memory
+ touched is proportional to the size of the file, since the
+ file is smaller than a block. For example, compressing a
+ file 20,000 bytes long with the flag -9 will cause the
+ compressor to allocate around 7600k of memory, but only
+ touch 400k + 20000 * 8 = 560 kbytes of it. Similarly, the
+ decompressor will allocate 3700k but only touch 100k +
+ 20000 * 4 = 180 kbytes.
+
+ Here is a table which summarises the maximum memory usage
+ for different block sizes. Also recorded is the total
+ compressed size for 14 files of the Calgary Text Compres-
+ sion Corpus totalling 3,141,622 bytes. This column gives
+ some feel for how compression varies with block size.
+ These figures tend to understate the advantage of larger
+ block sizes for larger files, since the Corpus is domi-
+ nated by smaller files.

+ _b_z_i_p_2 compresses files in blocks, usually 900kbytes long.
+ Each block is handled independently. If a media or trans-
+ mission error causes a multi-block .bz2 file to become
+ damaged, it may be possible to recover data from the
+ undamaged blocks in the file.
+
+ The compressed representation of each block is delimited
+ by a 48-bit pattern, which makes it possible to find the
+ block boundaries with reasonable certainty. Each block
+ also carries its own 32-bit CRC, so damaged blocks can be
+ distinguished from undamaged ones.
+
+ _b_z_i_p_2_r_e_c_o_v_e_r is a simple program whose purpose is to
+ search for blocks in .bz2 files, and write each block out
+ into its own .bz2 file. You can then use _b_z_i_p_2 -t to test
+ the integrity of the resulting files, and decompress those
+ which are undamaged.
+
+ _b_z_i_p_2_r_e_c_o_v_e_r takes a single argument, the name of the dam-
+ aged file, and writes a number of files "rec0001file.bz2",
+ "rec0002file.bz2", etc, containing the extracted blocks.
+ The output filenames are designed so that the use of
+ wildcards in subsequent processing -- for example, "bzip2
+ -dc rec*file.bz2 > recovered_data" -- lists the files in
+ the correct order.
+
+ _b_z_i_p_2_r_e_c_o_v_e_r should be of most use dealing with large .bz2
+ files, as these will contain many blocks. It is clearly
+ futile to use it on damaged single-block files, since a
+ damaged block cannot be recovered. If you wish to min-
+ imise any potential data loss through media or transmis-
+ sion errors, you might consider compressing with a smaller
+ block size.
+
+
+PPEERRFFOORRMMAANNCCEE NNOOTTEESS
+ The sorting phase of compression gathers together similar
+ strings in the file. Because of this, files containing
+ very long runs of repeated symbols, like "aabaabaabaab
+ ..." (repeated several hundred times) may compress more
+ slowly than normal. Versions 0.9.5 and above fare much
+ better than previous versions in this respect. The ratio
+ between worst-case and average-case compression time is in
+ the region of 10:1. For previous versions, this figure
+ was more like 100:1. You can use the -vvvv option to mon-
+ itor progress in great detail, if you want.
+
+ Decompression speed is unaffected by these phenomena.
+
+ _b_z_i_p_2 usually allocates several megabytes of memory to
+ operate in, and then charges all over it in a fairly ran-
+ dom fashion. This means that performance, both for com-
+ pressing and decompressing, is largely determined by the
+
+
+
+ 6
+
+
+
+
+
+bzip2(1) bzip2(1)
+
+
+ speed at which your machine can service cache misses.
+ Because of this, small changes to the code to reduce the
+ miss rate have been observed to give disproportionately
+ large performance improvements. I imagine _b_z_i_p_2 will per-
+ form best on machines with very large caches.
+
+
+CCAAVVEEAATTSS
+ I/O error messages are not as helpful as they could be.
+ _b_z_i_p_2 tries hard to detect I/O errors and exit cleanly,
+ but the details of what the problem is sometimes seem
+ rather misleading.
+
+ This manual page pertains to version 1.0 of _b_z_i_p_2_. Com-
+ pressed data created by this version is entirely forwards
+ and backwards compatible with the previous public
+ releases, versions 0.1pl2, 0.9.0 and 0.9.5, but with the
+ following exception: 0.9.0 and above can correctly decom-
+ press multiple concatenated compressed files. 0.1pl2 can-
+ not do this; it will stop after decompressing just the
+ first file in the stream.
+
+ _b_z_i_p_2_r_e_c_o_v_e_r uses 32-bit integers to represent bit posi-
+ tions in compressed files, so it cannot handle compressed
+ files more than 512 megabytes long. This could easily be
+ fixed.

+ WARNING:
+ This program and library (attempts to) compress data by

+ Unless you are 100% familiar with *all* the algorithms
+ contained herein, and with the consequences of modifying them,
+ you should NOT meddle with the compression or decompression

+ lead to disasterous loss of data.
+
+ DISCLAIMER:
+ I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
+ USE OF THIS PROGRAM, HOWSOEVER CAUSED.
+
+ Every compression of a file implies an assumption that the
+ compressed file can be decompressed to reproduce the original.
+ Great efforts in design, coding and testing have been made to
+ ensure that this program works correctly. However, the
+ complexity of the algorithms, and, in particular, the presence
+ of various special cases in the code which occur with very low
+ but non-zero probability make it impossible to rule out the
+ possibility of bugs remaining in the program. DO NOT COMPRESS
+ ANY DATA WITH THIS PROGRAM AND/OR LIBRARY UNLESS YOU ARE PREPARED
+ TO ACCEPT THE POSSIBILITY, HOWEVER SMALL, THAT THE DATA WILL
+ NOT BE RECOVERABLE.
+
+ That is not to say this program is inherently unreliable.
+ Indeed, I very much hope the opposite is true. bzip2/libbzip2
+ has been carefully constructed and extensively tested.
+
+ PATENTS:
+ To the best of my knowledge, bzip2/libbzip2 does not use any

+NAME
+ bzip2, bunzip2 - a block-sorting file compressor, v1.0
+ bzcat - decompresses files to stdout
+ bzip2recover - recovers data from damaged bzip2 files
+
+
+SYNOPSIS
+ bzip2 [ -cdfkqstvzVL123456789 ] [ filenames ... ]
+ bunzip2 [ -fkvsVL ] [ filenames ... ]
+ bzcat [ -s ] [ filenames ... ]
+ bzip2recover filename
+
+
+DESCRIPTION
+ bzip2 compresses files using the Burrows-Wheeler block
+ sorting text compression algorithm, and Huffman coding.
+ Compression is generally considerably better than that
+ achieved by more conventional LZ77/LZ78-based compressors,
+ and approaches the performance of the PPM family of sta-
+ tistical compressors.
+
+ The command-line options are deliberately very similar to
+ those of GNU gzip, but they are not identical.
+
+ bzip2 expects a list of file names to accompany the com-
+ mand-line flags. Each file is replaced by a compressed
+ version of itself, with the name "original_name.bz2".
+ Each compressed file has the same modification date, per-
+ missions, and, when possible, ownership as the correspond-
+ ing original, so that these properties can be correctly
+ restored at decompression time. File name handling is
+ naive in the sense that there is no mechanism for preserv-
+ ing original file names, permissions, ownerships or dates
+ in filesystems which lack these concepts, or have serious
+ file name length restrictions, such as MS-DOS.
+
+ bzip2 and bunzip2 will by default not overwrite existing
+ files. If you want this to happen, specify the -f flag.
+
+ If no file names are specified, bzip2 compresses from
+ standard input to standard output. In this case, bzip2
+ will decline to write compressed output to a terminal, as
+ this would be entirely incomprehensible and therefore
+ pointless.
+
+ bunzip2 (or bzip2 -d) decompresses all specified files.
+ Files which were not created by bzip2 will be detected and
+ ignored, and a warning issued. bzip2 attempts to guess
+ the filename for the decompressed file from that of the
+ compressed file as follows:
+
+ filename.bz2 becomes filename
+ filename.bz becomes filename
+ filename.tbz2 becomes filename.tar
+ filename.tbz becomes filename.tar
+ anyothername becomes anyothername.out
+
+ If the file does not end in one of the recognised endings,
+ .bz2, .bz, .tbz2 or .tbz, bzip2 complains that it cannot
+ guess the name of the original file, and uses the original
+ name with .out appended.
+
+ As with compression, supplying no filenames causes decom-
+ pression from standard input to standard output.
+
+ bunzip2 will correctly decompress a file which is the con-
+ catenation of two or more compressed files. The result is
+ the concatenation of the corresponding uncompressed files.
+ Integrity testing (-t) of concatenated compressed files is
+ also supported.
+
+ You can also compress or decompress files to the standard
+ output by giving the -c flag. Multiple files may be com-
+ pressed and decompressed like this. The resulting outputs
+ are fed sequentially to stdout. Compression of multiple
+ files in this manner generates a stream containing multi-
+ ple compressed file representations. Such a stream can be
+ decompressed correctly only by bzip2 version 0.9.0 or
+ later. Earlier versions of bzip2 will stop after decom-
+ pressing the first file in the stream.
+
+ bzcat (or bzip2 -dc) decompresses all specified files to
+ the standard output.
+
+ bzip2 will read arguments from the environment variables
+ BZIP2 and BZIP, in that order, and will process them
+ before any arguments read from the command line. This
+ gives a convenient way to supply default arguments.
+
+ Compression is always performed, even if the compressed
+ file is slightly larger than the original. Files of less
+ than about one hundred bytes tend to get larger, since the
+ compression mechanism has a constant overhead in the
+ region of 50 bytes. Random data (including the output of
+ most file compressors) is coded at about 8.05 bits per
+ byte, giving an expansion of around 0.5%.
+
+ As a self-check for your protection, bzip2 uses 32-bit
+ CRCs to make sure that the decompressed version of a file
+ is identical to the original. This guards against corrup-
+ tion of the compressed data, and against undetected bugs
+ in bzip2 (hopefully very unlikely). The chances of data
+ corruption going undetected is microscopic, about one
+ chance in four billion for each file processed. Be aware,
+ though, that the check occurs upon decompression, so it
+ can only tell you that something is wrong. It can't help
+ you recover the original uncompressed data. You can use
+ bzip2recover to try to recover data from damaged files.
+
+ Return values: 0 for a normal exit, 1 for environmental
+ problems (file not found, invalid flags, I/O errors, &c),
+ 2 to indicate a corrupt compressed file, 3 for an internal
+ consistency error (eg, bug) which caused bzip2 to panic.
+
+
+OPTIONS
+ -c --stdout
+ Compress or decompress to standard output.
+
+ -d --decompress
+ Force decompression. bzip2, bunzip2 and bzcat are
+ really the same program, and the decision about
+ what actions to take is done on the basis of which
+ name is used. This flag overrides that mechanism,
+ and forces bzip2 to decompress.
+
+ -z --compress
+ The complement to -d: forces compression, regard-
+ less of the invokation name.
+
+ -t --test
+ Check integrity of the specified file(s), but don't
+ decompress them. This really performs a trial
+ decompression and throws away the result.
+
+ -f --force
+ Force overwrite of output files. Normally, bzip2
+ will not overwrite existing output files. Also
+ forces bzip2 to break hard links to files, which it
+ otherwise wouldn't do.
+
+ -k --keep
+ Keep (don't delete) input files during compression
+ or decompression.
+
+ -s --small
+ Reduce memory usage, for compression, decompression
+ and testing. Files are decompressed and tested
+ using a modified algorithm which only requires 2.5
+ bytes per block byte. This means any file can be
+ decompressed in 2300k of memory, albeit at about
+ half the normal speed.
+
+ During compression, -s selects a block size of
+ 200k, which limits memory use to around the same
+ figure, at the expense of your compression ratio.
+ In short, if your machine is low on memory (8
+ megabytes or less), use -s for everything. See
+ MEMORY MANAGEMENT below.
+
+ -q --quiet
+ Suppress non-essential warning messages. Messages
+ pertaining to I/O errors and other critical events
+ will not be suppressed.
+
+ -v --verbose
+ Verbose mode -- show the compression ratio for each
+ file processed. Further -v's increase the ver-
+ bosity level, spewing out lots of information which
+ is primarily of interest for diagnostic purposes.
+
+ -L --license -V --version
+ Display the software version, license terms and
+ conditions.
+
+ -1 to -9
+ Set the block size to 100 k, 200 k .. 900 k when
+ compressing. Has no effect when decompressing.
+ See MEMORY MANAGEMENT below.
+
+ -- Treats all subsequent arguments as file names, even
+ if they start with a dash. This is so you can han-
+ dle files with names beginning with a dash, for
+ example: bzip2 -- -myfilename.
+
+ --repetitive-fast --repetitive-best
+ These flags are redundant in versions 0.9.5 and
+ above. They provided some coarse control over the
+ behaviour of the sorting algorithm in earlier ver-
+ sions, which was sometimes useful. 0.9.5 and above
+ have an improved algorithm which renders these
+ flags irrelevant.
+
+
+MEMORY MANAGEMENT
+ bzip2 compresses large files in blocks. The block size
+ affects both the compression ratio achieved, and the
+ amount of memory needed for compression and decompression.
+ The flags -1 through -9 specify the block size to be
+ 100,000 bytes through 900,000 bytes (the default) respec-
+ tively. At decompression time, the block size used for
+ compression is read from the header of the compressed
+ file, and bunzip2 then allocates itself just enough memory
+ to decompress the file. Since block sizes are stored in
+ compressed files, it follows that the flags -1 to -9 are
+ irrelevant to and so ignored during decompression.
+
+ Compression and decompression requirements, in bytes, can
+ be estimated as:
+
+ Compression: 400k + ( 8 x block size )
+
+ Decompression: 100k + ( 4 x block size ), or
+ 100k + ( 2.5 x block size )
+
+ Larger block sizes give rapidly diminishing marginal
+ returns. Most of the compression comes from the first two
+ or three hundred k of block size, a fact worth bearing in
+ mind when using bzip2 on small machines. It is also
+ important to appreciate that the decompression memory
+ requirement is set at compression time by the choice of
+ block size.
+
+ For files compressed with the default 900k block size,
+ bunzip2 will require about 3700 kbytes to decompress. To
+ support decompression of any file on a 4 megabyte machine,
+ bunzip2 has an option to decompress using approximately
+ half this amount of memory, about 2300 kbytes. Decompres-
+ sion speed is also halved, so you should use this option
+ only where necessary. The relevant flag is -s.
+
+ In general, try and use the largest block size memory con-
+ straints allow, since that maximises the compression
+ achieved. Compression and decompression speed are virtu-
+ ally unaffected by block size.
+
+ Another significant point applies to files which fit in a
+ single block -- that means most files you'd encounter
+ using a large block size. The amount of real memory
+ touched is proportional to the size of the file, since the
+ file is smaller than a block. For example, compressing a
+ file 20,000 bytes long with the flag -9 will cause the
+ compressor to allocate around 7600k of memory, but only
+ touch 400k + 20000 * 8 = 560 kbytes of it. Similarly, the
+ decompressor will allocate 3700k but only touch 100k +
+ 20000 * 4 = 180 kbytes.
+
+ Here is a table which summarises the maximum memory usage
+ for different block sizes. Also recorded is the total
+ compressed size for 14 files of the Calgary Text Compres-
+ sion Corpus totalling 3,141,622 bytes. This column gives
+ some feel for how compression varies with block size.
+ These figures tend to understate the advantage of larger
+ block sizes for larger files, since the Corpus is domi-
+ nated by smaller files.
+
+ Compress Decompress Decompress Corpus
+ Flag usage usage -s usage Size
+
+ -1 1200k 500k 350k 914704
+ -2 2000k 900k 600k 877703
+ -3 2800k 1300k 850k 860338

+
+
+RECOVERING DATA FROM DAMAGED FILES
+ bzip2 compresses files in blocks, usually 900kbytes long.
+ Each block is handled independently. If a media or trans-
+ mission error causes a multi-block .bz2 file to become
+ damaged, it may be possible to recover data from the
+ undamaged blocks in the file.
+
+ The compressed representation of each block is delimited
+ by a 48-bit pattern, which makes it possible to find the
+ block boundaries with reasonable certainty. Each block
+ also carries its own 32-bit CRC, so damaged blocks can be
+ distinguished from undamaged ones.
+
+ bzip2recover is a simple program whose purpose is to
+ search for blocks in .bz2 files, and write each block out
+ into its own .bz2 file. You can then use bzip2 -t to test
+ the integrity of the resulting files, and decompress those
+ which are undamaged.
+
+ bzip2recover takes a single argument, the name of the dam-
+ aged file, and writes a number of files "rec0001file.bz2",
+ "rec0002file.bz2", etc, containing the extracted blocks.
+ The output filenames are designed so that the use of
+ wildcards in subsequent processing -- for example, "bzip2
+ -dc rec*file.bz2 > recovered_data" -- lists the files in
+ the correct order.
+
+ bzip2recover should be of most use dealing with large .bz2
+ files, as these will contain many blocks. It is clearly
+ futile to use it on damaged single-block files, since a
+ damaged block cannot be recovered. If you wish to min-
+ imise any potential data loss through media or transmis-
+ sion errors, you might consider compressing with a smaller
+ block size.
+
+
+PERFORMANCE NOTES
+ The sorting phase of compression gathers together similar
+ strings in the file. Because of this, files containing
+ very long runs of repeated symbols, like "aabaabaabaab
+ ..." (repeated several hundred times) may compress more
+ slowly than normal. Versions 0.9.5 and above fare much
+ better than previous versions in this respect. The ratio
+ between worst-case and average-case compression time is in
+ the region of 10:1. For previous versions, this figure
+ was more like 100:1. You can use the -vvvv option to mon-
+ itor progress in great detail, if you want.
+
+ Decompression speed is unaffected by these phenomena.
+
+ bzip2 usually allocates several megabytes of memory to
+ operate in, and then charges all over it in a fairly ran-
+ dom fashion. This means that performance, both for com-
+ pressing and decompressing, is largely determined by the
+ speed at which your machine can service cache misses.
+ Because of this, small changes to the code to reduce the
+ miss rate have been observed to give disproportionately
+ large performance improvements. I imagine bzip2 will per-
+ form best on machines with very large caches.
+
+
+CAVEATS
+ I/O error messages are not as helpful as they could be.
+ bzip2 tries hard to detect I/O errors and exit cleanly,
+ but the details of what the problem is sometimes seem
+ rather misleading.
+
+ This manual page pertains to version 1.0 of bzip2. Com-
+ pressed data created by this version is entirely forwards
+ and backwards compatible with the previous public
+ releases, versions 0.1pl2, 0.9.0 and 0.9.5, but with the
+ following exception: 0.9.0 and above can correctly decom-
+ press multiple concatenated compressed files. 0.1pl2 can-
+ not do this; it will stop after decompressing just the
+ first file in the stream.
+
+ bzip2recover uses 32-bit integers to represent bit posi-
+ tions in compressed files, so it cannot handle compressed
+ files more than 512 megabytes long. This could easily be
+ fixed.

+ The ideas embodied in bzip2 are due to (at least) the fol-
+ lowing people: Michael Burrows and David Wheeler (for the
+ block sorting transformation), David Wheeler (again, for
+ the Huffman coder), Peter Fenwick (for the structured cod-
+ ing model in the original bzip, and many refinements), and
+ Alistair Moffat, Radford Neal and Ian Witten (for the
+ arithmetic coder in the original bzip). I am much
+ indebted for their help, support and advice. See the man-
+ ual in the source distribution for pointers to sources of
+ documentation. Christian von Roques encouraged me to look
+ for faster sorting algorithms, so as to speed up compres-
+ sion. Bela Lubkin encouraged me to improve the worst-case
+ compression performance. Many people sent patches, helped
+ with portability problems, lent machines, gave advice and
+ were generally helpful.

+
+@unnumberedsubsubsec DESCRIPTION
+
+@code{bzip2} compresses files using the Burrows-Wheeler block sorting
+text compression algorithm, and Huffman coding. Compression is
+generally considerably better than that achieved by more conventional
+LZ77/LZ78-based compressors, and approaches the performance of the PPM
+family of statistical compressors.
+
+The command-line options are deliberately very similar to those of GNU
+@code{gzip}, but they are not identical.
+
+@code{bzip2} expects a list of file names to accompany the command-line
+flags. Each file is replaced by a compressed version of itself, with
+the name @code{original_name.bz2}. Each compressed file has the same
+modification date, permissions, and, when possible, ownership as the
+corresponding original, so that these properties can be correctly
+restored at decompression time. File name handling is naive in the
+sense that there is no mechanism for preserving original file names,
+permissions, ownerships or dates in filesystems which lack these
+concepts, or have serious file name length restrictions, such as MS-DOS.
+
+@code{bzip2} and @code{bunzip2} will by default not overwrite existing
+files. If you want this to happen, specify the @code{-f} flag.
+
+If no file names are specified, @code{bzip2} compresses from standard
+input to standard output. In this case, @code{bzip2} will decline to
+write compressed output to a terminal, as this would be entirely
+incomprehensible and therefore pointless.
+
+@code{bunzip2} (or @code{bzip2 -d}) decompresses all
+specified files. Files which were not created by @code{bzip2}
+will be detected and ignored, and a warning issued.
+@code{bzip2} attempts to guess the filename for the decompressed file
+from that of the compressed file as follows:
+@itemize
+@item @code{filename.bz2 } becomes @code{filename}
+@item @code{filename.bz } becomes @code{filename}
+@item @code{filename.tbz2} becomes @code{filename.tar}
+@item @code{filename.tbz } becomes @code{filename.tar}
+@item @code{anyothername } becomes @code{anyothername.out}
+@end itemize
+If the file does not end in one of the recognised endings,
+@code{.bz2}, @code{.bz},
+@code{.tbz2} or @code{.tbz}, @code{bzip2} complains that it cannot
+guess the name of the original file, and uses the original name
+with @code{.out} appended.
+
+As with compression, supplying no
+filenames causes decompression from standard input to standard output.
+
+@code{bunzip2} will correctly decompress a file which is the
+concatenation of two or more compressed files. The result is the
+concatenation of the corresponding uncompressed files. Integrity
+testing (@code{-t}) of concatenated compressed files is also supported.
+
+You can also compress or decompress files to the standard output by
+giving the @code{-c} flag. Multiple files may be compressed and
+decompressed like this. The resulting outputs are fed sequentially to
+stdout. Compression of multiple files in this manner generates a stream
+containing multiple compressed file representations. Such a stream
+can be decompressed correctly only by @code{bzip2} version 0.9.0 or
+later. Earlier versions of @code{bzip2} will stop after decompressing
+the first file in the stream.
+
+@code{bzcat} (or @code{bzip2 -dc}) decompresses all specified files to
+the standard output.
+
+@code{bzip2} will read arguments from the environment variables
+@code{BZIP2} and @code{BZIP}, in that order, and will process them
+before any arguments read from the command line. This gives a
+convenient way to supply default arguments.
+
+Compression is always performed, even if the compressed file is slightly
+larger than the original. Files of less than about one hundred bytes
+tend to get larger, since the compression mechanism has a constant
+overhead in the region of 50 bytes. Random data (including the output
+of most file compressors) is coded at about 8.05 bits per byte, giving
+an expansion of around 0.5%.
+
+As a self-check for your protection, @code{bzip2} uses 32-bit CRCs to
+make sure that the decompressed version of a file is identical to the
+original. This guards against corruption of the compressed data, and
+against undetected bugs in @code{bzip2} (hopefully very unlikely). The
+chances of data corruption going undetected is microscopic, about one
+chance in four billion for each file processed. Be aware, though, that
+the check occurs upon decompression, so it can only tell you that
+something is wrong. It can't help you recover the original uncompressed
+data. You can use @code{bzip2recover} to try to recover data from
+damaged files.
+
+Return values: 0 for a normal exit, 1 for environmental problems (file
+not found, invalid flags, I/O errors, &c), 2 to indicate a corrupt
+compressed file, 3 for an internal consistency error (eg, bug) which
+caused @code{bzip2} to panic.
+
+
+@unnumberedsubsubsec OPTIONS
+@table @code
+@item -c --stdout
+Compress or decompress to standard output.
+@item -d --decompress
+Force decompression. @code{bzip2}, @code{bunzip2} and @code{bzcat} are
+really the same program, and the decision about what actions to take is
+done on the basis of which name is used. This flag overrides that
+mechanism, and forces bzip2 to decompress.
+@item -z --compress
+The complement to @code{-d}: forces compression, regardless of the
+invokation name.
+@item -t --test
+Check integrity of the specified file(s), but don't decompress them.
+This really performs a trial decompression and throws away the result.
+@item -f --force
+Force overwrite of output files. Normally, @code{bzip2} will not overwrite
+existing output files. Also forces @code{bzip2} to break hard links
+to files, which it otherwise wouldn't do.
+@item -k --keep
+Keep (don't delete) input files during compression
+or decompression.
+@item -s --small
+Reduce memory usage, for compression, decompression and testing. Files
+are decompressed and tested using a modified algorithm which only
+requires 2.5 bytes per block byte. This means any file can be
+decompressed in 2300k of memory, albeit at about half the normal speed.
+
+During compression, @code{-s} selects a block size of 200k, which limits
+memory use to around the same figure, at the expense of your compression
+ratio. In short, if your machine is low on memory (8 megabytes or
+less), use -s for everything. See MEMORY MANAGEMENT below.
+@item -q --quiet
+Suppress non-essential warning messages. Messages pertaining to
+I/O errors and other critical events will not be suppressed.
+@item -v --verbose
+Verbose mode -- show the compression ratio for each file processed.
+Further @code{-v}'s increase the verbosity level, spewing out lots of
+information which is primarily of interest for diagnostic purposes.
+@item -L --license -V --version
+Display the software version, license terms and conditions.
+@item -1 to -9
+Set the block size to 100 k, 200 k .. 900 k when compressing. Has no
+effect when decompressing. See MEMORY MANAGEMENT below.
+@item --
+Treats all subsequent arguments as file names, even if they start
+with a dash. This is so you can handle files with names beginning
+with a dash, for example: @code{bzip2 -- -myfilename}.
+@item --repetitive-fast
+@item --repetitive-best
+These flags are redundant in versions 0.9.5 and above. They provided
+some coarse control over the behaviour of the sorting algorithm in
+earlier versions, which was sometimes useful. 0.9.5 and above have an
+improved algorithm which renders these flags irrelevant.
+@end table
+
+
+@unnumberedsubsubsec MEMORY MANAGEMENT
+
+@code{bzip2} compresses large files in blocks. The block size affects
+both the compression ratio achieved, and the amount of memory needed for
+compression and decompression. The flags @code{-1} through @code{-9}
+specify the block size to be 100,000 bytes through 900,000 bytes (the
+default) respectively. At decompression time, the block size used for
+compression is read from the header of the compressed file, and
+@code{bunzip2} then allocates itself just enough memory to decompress
+the file. Since block sizes are stored in compressed files, it follows
+that the flags @code{-1} to @code{-9} are irrelevant to and so ignored
+during decompression.
+
+Compression and decompression requirements, in bytes, can be estimated
+as:
+@example
+ Compression: 400k + ( 8 x block size )
+
+ Decompression: 100k + ( 4 x block size ), or
+ 100k + ( 2.5 x block size )
+@end example
+Larger block sizes give rapidly diminishing marginal returns. Most of
+the compression comes from the first two or three hundred k of block
+size, a fact worth bearing in mind when using @code{bzip2} on small machines.
+It is also important to appreciate that the decompression memory
+requirement is set at compression time by the choice of block size.
+
+For files compressed with the default 900k block size, @code{bunzip2}
+will require about 3700 kbytes to decompress. To support decompression
+of any file on a 4 megabyte machine, @code{bunzip2} has an option to
+decompress using approximately half this amount of memory, about 2300
+kbytes. Decompression speed is also halved, so you should use this
+option only where necessary. The relevant flag is @code{-s}.
+
+In general, try and use the largest block size memory constraints allow,
+since that maximises the compression achieved. Compression and
+decompression speed are virtually unaffected by block size.
+
+Another significant point applies to files which fit in a single block
+-- that means most files you'd encounter using a large block size. The
+amount of real memory touched is proportional to the size of the file,
+since the file is smaller than a block. For example, compressing a file
+20,000 bytes long with the flag @code{-9} will cause the compressor to
+allocate around 7600k of memory, but only touch 400k + 20000 * 8 = 560
+kbytes of it. Similarly, the decompressor will allocate 3700k but only
+touch 100k + 20000 * 4 = 180 kbytes.
+
+Here is a table which summarises the maximum memory usage for different
+block sizes. Also recorded is the total compressed size for 14 files of
+the Calgary Text Compression Corpus totalling 3,141,622 bytes. This
+column gives some feel for how compression varies with block size.
+These figures tend to understate the advantage of larger block sizes for
+larger files, since the Corpus is dominated by smaller files.
+@example
+ Compress Decompress Decompress Corpus
+ Flag usage usage -s usage Size
+
+ -1 1200k 500k 350k 914704
+ -2 2000k 900k 600k 877703
+ -3 2800k 1300k 850k 860338
+ -4 3600k 1700k 1100k 846899
+ -5 4400k 2100k 1350k 845160
+ -6 5200k 2500k 1600k 838626
+ -7 6100k 2900k 1850k 834096
+ -8 6800k 3300k 2100k 828642
+ -9 7600k 3700k 2350k 828642
+@end example
+
+@unnumberedsubsubsec RECOVERING DATA FROM DAMAGED FILES
+
+@code{bzip2} compresses files in blocks, usually 900kbytes long. Each
+block is handled independently. If a media or transmission error causes
+a multi-block @code{.bz2} file to become damaged, it may be possible to
+recover data from the undamaged blocks in the file.
+
+The compressed representation of each block is delimited by a 48-bit
+pattern, which makes it possible to find the block boundaries with
+reasonable certainty. Each block also carries its own 32-bit CRC, so
+damaged blocks can be distinguished from undamaged ones.
+
+@code{bzip2recover} is a simple program whose purpose is to search for
+blocks in @code{.bz2} files, and write each block out into its own
+@code{.bz2} file. You can then use @code{bzip2 -t} to test the
+integrity of the resulting files, and decompress those which are
+undamaged.
+
+@code{bzip2recover}
+takes a single argument, the name of the damaged file,
+and writes a number of files @code{rec0001file.bz2},
+ @code{rec0002file.bz2}, etc, containing the extracted blocks.
+ The output filenames are designed so that the use of
+ wildcards in subsequent processing -- for example,
+@code{bzip2 -dc rec*file.bz2 > recovered_data} -- lists the files in
+ the correct order.
+
+@code{bzip2recover} should be of most use dealing with large @code{.bz2}
+ files, as these will contain many blocks. It is clearly
+ futile to use it on damaged single-block files, since a
+ damaged block cannot be recovered. If you wish to minimise
+any potential data loss through media or transmission errors,
+you might consider compressing with a smaller
+ block size.
+
+
+@unnumberedsubsubsec PERFORMANCE NOTES
+
+The sorting phase of compression gathers together similar strings in the
+file. Because of this, files containing very long runs of repeated
+symbols, like "aabaabaabaab ..." (repeated several hundred times) may
+compress more slowly than normal. Versions 0.9.5 and above fare much
+better than previous versions in this respect. The ratio between
+worst-case and average-case compression time is in the region of 10:1.
+For previous versions, this figure was more like 100:1. You can use the
+@code{-vvvv} option to monitor progress in great detail, if you want.
+
+Decompression speed is unaffected by these phenomena.
+
+@code{bzip2} usually allocates several megabytes of memory to operate
+in, and then charges all over it in a fairly random fashion. This means
+that performance, both for compressing and decompressing, is largely
+determined by the speed at which your machine can service cache misses.
+Because of this, small changes to the code to reduce the miss rate have
+been observed to give disproportionately large performance improvements.
+I imagine @code{bzip2} will perform best on machines with very large
+caches.
+
+
+@unnumberedsubsubsec CAVEATS
+
+I/O error messages are not as helpful as they could be. @code{bzip2}
+tries hard to detect I/O errors and exit cleanly, but the details of
+what the problem is sometimes seem rather misleading.
+
+This manual page pertains to version 1.0 of @code{bzip2}. Compressed
+data created by this version is entirely forwards and backwards
+compatible with the previous public releases, versions 0.1pl2, 0.9.0 and
+0.9.5, but with the following exception: 0.9.0 and above can correctly
+decompress multiple concatenated compressed files. 0.1pl2 cannot do
+this; it will stop after decompressing just the first file in the
+stream.
+
+@code{bzip2recover} uses 32-bit integers to represent bit positions in
+compressed files, so it cannot handle compressed files more than 512
+megabytes long. This could easily be fixed.
+
+
+@unnumberedsubsubsec AUTHOR
+Julian Seward, @code{jseward@@acm.org}.
+
+The ideas embodied in @code{bzip2} are due to (at least) the following
+people: Michael Burrows and David Wheeler (for the block sorting
+transformation), David Wheeler (again, for the Huffman coder), Peter
+Fenwick (for the structured coding model in the original @code{bzip},
+and many refinements), and Alistair Moffat, Radford Neal and Ian Witten
+(for the arithmetic coder in the original @code{bzip}). I am much
+indebted for their help, support and advice. See the manual in the
+source distribution for pointers to sources of documentation. Christian
+von Roques encouraged me to look for faster sorting algorithms, so as to
+speed up compression. Bela Lubkin encouraged me to improve the
+worst-case compression performance. Many people sent patches, helped
+with portability problems, lent machines, gave advice and were generally
+helpful.

+
+@chapter Programming with @code{libbzip2}
+
+This chapter describes the programming interface to @code{libbzip2}.
+
+For general background information, particularly about memory
+use and performance aspects, you'd be well advised to read Chapter 2
+as well.
+
+@section Top-level structure
+
+@code{libbzip2} is a flexible library for compressing and decompressing
+data in the @code{bzip2} data format. Although packaged as a single
+entity, it helps to regard the library as three separate parts: the low
+level interface, and the high level interface, and some utility
+functions.
+
+The structure of @code{libbzip2}'s interfaces is similar to
+that of Jean-loup Gailly's and Mark Adler's excellent @code{zlib}
+library.
+
+All externally visible symbols have names beginning @code{BZ2_}.
+This is new in version 1.0. The intention is to minimise pollution
+of the namespaces of library clients.
+
+@subsection Low-level summary
+
+This interface provides services for compressing and decompressing
+data in memory. There's no provision for dealing with files, streams
+or any other I/O mechanisms, just straight memory-to-memory work.
+In fact, this part of the library can be compiled without inclusion
+of @code{stdio.h}, which may be helpful for embedded applications.
+
+The low-level part of the library has no global variables and
+is therefore thread-safe.
+
+Six routines make up the low level interface:
+@code{BZ2_bzCompressInit}, @code{BZ2_bzCompress}, and @* @code{BZ2_bzCompressEnd}
+for compression,
+and a corresponding trio @code{BZ2_bzDecompressInit}, @* @code{BZ2_bzDecompress}
+and @code{BZ2_bzDecompressEnd} for decompression.
+The @code{*Init} functions allocate
+memory for compression/decompression and do other
+initialisations, whilst the @code{*End} functions close down operations
+and release memory.
+
+The real work is done by @code{BZ2_bzCompress} and @code{BZ2_bzDecompress}.
+These compress and decompress data from a user-supplied input buffer
+to a user-supplied output buffer. These buffers can be any size;
+arbitrary quantities of data are handled by making repeated calls
+to these functions. This is a flexible mechanism allowing a
+consumer-pull style of activity, or producer-push, or a mixture of
+both.
+
+
+
+@subsection High-level summary
+
+This interface provides some handy wrappers around the low-level
+interface to facilitate reading and writing @code{bzip2} format
+files (@code{.bz2} files). The routines provide hooks to facilitate
+reading files in which the @code{bzip2} data stream is embedded
+within some larger-scale file structure, or where there are
+multiple @code{bzip2} data streams concatenated end-to-end.
+
+For reading files, @code{BZ2_bzReadOpen}, @code{BZ2_bzRead},
+@code{BZ2_bzReadClose} and @* @code{BZ2_bzReadGetUnused} are supplied. For
+writing files, @code{BZ2_bzWriteOpen}, @code{BZ2_bzWrite} and
+@code{BZ2_bzWriteFinish} are available.
+
+As with the low-level library, no global variables are used
+so the library is per se thread-safe. However, if I/O errors
+occur whilst reading or writing the underlying compressed files,
+you may have to consult @code{errno} to determine the cause of
+the error. In that case, you'd need a C library which correctly
+supports @code{errno} in a multithreaded environment.
+
+To make the library a little simpler and more portable,
+@code{BZ2_bzReadOpen} and @code{BZ2_bzWriteOpen} require you to pass them file
+handles (@code{FILE*}s) which have previously been opened for reading or
+writing respectively. That avoids portability problems associated with
+file operations and file attributes, whilst not being much of an
+imposition on the programmer.
+
+
+
+@subsection Utility functions summary
+For very simple needs, @code{BZ2_bzBuffToBuffCompress} and
+@code{BZ2_bzBuffToBuffDecompress} are provided. These compress
+data in memory from one buffer to another buffer in a single
+function call. You should assess whether these functions
+fulfill your memory-to-memory compression/decompression
+requirements before investing effort in understanding the more
+general but more complex low-level interface.
+
+Yoshioka Tsuneo (@code{QWF00133@@niftyserve.or.jp} /
+@code{tsuneo-y@@is.aist-nara.ac.jp}) has contributed some functions to
+give better @code{zlib} compatibility. These functions are
+@code{BZ2_bzopen}, @code{BZ2_bzread}, @code{BZ2_bzwrite}, @code{BZ2_bzflush},
+@code{BZ2_bzclose},
+@code{BZ2_bzerror} and @code{BZ2_bzlibVersion}. You may find these functions
+more convenient for simple file reading and writing, than those in the
+high-level interface. These functions are not (yet) officially part of
+the library, and are minimally documented here. If they break, you
+get to keep all the pieces. I hope to document them properly when time
+permits.
+
+Yoshioka also contributed modifications to allow the library to be
+built as a Windows DLL.
+
+
+@section Error handling
+
+The library is designed to recover cleanly in all situations, including
+the worst-case situation of decompressing random data. I'm not
+100% sure that it can always do this, so you might want to add
+a signal handler to catch segmentation violations during decompression
+if you are feeling especially paranoid. I would be interested in
+hearing more about the robustness of the library to corrupted
+compressed data.
+
+Version 1.0 is much more robust in this respect than
+0.9.0 or 0.9.5. Investigations with Checker (a tool for
+detecting problems with memory management, similar to Purify)
+indicate that, at least for the few files I tested, all single-bit
+errors in the decompressed data are caught properly, with no
+segmentation faults, no reads of uninitialised data and no
+out of range reads or writes. So it's certainly much improved,
+although I wouldn't claim it to be totally bombproof.
+
+The file @code{bzlib.h} contains all definitions needed to use
+the library. In particular, you should definitely not include
+@code{bzlib_private.h}.
+
+In @code{bzlib.h}, the various return values are defined. The following
+list is not intended as an exhaustive description of the circumstances
+in which a given value may be returned -- those descriptions are given
+later. Rather, it is intended to convey the rough meaning of each
+return value. The first five actions are normal and not intended to
+denote an error situation.
+@table @code
+@item BZ_OK
+The requested action was completed successfully.
+@item BZ_RUN_OK
+@itemx BZ_FLUSH_OK
+@itemx BZ_FINISH_OK
+In @code{BZ2_bzCompress}, the requested flush/finish/nothing-special action
+was completed successfully.
+@item BZ_STREAM_END
+Compression of data was completed, or the logical stream end was
+detected during decompression.
+@end table
+
+The following return values indicate an error of some kind.
+@table @code
+@item BZ_CONFIG_ERROR
+Indicates that the library has been improperly compiled on your
+platform -- a major configuration error. Specifically, it means
+that @code{sizeof(char)}, @code{sizeof(short)} and @code{sizeof(int)}
+are not 1, 2 and 4 respectively, as they should be. Note that the
+library should still work properly on 64-bit platforms which follow
+the LP64 programming model -- that is, where @code{sizeof(long)}
+and @code{sizeof(void*)} are 8. Under LP64, @code{sizeof(int)} is
+still 4, so @code{libbzip2}, which doesn't use the @code{long} type,
+is OK.
+@item BZ_SEQUENCE_ERROR
+When using the library, it is important to call the functions in the
+correct sequence and with data structures (buffers etc) in the correct
+states. @code{libbzip2} checks as much as it can to ensure this is
+happening, and returns @code{BZ_SEQUENCE_ERROR} if not. Code which
+complies precisely with the function semantics, as detailed below,
+should never receive this value; such an event denotes buggy code
+which you should investigate.
+@item BZ_PARAM_ERROR
+Returned when a parameter to a function call is out of range
+or otherwise manifestly incorrect. As with @code{BZ_SEQUENCE_ERROR},
+this denotes a bug in the client code. The distinction between
+@code{BZ_PARAM_ERROR} and @code{BZ_SEQUENCE_ERROR} is a bit hazy, but still worth
+making.
+@item BZ_MEM_ERROR
+Returned when a request to allocate memory failed. Note that the
+quantity of memory needed to decompress a stream cannot be determined
+until the stream's header has been read. So @code{BZ2_bzDecompress} and
+@code{BZ2_bzRead} may return @code{BZ_MEM_ERROR} even though some of
+the compressed data has been read. The same is not true for
+compression; once @code{BZ2_bzCompressInit} or @code{BZ2_bzWriteOpen} have
+successfully completed, @code{BZ_MEM_ERROR} cannot occur.
+@item BZ_DATA_ERROR
+Returned when a data integrity error is detected during decompression.
+Most importantly, this means when stored and computed CRCs for the
+data do not match. This value is also returned upon detection of any
+other anomaly in the compressed data.
+@item BZ_DATA_ERROR_MAGIC
+As a special case of @code{BZ_DATA_ERROR}, it is sometimes useful to
+know when the compressed stream does not start with the correct
+magic bytes (@code{'B' 'Z' 'h'}).
+@item BZ_IO_ERROR
+Returned by @code{BZ2_bzRead} and @code{BZ2_bzWrite} when there is an error
+reading or writing in the compressed file, and by @code{BZ2_bzReadOpen}
+and @code{BZ2_bzWriteOpen} for attempts to use a file for which the
+error indicator (viz, @code{ferror(f)}) is set.
+On receipt of @code{BZ_IO_ERROR}, the caller should consult
+@code{errno} and/or @code{perror} to acquire operating-system
+specific information about the problem.
+@item BZ_UNEXPECTED_EOF
+Returned by @code{BZ2_bzRead} when the compressed file finishes
+before the logical end of stream is detected.
+@item BZ_OUTBUFF_FULL
+Returned by @code{BZ2_bzBuffToBuffCompress} and
+@code{BZ2_bzBuffToBuffDecompress} to indicate that the output data
+will not fit into the output buffer provided.

+
+@end example
+
+Prepares for compression. The @code{bz_stream} structure
+holds all data pertaining to the compression activity.
+A @code{bz_stream} structure should be allocated and initialised
+prior to the call.
+The fields of @code{bz_stream}
+comprise the entirety of the user-visible data. @code{state}
+is a pointer to the private data structures required for compression.
+
+Custom memory allocators are supported, via fields @code{bzalloc},
+@code{bzfree},
+and @code{opaque}. The value
+@code{opaque} is passed to as the first argument to
+all calls to @code{bzalloc} and @code{bzfree}, but is
+otherwise ignored by the library.
+The call @code{bzalloc ( opaque, n, m )} is expected to return a
+pointer @code{p} to
+@code{n * m} bytes of memory, and @code{bzfree ( opaque, p )}
+should free
+that memory.
+
+If you don't want to use a custom memory allocator, set @code{bzalloc},
+@code{bzfree} and
+@code{opaque} to @code{NULL},
+and the library will then use the standard @code{malloc}/@code{free}
+routines.
+
+Before calling @code{BZ2_bzCompressInit}, fields @code{bzalloc},
+@code{bzfree} and @code{opaque} should
+be filled appropriately, as just described. Upon return, the internal
+state will have been allocated and initialised, and @code{total_in_lo32},
+@code{total_in_hi32}, @code{total_out_lo32} and
+@code{total_out_hi32} will have been set to zero.
+These four fields are used by the library
+to inform the caller of the total amount of data passed into and out of
+the library, respectively. You should not try to change them.
+As of version 1.0, 64-bit counts are maintained, even on 32-bit
+platforms, using the @code{_hi32} fields to store the upper 32 bits
+of the count. So, for example, the total amount of data in
+is @code{(total_in_hi32 << 32) + total_in_lo32}.
+
+Parameter @code{blockSize100k} specifies the block size to be used for
+compression. It should be a value between 1 and 9 inclusive, and the
+actual block size used is 100000 x this figure. 9 gives the best
+compression but takes most memory.
+
+Parameter @code{verbosity} should be set to a number between 0 and 4
+inclusive. 0 is silent, and greater numbers give increasingly verbose
+monitoring/debugging output. If the library has been compiled with
+@code{-DBZ_NO_STDIO}, no such output will appear for any verbosity
+setting.
+
+Parameter @code{workFactor} controls how the compression phase behaves
+when presented with worst case, highly repetitive, input data. If
+compression runs into difficulties caused by repetitive data, the
+library switches from the standard sorting algorithm to a fallback
+algorithm. The fallback is slower than the standard algorithm by
+perhaps a factor of three, but always behaves reasonably, no matter how
+bad the input.
+
+Lower values of @code{workFactor} reduce the amount of effort the
+standard algorithm will expend before resorting to the fallback. You
+should set this parameter carefully; too low, and many inputs will be
+handled by the fallback algorithm and so compress rather slowly, too
+high, and your average-to-worst case compression times can become very
+large. The default value of 30 gives reasonable behaviour over a wide
+range of circumstances.
+
+Allowable values range from 0 to 250 inclusive. 0 is a special case,
+equivalent to using the default value of 30.
+
+Note that the compressed output generated is the same regardless of
+whether or not the fallback algorithm is used.
+
+Be aware also that this parameter may disappear entirely in future
+versions of the library. In principle it should be possible to devise a
+good way to automatically choose which algorithm to use. Such a
+mechanism would render the parameter obsolete.

+
+@subsection @code{BZ2_bzCompress}
+@example
+ int BZ2_bzCompress ( bz_stream *strm, int action );
+@end example
+Provides more input and/or output buffer space for the library. The
+caller maintains input and output buffers, and calls @code{BZ2_bzCompress} to
+transfer data between them.
+
+Before each call to @code{BZ2_bzCompress}, @code{next_in} should point at
+the data to be compressed, and @code{avail_in} should indicate how many
+bytes the library may read. @code{BZ2_bzCompress} updates @code{next_in},
+@code{avail_in} and @code{total_in} to reflect the number of bytes it
+has read.
+
+Similarly, @code{next_out} should point to a buffer in which the
+compressed data is to be placed, with @code{avail_out} indicating how
+much output space is available. @code{BZ2_bzCompress} updates
+@code{next_out}, @code{avail_out} and @code{total_out} to reflect the
+number of bytes output.
+
+You may provide and remove as little or as much data as you like on each
+call of @code{BZ2_bzCompress}. In the limit, it is acceptable to supply and
+remove data one byte at a time, although this would be terribly
+inefficient. You should always ensure that at least one byte of output
+space is available at each call.
+
+A second purpose of @code{BZ2_bzCompress} is to request a change of mode of the
+compressed stream.
+
+Conceptually, a compressed stream can be in one of four states: IDLE,
+RUNNING, FLUSHING and FINISHING. Before initialisation
+(@code{BZ2_bzCompressInit}) and after termination (@code{BZ2_bzCompressEnd}), a
+stream is regarded as IDLE.
+
+Upon initialisation (@code{BZ2_bzCompressInit}), the stream is placed in the
+RUNNING state. Subsequent calls to @code{BZ2_bzCompress} should pass
+@code{BZ_RUN} as the requested action; other actions are illegal and
+will result in @code{BZ_SEQUENCE_ERROR}.
+
+At some point, the calling program will have provided all the input data
+it wants to. It will then want to finish up -- in effect, asking the
+library to process any data it might have buffered internally. In this
+state, @code{BZ2_bzCompress} will no longer attempt to read data from
+@code{next_in}, but it will want to write data to @code{next_out}.
+Because the output buffer supplied by the user can be arbitrarily small,
+the finishing-up operation cannot necessarily be done with a single call
+of @code{BZ2_bzCompress}.
+
+Instead, the calling program passes @code{BZ_FINISH} as an action to
+@code{BZ2_bzCompress}. This changes the stream's state to FINISHING. Any
+remaining input (ie, @code{next_in[0 .. avail_in-1]}) is compressed and
+transferred to the output buffer. To do this, @code{BZ2_bzCompress} must be
+called repeatedly until all the output has been consumed. At that
+point, @code{BZ2_bzCompress} returns @code{BZ_STREAM_END}, and the stream's
+state is set back to IDLE. @code{BZ2_bzCompressEnd} should then be
+called.
+
+Just to make sure the calling program does not cheat, the library makes
+a note of @code{avail_in} at the time of the first call to
+@code{BZ2_bzCompress} which has @code{BZ_FINISH} as an action (ie, at the
+time the program has announced its intention to not supply any more
+input). By comparing this value with that of @code{avail_in} over
+subsequent calls to @code{BZ2_bzCompress}, the library can detect any
+attempts to slip in more data to compress. Any calls for which this is
+detected will return @code{BZ_SEQUENCE_ERROR}. This indicates a
+programming mistake which should be corrected.
+
+Instead of asking to finish, the calling program may ask
+@code{BZ2_bzCompress} to take all the remaining input, compress it and
+terminate the current (Burrows-Wheeler) compression block. This could
+be useful for error control purposes. The mechanism is analogous to
+that for finishing: call @code{BZ2_bzCompress} with an action of
+@code{BZ_FLUSH}, remove output data, and persist with the
+@code{BZ_FLUSH} action until the value @code{BZ_RUN} is returned. As
+with finishing, @code{BZ2_bzCompress} detects any attempt to provide more
+input data once the flush has begun.
+
+Once the flush is complete, the stream returns to the normal RUNNING
+state.
+
+This all sounds pretty complex, but isn't really. Here's a table
+which shows which actions are allowable in each state, what action
+will be taken, what the next state is, and what the non-error return
+values are. Note that you can't explicitly ask what state the
+stream is in, but nor do you need to -- it can be inferred from the
+values returned by @code{BZ2_bzCompress}.
+@display
+IDLE/@code{any}
+ Illegal. IDLE state only exists after @code{BZ2_bzCompressEnd} or
+ before @code{BZ2_bzCompressInit}.

+
+FLUSHING/@code{BZ_FLUSH}

+
+That still looks complicated? Well, fair enough. The usual sequence
+of calls for compressing a load of data is:
+@itemize @bullet
+@item Get started with @code{BZ2_bzCompressInit}.
+@item Shovel data in and shlurp out its compressed form using zero or more
+calls of @code{BZ2_bzCompress} with action = @code{BZ_RUN}.
+@item Finish up.
+Repeatedly call @code{BZ2_bzCompress} with action = @code{BZ_FINISH},
+copying out the compressed output, until @code{BZ_STREAM_END} is returned.
+@item Close up and go home. Call @code{BZ2_bzCompressEnd}.
+@end itemize
+If the data you want to compress fits into your input buffer all
+at once, you can skip the calls of @code{BZ2_bzCompress ( ..., BZ_RUN )} and
+just do the @code{BZ2_bzCompress ( ..., BZ_FINISH )} calls.
+
+All required memory is allocated by @code{BZ2_bzCompressInit}. The
+compression library can accept any data at all (obviously). So you
+shouldn't get any error return values from the @code{BZ2_bzCompress} calls.
+If you do, they will be @code{BZ_SEQUENCE_ERROR}, and indicate a bug in
+your programming.

+Prepares for decompression. As with @code{BZ2_bzCompressInit}, a
+@code{bz_stream} record should be allocated and initialised before the
+call. Fields @code{bzalloc}, @code{bzfree} and @code{opaque} should be
+set if a custom memory allocator is required, or made @code{NULL} for
+the normal @code{malloc}/@code{free} routines. Upon return, the internal
+state will have been initialised, and @code{total_in} and
+@code{total_out} will be zero.
+
+For the meaning of parameter @code{verbosity}, see @code{BZ2_bzCompressInit}.
+
+If @code{small} is nonzero, the library will use an alternative
+decompression algorithm which uses less memory but at the cost of
+decompressing more slowly (roughly speaking, half the speed, but the
+maximum memory requirement drops to around 2300k). See Chapter 2 for
+more information on memory management.
+
+Note that the amount of memory needed to decompress
+a stream cannot be determined until the stream's header has been read,

+Provides more input and/out output buffer space for the library. The

+
+Before each call to @code{BZ2_bzDecompress}, @code{next_in}

+and @code{total_in}
+to reflect the number of bytes it has read.
+
+Similarly, @code{next_out} should point to a buffer in which the uncompressed

+is available. @code{BZ2_bzCompress} updates @code{next_out},

+@section High-level interface
+
+This interface provides functions for reading and writing
+@code{bzip2} format files. First, some general points.
+
+@itemize @bullet
+@item All of the functions take an @code{int*} first argument,
+ @code{bzerror}.
+ After each call, @code{bzerror} should be consulted first to determine
+ the outcome of the call. If @code{bzerror} is @code{BZ_OK},
+ the call completed
+ successfully, and only then should the return value of the function
+ (if any) be consulted. If @code{bzerror} is @code{BZ_IO_ERROR},
+ there was an error
+ reading/writing the underlying compressed file, and you should
+ then consult @code{errno}/@code{perror} to determine the
+ cause of the difficulty.
+ @code{bzerror} may also be set to various other values; precise details are
+ given on a per-function basis below.
+@item If @code{bzerror} indicates an error
+ (ie, anything except @code{BZ_OK} and @code{BZ_STREAM_END}),
+ you should immediately call @code{BZ2_bzReadClose} (or @code{BZ2_bzWriteClose},
+ depending on whether you are attempting to read or to write)
+ to free up all resources associated
+ with the stream. Once an error has been indicated, behaviour of all calls
+ except @code{BZ2_bzReadClose} (@code{BZ2_bzWriteClose}) is undefined.
+ The implication is that (1) @code{bzerror} should
+ be checked after each call, and (2) if @code{bzerror} indicates an error,
+ @code{BZ2_bzReadClose} (@code{BZ2_bzWriteClose}) should then be called to clean up.
+@item The @code{FILE*} arguments passed to
+ @code{BZ2_bzReadOpen}/@code{BZ2_bzWriteOpen}
+ should be set to binary mode.
+ Most Unix systems will do this by default, but other platforms,
+ including Windows and Mac, will not. If you omit this, you may
+ encounter problems when moving code to new platforms.
+@item Memory allocation requests are handled by
+ @code{malloc}/@code{free}.
+ At present
+ there is no facility for user-defined memory allocators in the file I/O
+ functions (could easily be added, though).
+@end itemize
+
+
+
+@subsection @code{BZ2_bzReadOpen}
+@example
+ typedef void BZFILE;
+
+ BZFILE *BZ2_bzReadOpen ( int *bzerror, FILE *f,
+ int small, int verbosity,
+ void *unused, int nUnused );
+@end example
+Prepare to read compressed data from file handle @code{f}. @code{f}
+should refer to a file which has been opened for reading, and for which
+the error indicator (@code{ferror(f)})is not set. If @code{small} is 1,
+the library will try to decompress using less memory, at the expense of
+speed.
+
+For reasons explained below, @code{BZ2_bzRead} will decompress the
+@code{nUnused} bytes starting at @code{unused}, before starting to read
+from the file @code{f}. At most @code{BZ_MAX_UNUSED} bytes may be
+supplied like this. If this facility is not required, you should pass
+@code{NULL} and @code{0} for @code{unused} and n@code{Unused}
+respectively.
+
+For the meaning of parameters @code{small} and @code{verbosity},
+see @code{BZ2_bzDecompressInit}.
+
+The amount of memory needed to decompress a file cannot be determined
+until the file's header has been read. So it is possible that
+@code{BZ2_bzReadOpen} returns @code{BZ_OK} but a subsequent call of
+@code{BZ2_bzRead} will return @code{BZ_MEM_ERROR}.

+@code{b} into
+the buffer @code{buf}. If the read was successful,
+@code{bzerror} is set to @code{BZ_OK}

+was detected, @code{bzerror} will be set to @code{BZ_STREAM_END},
+and the number
+of bytes read is returned. All other @code{bzerror} values denote an error.
+
+@code{BZ2_bzRead} will supply @code{len} bytes,
+unless the logical stream end is detected
+or an error occurs. Because of this, it is possible to detect the
+stream end by observing when the number of bytes returned is

+
+Compresses and flushes to the compressed file all data so far supplied

+
+If @code{BZ2_bzWriteClose} is called to clean up after an error, the only
+action is to release the memory. The library records the error codes
+issued by previous calls, so this situation will be detected

+
+@subsection Handling embedded compressed data streams
+
+The high-level library facilitates use of
+@code{bzip2} data streams which form some part of a surrounding, larger
+data stream.
+@itemize @bullet
+@item For writing, the library takes an open file handle, writes
+compressed data to it, @code{fflush}es it but does not @code{fclose} it.
+The calling application can write its own data before and after the
+compressed data stream, using that same file handle.
+@item Reading is more complex, and the facilities are not as general
+as they could be since generality is hard to reconcile with efficiency.
+@code{BZ2_bzRead} reads from the compressed file in blocks of size
+@code{BZ_MAX_UNUSED} bytes, and in doing so probably will overshoot
+the logical end of compressed stream.
+To recover this data once decompression has
+ended, call @code{BZ2_bzReadGetUnused} after the last call of @code{BZ2_bzRead}
+(the one returning @code{BZ_STREAM_END}) but before calling
+@code{BZ2_bzReadClose}.
+@end itemize
+
+This mechanism makes it easy to decompress multiple @code{bzip2}
+streams placed end-to-end. As the end of one stream, when @code{BZ2_bzRead}
+returns @code{BZ_STREAM_END}, call @code{BZ2_bzReadGetUnused} to collect the
+unused data (copy it into your own buffer somewhere).
+That data forms the start of the next compressed stream.
+To start uncompressing that next stream, call @code{BZ2_bzReadOpen} again,
+feeding in the unused data via the @code{unused}/@code{nUnused}
+parameters.
+Keep doing this until @code{BZ_STREAM_END} return coincides with the
+physical end of file (@code{feof(f)}). In this situation
+@code{BZ2_bzReadGetUnused}
+will of course return no data.
+
+This should give some feel for how the high-level interface can be used.
+If you require extra flexibility, you'll have to bite the bullet and get
+to grips with the low-level interface.
+
+@subsection Standard file-reading/writing code
+Here's how you'd write data to a compressed file:
+@example @code
+FILE* f;
+BZFILE* b;
+int nBuf;
+char buf[ /* whatever size you like */ ];
+int bzerror;
+int nWritten;
+
+f = fopen ( "myfile.bz2", "w" );
+if (!f) @{
+ /* handle error */
+@}
+b = BZ2_bzWriteOpen ( &bzerror, f, 9 );
+if (bzerror != BZ_OK) @{
+ BZ2_bzWriteClose ( b );
+ /* handle error */
+@}
+
+while ( /* condition */ ) @{
+ /* get data to write into buf, and set nBuf appropriately */
+ nWritten = BZ2_bzWrite ( &bzerror, b, buf, nBuf );
+ if (bzerror == BZ_IO_ERROR) @{
+ BZ2_bzWriteClose ( &bzerror, b );
+ /* handle error */
+ @}
+@}
+
+BZ2_bzWriteClose ( &bzerror, b );
+if (bzerror == BZ_IO_ERROR) @{
+ /* handle error */
+@}
+@end example
+And to read from a compressed file:
+@example
+FILE* f;
+BZFILE* b;
+int nBuf;
+char buf[ /* whatever size you like */ ];
+int bzerror;
+int nWritten;
+
+f = fopen ( "myfile.bz2", "r" );
+if (!f) @{
+ /* handle error */
+@}
+b = BZ2_bzReadOpen ( &bzerror, f, 0, NULL, 0 );
+if (bzerror != BZ_OK) @{
+ BZ2_bzReadClose ( &bzerror, b );
+ /* handle error */
+@}
+
+bzerror = BZ_OK;
+while (bzerror == BZ_OK && /* arbitrary other conditions */) @{
+ nBuf = BZ2_bzRead ( &bzerror, b, buf, /* size of buf */ );
+ if (bzerror == BZ_OK) @{
+ /* do something with buf[0 .. nBuf-1] */
+ @}
+@}
+if (bzerror != BZ_STREAM_END) @{
+ BZ2_bzReadClose ( &bzerror, b );
+ /* handle error */
+@} else @{
+ BZ2_bzReadClose ( &bzerror );
+@}
+@end example
+

+@section @code{zlib} compatibility functions
+Yoshioka Tsuneo has contributed some functions to

+@code{BZ2_bzopen}, @code{BZ2_bzread}, @code{BZ2_bzwrite}, @code{BZ2_bzflush},
+@code{BZ2_bzclose},
+@code{BZ2_bzerror} and @code{BZ2_bzlibVersion}.
+These functions are not (yet) officially part of
+the library. If they break, you get to keep all the pieces.
+Nevertheless, I think they work ok.
+@example
+typedef void BZFILE;
+
+const char * BZ2_bzlibVersion ( void );
+@end example
+Returns a string indicating the library version.
+@example
+BZFILE * BZ2_bzopen ( const char *path, const char *mode );
+BZFILE * BZ2_bzdopen ( int fd, const char *mode );
+@end example
+Opens a @code{.bz2} file for reading or writing, using either its name
+or a pre-existing file descriptor.
+Analogous to @code{fopen} and @code{fdopen}.
+@example
+int BZ2_bzread ( BZFILE* b, void* buf, int len );
+int BZ2_bzwrite ( BZFILE* b, void* buf, int len );
+@end example
+Reads/writes data from/to a previously opened @code{BZFILE}.
+Analogous to @code{fread} and @code{fwrite}.
+@example
+int BZ2_bzflush ( BZFILE* b );
+void BZ2_bzclose ( BZFILE* b );
+@end example
+Flushes/closes a @code{BZFILE}. @code{BZ2_bzflush} doesn't actually do
+anything. Analogous to @code{fflush} and @code{fclose}.
+
+@example
+const char * BZ2_bzerror ( BZFILE *b, int *errnum )
+@end example
+Returns a string describing the more recent error status of
+@code{b}, and also sets @code{*errnum} to its numerical value.
+
+
+@section Using the library in a @code{stdio}-free environment
+
+@subsection Getting rid of @code{stdio}
+
+In a deeply embedded application, you might want to use just
+the memory-to-memory functions. You can do this conveniently
+by compiling the library with preprocessor symbol @code{BZ_NO_STDIO}
+defined. Doing this gives you a library containing only the following
+eight functions:
+
+@code{BZ2_bzCompressInit}, @code{BZ2_bzCompress}, @code{BZ2_bzCompressEnd} @*
+@code{BZ2_bzDecompressInit}, @code{BZ2_bzDecompress}, @code{BZ2_bzDecompressEnd} @*
+@code{BZ2_bzBuffToBuffCompress}, @code{BZ2_bzBuffToBuffDecompress}
+
+When compiled like this, all functions will ignore @code{verbosity}
+settings.
+
+@subsection Critical error handling
+@code{libbzip2} contains a number of internal assertion checks which
+should, needless to say, never be activated. Nevertheless, if an
+assertion should fail, behaviour depends on whether or not the library
+was compiled with @code{BZ_NO_STDIO} set.
+
+For a normal compile, an assertion failure yields the message
+@example
+ bzip2/libbzip2: internal error number N.
+ This is a bug in bzip2/libbzip2, 1.0 of 21-Mar-2000.
+ Please report it to me at: jseward@@acm.org. If this happened
+ when you were using some program which uses libbzip2 as a
+ component, you should also report this bug to the author(s)
+ of that program. Please make an effort to report this bug;
+ timely and accurate bug reports eventually lead to higher
+ quality software. Thanks. Julian Seward, 21 March 2000.
+@end example
+where @code{N} is some error code number. @code{exit(3)}
+is then called.
+
+For a @code{stdio}-free library, assertion failures result
+in a call to a function declared as:
+@example
+ extern void bz_internal_error ( int errcode );
+@end example
+The relevant code is passed as a parameter. You should supply
+such a function.
+
+In either case, once an assertion failure has occurred, any
+@code{bz_stream} records involved can be regarded as invalid.
+You should not attempt to resume normal operation with them.
+
+You may, of course, change critical error handling to suit
+your needs. As I said above, critical errors indicate bugs
+in the library and should not occur. All "normal" error
+situations are indicated via error return codes from functions,
+and can be recovered from.

+@section Making a Windows DLL
+Everything related to Windows has been contributed by Yoshioka Tsuneo
+@* (@code{QWF00133@@niftyserve.or.jp} /
+@code{tsuneo-y@@is.aist-nara.ac.jp}), so you should send your queries to
+him (but perhaps Cc: me, @code{jseward@@acm.org}).
+
+My vague understanding of what to do is: using Visual C++ 5.0,
+open the project file @code{libbz2.dsp}, and build. That's all.
+
+If you can't
+open the project file for some reason, make a new one, naming these files:
+@code{blocksort.c}, @code{bzlib.c}, @code{compress.c},
+@code{crctable.c}, @code{decompress.c}, @code{huffman.c}, @*
+@code{randtable.c} and @code{libbz2.def}. You will also need
+to name the header files @code{bzlib.h} and @code{bzlib_private.h}.
+
+If you don't use VC++, you may need to define the proprocessor symbol
+@code{_WIN32}.
+
+Finally, @code{dlltest.c} is a sample program using the DLL. It has a
+project file, @code{dlltest.dsp}.
+
+If you just want a makefile for Visual C, have a look at
+@code{makefile.msc}.
+
+Be aware that if you compile @code{bzip2} itself on Win32, you must set
+@code{BZ_UNIX} to 0 and @code{BZ_LCCWIN32} to 1, in the file
+@code{bzip2.c}, before compiling. Otherwise the resulting binary won't
+work correctly.
+
+I haven't tried any of this stuff myself, but it all looks plausible.
+
+
+
+@chapter Miscellanea
+
+These are just some random thoughts of mine. Your mileage may
+vary.
+
+@section Limitations of the compressed file format
+@code{bzip2-1.0}, @code{0.9.5} and @code{0.9.0}
+use exactly the same file format as the previous
+version, @code{bzip2-0.1}. This decision was made in the interests of
+stability. Creating yet another incompatible compressed file format
+would create further confusion and disruption for users.
+
+Nevertheless, this is not a painless decision. Development
+work since the release of @code{bzip2-0.1} in August 1997
+has shown complexities in the file format which slow down
+decompression and, in retrospect, are unnecessary. These are:
+@itemize @bullet
+@item The run-length encoder, which is the first of the
+ compression transformations, is entirely irrelevant.
+ The original purpose was to protect the sorting algorithm
+ from the very worst case input: a string of repeated
+ symbols. But algorithm steps Q6a and Q6b in the original
+ Burrows-Wheeler technical report (SRC-124) show how
+ repeats can be handled without difficulty in block
+ sorting.
+@item The randomisation mechanism doesn't really need to be
+ there. Udi Manber and Gene Myers published a suffix
+ array construction algorithm a few years back, which
+ can be employed to sort any block, no matter how
+ repetitive, in O(N log N) time. Subsequent work by
+ Kunihiko Sadakane has produced a derivative O(N (log N)^2)
+ algorithm which usually outperforms the Manber-Myers
+ algorithm.
+
+ I could have changed to Sadakane's algorithm, but I find
+ it to be slower than @code{bzip2}'s existing algorithm for
+ most inputs, and the randomisation mechanism protects
+ adequately against bad cases. I didn't think it was
+ a good tradeoff to make. Partly this is due to the fact
+ that I was not flooded with email complaints about
+ @code{bzip2-0.1}'s performance on repetitive data, so
+ perhaps it isn't a problem for real inputs.
+
+ Probably the best long-term solution,
+ and the one I have incorporated into 0.9.5 and above,
+ is to use the existing sorting
+ algorithm initially, and fall back to a O(N (log N)^2)
+ algorithm if the standard algorithm gets into difficulties.
+@item The compressed file format was never designed to be
+ handled by a library, and I have had to jump though
+ some hoops to produce an efficient implementation of
+ decompression. It's a bit hairy. Try passing
+ @code{decompress.c} through the C preprocessor
+ and you'll see what I mean. Much of this complexity
+ could have been avoided if the compressed size of
+ each block of data was recorded in the data stream.
+@item An Adler-32 checksum, rather than a CRC32 checksum,
+ would be faster to compute.
+@end itemize
+It would be fair to say that the @code{bzip2} format was frozen
+before I properly and fully understood the performance
+consequences of doing so.
+
+Improvements which I was able to incorporate into
+0.9.0, despite using the same file format, are:
+@itemize @bullet
+@item Single array implementation of the inverse BWT. This
+ significantly speeds up decompression, presumably
+ because it reduces the number of cache misses.
+@item Faster inverse MTF transform for large MTF values. The
+ new implementation is based on the notion of sliding blocks
+ of values.
+@item @code{bzip2-0.9.0} now reads and writes files with @code{fread}
+ and @code{fwrite}; version 0.1 used @code{putc} and @code{getc}.
+ Duh! Well, you live and learn.
+
+@end itemize
+Further ahead, it would be nice
+to be able to do random access into files. This will
+require some careful design of compressed file formats.
+
+
+
+@section Portability issues
+After some consideration, I have decided not to use
+GNU @code{autoconf} to configure 0.9.5 or 1.0.
+
+@code{autoconf}, admirable and wonderful though it is,
+mainly assists with portability problems between Unix-like
+platforms. But @code{bzip2} doesn't have much in the way
+of portability problems on Unix; most of the difficulties appear
+when porting to the Mac, or to Microsoft's operating systems.
+@code{autoconf} doesn't help in those cases, and brings in a
+whole load of new complexity.
+
+Most people should be able to compile the library and program
+under Unix straight out-of-the-box, so to speak, especially
+if you have a version of GNU C available.
+
+There are a couple of @code{__inline__} directives in the code. GNU C
+(@code{gcc}) should be able to handle them. If you're not using
+GNU C, your C compiler shouldn't see them at all.
+If your compiler does, for some reason, see them and doesn't
+like them, just @code{#define} @code{__inline__} to be @code{/* */}. One
+easy way to do this is to compile with the flag @code{-D__inline__=},
+which should be understood by most Unix compilers.
+
+If you still have difficulties, try compiling with the macro
+@code{BZ_STRICT_ANSI} defined. This should enable you to build the
+library in a strictly ANSI compliant environment. Building the program
+itself like this is dangerous and not supported, since you remove
+@code{bzip2}'s checks against compressing directories, symbolic links,
+devices, and other not-really-a-file entities. This could cause
+filesystem corruption!
+
+One other thing: if you create a @code{bzip2} binary for public
+distribution, please try and link it statically (@code{gcc -s}). This
+avoids all sorts of library-version issues that others may encounter
+later on.
+
+If you build @code{bzip2} on Win32, you must set @code{BZ_UNIX} to 0 and
+@code{BZ_LCCWIN32} to 1, in the file @code{bzip2.c}, before compiling.
+Otherwise the resulting binary won't work correctly.
+
+
+
+@section Reporting bugs
+I tried pretty hard to make sure @code{bzip2} is
+bug free, both by design and by testing. Hopefully
+you'll never need to read this section for real.
+
+Nevertheless, if @code{bzip2} dies with a segmentation
+fault, a bus error or an internal assertion failure, it
+will ask you to email me a bug report. Experience with
+version 0.1 shows that almost all these problems can
+be traced to either compiler bugs or hardware problems.
+@itemize @bullet
+@item
+Recompile the program with no optimisation, and see if it
+works. And/or try a different compiler.
+I heard all sorts of stories about various flavours
+of GNU C (and other compilers) generating bad code for
+@code{bzip2}, and I've run across two such examples myself.
+
+2.7.X versions of GNU C are known to generate bad code from
+time to time, at high optimisation levels.
+If you get problems, try using the flags
+@code{-O2} @code{-fomit-frame-pointer} @code{-fno-strength-reduce}.
+You should specifically @emph{not} use @code{-funroll-loops}.
+
+You may notice that the Makefile runs six tests as part of
+the build process. If the program passes all of these, it's
+a pretty good (but not 100%) indication that the compiler has
+done its job correctly.
+@item
+If @code{bzip2} crashes randomly, and the crashes are not
+repeatable, you may have a flaky memory subsystem. @code{bzip2}
+really hammers your memory hierarchy, and if it's a bit marginal,
+you may get these problems. Ditto if your disk or I/O subsystem
+is slowly failing. Yup, this really does happen.
+
+Try using a different machine of the same type, and see if
+you can repeat the problem.
+@item This isn't really a bug, but ... If @code{bzip2} tells
+you your file is corrupted on decompression, and you
+obtained the file via FTP, there is a possibility that you
+forgot to tell FTP to do a binary mode transfer. That absolutely
+will cause the file to be non-decompressible. You'll have to transfer
+it again.
+@end itemize
+
+If you've incorporated @code{libbzip2} into your own program
+and are getting problems, please, please, please, check that the
+parameters you are passing in calls to the library, are
+correct, and in accordance with what the documentation says
+is allowable. I have tried to make the library robust against
+such problems, but I'm sure I haven't succeeded.
+
+Finally, if the above comments don't help, you'll have to send
+me a bug report. Now, it's just amazing how many people will
+send me a bug report saying something like
+@display
+ bzip2 crashed with segmentation fault on my machine
+@end display
+and absolutely nothing else. Needless to say, a such a report
+is @emph{totally, utterly, completely and comprehensively 100% useless;
+a waste of your time, my time, and net bandwidth}.
+With no details at all, there's no way I can possibly begin
+to figure out what the problem is.
+
+The rules of the game are: facts, facts, facts. Don't omit
+them because "oh, they won't be relevant". At the bare
+minimum:
+@display
+ Machine type. Operating system version.
+ Exact version of @code{bzip2} (do @code{bzip2 -V}).
+ Exact version of the compiler used.
+ Flags passed to the compiler.
+@end display
+However, the most important single thing that will help me is
+the file that you were trying to compress or decompress at the
+time the problem happened. Without that, my ability to do anything
+more than speculate about the cause, is limited.
+
+Please remember that I connect to the Internet with a modem, so
+you should contact me before mailing me huge files.
+
+
+@section Did you get the right package?
+
+@code{bzip2} is a resource hog. It soaks up large amounts of CPU cycles
+and memory. Also, it gives very large latencies. In the worst case, you
+can feed many megabytes of uncompressed data into the library before
+getting any compressed output, so this probably rules out applications
+requiring interactive behaviour.
+
+These aren't faults of my implementation, I hope, but more
+an intrinsic property of the Burrows-Wheeler transform (unfortunately).
+Maybe this isn't what you want.
+
+If you want a compressor and/or library which is faster, uses less
+memory but gets pretty good compression, and has minimal latency,
+consider Jean-loup
+Gailly's and Mark Adler's work, @code{zlib-1.1.2} and
+@code{gzip-1.2.4}. Look for them at
+
+@code{http://www.cdrom.com/pub/infozip/zlib} and
+@code{http://www.gzip.org} respectively.
+
+For something faster and lighter still, you might try Markus F X J
+Oberhumer's @code{LZO} real-time compression/decompression library, at
+@* @code{http://wildsau.idv.uni-linz.ac.at/mfx/lzo.html}.
+
+If you want to use the @code{bzip2} algorithms to compress small blocks
+of data, 64k bytes or smaller, for example on an on-the-fly disk
+compressor, you'd be well advised not to use this library. Instead,
+I've made a special library tuned for that kind of use. It's part of
+@code{e2compr-0.40}, an on-the-fly disk compressor for the Linux
+@code{ext2} filesystem. Look at
+@code{http://www.netspace.net.au/~reiter/e2compr}.
+
+
+
+@section Testing
+
+A record of the tests I've done.
+
+First, some data sets:
+@itemize @bullet
+@item B: a directory containing 6001 files, one for every length in the
+ range 0 to 6000 bytes. The files contain random lowercase
+ letters. 18.7 megabytes.
+@item H: my home directory tree. Documents, source code, mail files,
+ compressed data. H contains B, and also a directory of
+ files designed as boundary cases for the sorting; mostly very
+ repetitive, nasty files. 565 megabytes.
+@item A: directory tree holding various applications built from source:
+ @code{egcs}, @code{gcc-2.8.1}, KDE, GTK, Octave, etc.
+ 2200 megabytes.
+@end itemize
+The tests conducted are as follows. Each test means compressing
+(a copy of) each file in the data set, decompressing it and
+comparing it against the original.
+
+First, a bunch of tests with block sizes and internal buffer
+sizes set very small,
+to detect any problems with the
+blocking and buffering mechanisms.
+This required modifying the source code so as to try to
+break it.
+@enumerate
+@item Data set H, with
+ buffer size of 1 byte, and block size of 23 bytes.
+@item Data set B, buffer sizes 1 byte, block size 1 byte.
+@item As (2) but small-mode decompression.
+@item As (2) with block size 2 bytes.
+@item As (2) with block size 3 bytes.
+@item As (2) with block size 4 bytes.
+@item As (2) with block size 5 bytes.
+@item As (2) with block size 6 bytes and small-mode decompression.
+@item H with buffer size of 1 byte, but normal block
+ size (up to 900000 bytes).
+@end enumerate
+Then some tests with unmodified source code.
+@enumerate
+@item H, all settings normal.
+@item As (1), with small-mode decompress.
+@item H, compress with flag @code{-1}.
+@item H, compress with flag @code{-s}, decompress with flag @code{-s}.
+@item Forwards compatibility: H, @code{bzip2-0.1pl2} compressing,
+ @code{bzip2-0.9.5} decompressing, all settings normal.
+@item Backwards compatibility: H, @code{bzip2-0.9.5} compressing,
+ @code{bzip2-0.1pl2} decompressing, all settings normal.
+@item Bigger tests: A, all settings normal.
+@item As (7), using the fallback (Sadakane-like) sorting algorithm.
+@item As (8), compress with flag @code{-1}, decompress with flag
+ @code{-s}.
+@item H, using the fallback sorting algorithm.
+@item Forwards compatibility: A, @code{bzip2-0.1pl2} compressing,
+ @code{bzip2-0.9.5} decompressing, all settings normal.
+@item Backwards compatibility: A, @code{bzip2-0.9.5} compressing,
+ @code{bzip2-0.1pl2} decompressing, all settings normal.
+@item Misc test: about 400 megabytes of @code{.tar} files with
+ @code{bzip2} compiled with Checker (a memory access error
+ detector, like Purify).
+@item Misc tests to make sure it builds and runs ok on non-Linux/x86
+ platforms.
+@end enumerate
+These tests were conducted on a 225 MHz IDT WinChip machine, running
+Linux 2.0.36. They represent nearly a week of continuous computation.
+All tests completed successfully.
+
+
+@section Further reading
+@code{bzip2} is not research work, in the sense that it doesn't present
+any new ideas. Rather, it's an engineering exercise based on existing
+ideas.
+
+Four documents describe essentially all the ideas behind @code{bzip2}:
+@example
+Michael Burrows and D. J. Wheeler:
+ "A block-sorting lossless data compression algorithm"
+ 10th May 1994.
+ Digital SRC Research Report 124.
+ ftp://ftp.digital.com/pub/DEC/SRC/research-reports/SRC-124.ps.gz
+ If you have trouble finding it, try searching at the
+ New Zealand Digital Library, http://www.nzdl.org.
+
+Daniel S. Hirschberg and Debra A. LeLewer
+ "Efficient Decoding of Prefix Codes"
+ Communications of the ACM, April 1990, Vol 33, Number 4.
+ You might be able to get an electronic copy of this
+ from the ACM Digital Library.
+
+David J. Wheeler
+ Program bred3.c and accompanying document bred3.ps.
+ This contains the idea behind the multi-table Huffman
+ coding scheme.
+ ftp://ftp.cl.cam.ac.uk/users/djw3/
+
+Jon L. Bentley and Robert Sedgewick
+ "Fast Algorithms for Sorting and Searching Strings"
+ Available from Sedgewick's web page,
+ www.cs.princeton.edu/~rs
+@end example
+The following paper gives valuable additional insights into the
+algorithm, but is not immediately the basis of any code
+used in bzip2.
+@example
+Peter Fenwick:
+ Block Sorting Text Compression
+ Proceedings of the 19th Australasian Computer Science Conference,
+ Melbourne, Australia. Jan 31 - Feb 2, 1996.
+ ftp://ftp.cs.auckland.ac.nz/pub/peter-f/ACSC96paper.ps
+@end example
+Kunihiko Sadakane's sorting algorithm, mentioned above,
+is available from:
+@example
+http://naomi.is.s.u-tokyo.ac.jp/~sada/papers/Sada98b.ps.gz
+@end example
+The Manber-Myers suffix array construction
+algorithm is described in a paper
+available from:
+@example
+http://www.cs.arizona.edu/people/gene/PAPERS/suffix.ps
+@end example
+Finally, the following paper documents some recent investigations
+I made into the performance of sorting algorithms:
+@example
+Julian Seward:
+ On the Performance of BWT Sorting Algorithms
+ Proceedings of the IEEE Data Compression Conference 2000
+ Snowbird, Utah. 28-30 March 2000.

+<CODE>bzip2</CODE> compresses files using the Burrows-Wheeler block sorting
+text compression algorithm, and Huffman coding. Compression is
+generally considerably better than that achieved by more conventional
+LZ77/LZ78-based compressors, and approaches the performance of the PPM
+family of statistical compressors.
+
+</P>
+<P>
+The command-line options are deliberately very similar to those of GNU
+<CODE>gzip</CODE>, but they are not identical.
+
+</P>
+<P>
+<CODE>bzip2</CODE> expects a list of file names to accompany the command-line
+flags. Each file is replaced by a compressed version of itself, with
+the name <CODE>original_name.bz2</CODE>. Each compressed file has the same
+modification date, permissions, and, when possible, ownership as the
+corresponding original, so that these properties can be correctly
+restored at decompression time. File name handling is naive in the
+sense that there is no mechanism for preserving original file names,
+permissions, ownerships or dates in filesystems which lack these
+concepts, or have serious file name length restrictions, such as MS-DOS.
+
+</P>
+<P>
+<CODE>bzip2</CODE> and <CODE>bunzip2</CODE> will by default not overwrite existing
+files. If you want this to happen, specify the <CODE>-f</CODE> flag.
+
+</P>
+<P>
+If no file names are specified, <CODE>bzip2</CODE> compresses from standard
+input to standard output. In this case, <CODE>bzip2</CODE> will decline to
+write compressed output to a terminal, as this would be entirely
+incomprehensible and therefore pointless.
+
+</P>
+<P>
+<CODE>bunzip2</CODE> (or <CODE>bzip2 -d</CODE>) decompresses all
+specified files. Files which were not created by <CODE>bzip2</CODE>
+will be detected and ignored, and a warning issued.
+<CODE>bzip2</CODE> attempts to guess the filename for the decompressed file
+from that of the compressed file as follows:
+
+<UL>
+<LI><CODE>filename.bz2 </CODE> becomes <CODE>filename</CODE>
+
+<LI><CODE>filename.bz </CODE> becomes <CODE>filename</CODE>
+
+<LI><CODE>filename.tbz2</CODE> becomes <CODE>filename.tar</CODE>
+
+<LI><CODE>filename.tbz </CODE> becomes <CODE>filename.tar</CODE>
+
+<LI><CODE>anyothername </CODE> becomes <CODE>anyothername.out</CODE>
+
+</UL>
+
+<P>
+If the file does not end in one of the recognised endings,
+<CODE>.bz2</CODE>, <CODE>.bz</CODE>,
+<CODE>.tbz2</CODE> or <CODE>.tbz</CODE>, <CODE>bzip2</CODE> complains that it cannot
+guess the name of the original file, and uses the original name
+with <CODE>.out</CODE> appended.
+
+</P>
+<P>
+As with compression, supplying no
+filenames causes decompression from standard input to standard output.
+
+</P>
+<P>
+<CODE>bunzip2</CODE> will correctly decompress a file which is the
+concatenation of two or more compressed files. The result is the
+concatenation of the corresponding uncompressed files. Integrity
+testing (<CODE>-t</CODE>) of concatenated compressed files is also supported.
+
+</P>
+<P>
+You can also compress or decompress files to the standard output by
+giving the <CODE>-c</CODE> flag. Multiple files may be compressed and
+decompressed like this. The resulting outputs are fed sequentially to
+stdout. Compression of multiple files in this manner generates a stream
+containing multiple compressed file representations. Such a stream
+can be decompressed correctly only by <CODE>bzip2</CODE> version 0.9.0 or
+later. Earlier versions of <CODE>bzip2</CODE> will stop after decompressing
+the first file in the stream.
+
+</P>
+<P>
+<CODE>bzcat</CODE> (or <CODE>bzip2 -dc</CODE>) decompresses all specified files to
+the standard output.
+
+</P>
+<P>
+<CODE>bzip2</CODE> will read arguments from the environment variables
+<CODE>BZIP2</CODE> and <CODE>BZIP</CODE>, in that order, and will process them
+before any arguments read from the command line. This gives a
+convenient way to supply default arguments.
+
+</P>
+<P>
+Compression is always performed, even if the compressed file is slightly
+larger than the original. Files of less than about one hundred bytes
+tend to get larger, since the compression mechanism has a constant
+overhead in the region of 50 bytes. Random data (including the output
+of most file compressors) is coded at about 8.05 bits per byte, giving
+an expansion of around 0.5%.
+
+</P>
+<P>
+As a self-check for your protection, <CODE>bzip2</CODE> uses 32-bit CRCs to
+make sure that the decompressed version of a file is identical to the
+original. This guards against corruption of the compressed data, and
+against undetected bugs in <CODE>bzip2</CODE> (hopefully very unlikely). The
+chances of data corruption going undetected is microscopic, about one
+chance in four billion for each file processed. Be aware, though, that
+the check occurs upon decompression, so it can only tell you that
+something is wrong. It can't help you recover the original uncompressed
+data. You can use <CODE>bzip2recover</CODE> to try to recover data from
+damaged files.
+
+</P>
+<P>
+Return values: 0 for a normal exit, 1 for environmental problems (file
+not found, invalid flags, I/O errors, &#38;c), 2 to indicate a corrupt
+compressed file, 3 for an internal consistency error (eg, bug) which
+caused <CODE>bzip2</CODE> to panic.

+Compress or decompress to standard output.

+<DD>
+Force decompression. <CODE>bzip2</CODE>, <CODE>bunzip2</CODE> and <CODE>bzcat</CODE> are

+<DT><CODE>-t --test</CODE>
+<DD>
+Check integrity of the specified file(s), but don't decompress them.
+This really performs a trial decompression and throws away the result.
+<DT><CODE>-f --force</CODE>
+<DD>
+Force overwrite of output files. Normally, <CODE>bzip2</CODE> will not overwrite
+existing output files. Also forces <CODE>bzip2</CODE> to break hard links
+to files, which it otherwise wouldn't do.

+<DD>
+Keep (don't delete) input files during compression
+or decompression.
+<DT><CODE>-s --small</CODE>
+<DD>
+Reduce memory usage, for compression, decompression and testing. Files
+are decompressed and tested using a modified algorithm which only
+requires 2.5 bytes per block byte. This means any file can be
+decompressed in 2300k of memory, albeit at about half the normal speed.

+During compression, <CODE>-s</CODE> selects a block size of 200k, which limits
+memory use to around the same figure, at the expense of your compression
+ratio. In short, if your machine is low on memory (8 megabytes or
+less), use -s for everything. See MEMORY MANAGEMENT below.

+These flags are redundant in versions 0.9.5 and above. They provided

+
+<H4><A NAME="SEC7" HREF="manual_toc.html#TOC7">MEMORY MANAGEMENT</A></H4>
+
+<P>
+<CODE>bzip2</CODE> compresses large files in blocks. The block size affects
+both the compression ratio achieved, and the amount of memory needed for
+compression and decompression. The flags <CODE>-1</CODE> through <CODE>-9</CODE>
+specify the block size to be 100,000 bytes through 900,000 bytes (the
+default) respectively. At decompression time, the block size used for
+compression is read from the header of the compressed file, and
+<CODE>bunzip2</CODE> then allocates itself just enough memory to decompress
+the file. Since block sizes are stored in compressed files, it follows
+that the flags <CODE>-1</CODE> to <CODE>-9</CODE> are irrelevant to and so ignored
+during decompression.
+
+</P>
+<P>
+Compression and decompression requirements, in bytes, can be estimated
+as:
+
+<PRE>
+ Compression: 400k + ( 8 x block size )
+
+ Decompression: 100k + ( 4 x block size ), or
+ 100k + ( 2.5 x block size )
+</PRE>
+
+<P>
+Larger block sizes give rapidly diminishing marginal returns. Most of
+the compression comes from the first two or three hundred k of block
+size, a fact worth bearing in mind when using <CODE>bzip2</CODE> on small machines.
+It is also important to appreciate that the decompression memory
+requirement is set at compression time by the choice of block size.
+
+</P>
+<P>
+For files compressed with the default 900k block size, <CODE>bunzip2</CODE>
+will require about 3700 kbytes to decompress. To support decompression
+of any file on a 4 megabyte machine, <CODE>bunzip2</CODE> has an option to
+decompress using approximately half this amount of memory, about 2300
+kbytes. Decompression speed is also halved, so you should use this
+option only where necessary. The relevant flag is <CODE>-s</CODE>.
+
+</P>
+<P>
+In general, try and use the largest block size memory constraints allow,
+since that maximises the compression achieved. Compression and
+decompression speed are virtually unaffected by block size.
+
+</P>
+<P>
+Another significant point applies to files which fit in a single block
+-- that means most files you'd encounter using a large block size. The
+amount of real memory touched is proportional to the size of the file,
+since the file is smaller than a block. For example, compressing a file
+20,000 bytes long with the flag <CODE>-9</CODE> will cause the compressor to
+allocate around 7600k of memory, but only touch 400k + 20000 * 8 = 560
+kbytes of it. Similarly, the decompressor will allocate 3700k but only
+touch 100k + 20000 * 4 = 180 kbytes.
+
+</P>
+<P>
+Here is a table which summarises the maximum memory usage for different
+block sizes. Also recorded is the total compressed size for 14 files of
+the Calgary Text Compression Corpus totalling 3,141,622 bytes. This
+column gives some feel for how compression varies with block size.
+These figures tend to understate the advantage of larger block sizes for
+larger files, since the Corpus is dominated by smaller files.

+
+<P>
+<CODE>bzip2</CODE> compresses files in blocks, usually 900kbytes long. Each
+block is handled independently. If a media or transmission error causes
+a multi-block <CODE>.bz2</CODE> file to become damaged, it may be possible to
+recover data from the undamaged blocks in the file.
+
+</P>
+<P>
+The compressed representation of each block is delimited by a 48-bit
+pattern, which makes it possible to find the block boundaries with
+reasonable certainty. Each block also carries its own 32-bit CRC, so
+damaged blocks can be distinguished from undamaged ones.
+
+</P>
+<P>
+<CODE>bzip2recover</CODE> is a simple program whose purpose is to search for
+blocks in <CODE>.bz2</CODE> files, and write each block out into its own
+<CODE>.bz2</CODE> file. You can then use <CODE>bzip2 -t</CODE> to test the
+integrity of the resulting files, and decompress those which are
+undamaged.
+
+</P>
+<P>
+<CODE>bzip2recover</CODE>
+takes a single argument, the name of the damaged file,
+and writes a number of files <CODE>rec0001file.bz2</CODE>,

+ The output filenames are designed so that the use of
+ wildcards in subsequent processing -- for example,
+<CODE>bzip2 -dc rec*file.bz2 &#62; recovered_data</CODE> -- lists the files in
+ the correct order.
+
+</P>
+<P>
+<CODE>bzip2recover</CODE> should be of most use dealing with large <CODE>.bz2</CODE>
+ files, as these will contain many blocks. It is clearly
+ futile to use it on damaged single-block files, since a
+ damaged block cannot be recovered. If you wish to minimise
+any potential data loss through media or transmission errors,
+you might consider compressing with a smaller
+ block size.

+
+<H4><A NAME="SEC9" HREF="manual_toc.html#TOC9">PERFORMANCE NOTES</A></H4>
+
+<P>
+The sorting phase of compression gathers together similar strings in the
+file. Because of this, files containing very long runs of repeated
+symbols, like "aabaabaabaab ..." (repeated several hundred times) may
+compress more slowly than normal. Versions 0.9.5 and above fare much
+better than previous versions in this respect. The ratio between
+worst-case and average-case compression time is in the region of 10:1.
+For previous versions, this figure was more like 100:1. You can use the
+<CODE>-vvvv</CODE> option to monitor progress in great detail, if you want.
+
+</P>
+<P>
+Decompression speed is unaffected by these phenomena.
+
+</P>
+<P>
+<CODE>bzip2</CODE> usually allocates several megabytes of memory to operate
+in, and then charges all over it in a fairly random fashion. This means
+that performance, both for compressing and decompressing, is largely
+determined by the speed at which your machine can service cache misses.
+Because of this, small changes to the code to reduce the miss rate have
+been observed to give disproportionately large performance improvements.
+I imagine <CODE>bzip2</CODE> will perform best on machines with very large
+caches.

+<P>
+I/O error messages are not as helpful as they could be. <CODE>bzip2</CODE>
+tries hard to detect I/O errors and exit cleanly, but the details of
+what the problem is sometimes seem rather misleading.
+
+</P>
+<P>
+This manual page pertains to version 1.0 of <CODE>bzip2</CODE>. Compressed
+data created by this version is entirely forwards and backwards
+compatible with the previous public releases, versions 0.1pl2, 0.9.0 and
+0.9.5, but with the following exception: 0.9.0 and above can correctly
+decompress multiple concatenated compressed files. 0.1pl2 cannot do
+this; it will stop after decompressing just the first file in the
+stream.
+
+</P>
+<P>
+<CODE>bzip2recover</CODE> uses 32-bit integers to represent bit positions in

+The ideas embodied in <CODE>bzip2</CODE> are due to (at least) the following

+von Roques encouraged me to look for faster sorting algorithms, so as to

+
+<P>
+This chapter describes the programming interface to <CODE>libbzip2</CODE>.
+
+</P>
+<P>
+For general background information, particularly about memory
+use and performance aspects, you'd be well advised to read Chapter 2
+as well.
+
+</P>
+
+
+<H2><A NAME="SEC13" HREF="manual_toc.html#TOC13">Top-level structure</A></H2>
+
+<P>
+<CODE>libbzip2</CODE> is a flexible library for compressing and decompressing
+data in the <CODE>bzip2</CODE> data format. Although packaged as a single
+entity, it helps to regard the library as three separate parts: the low
+level interface, and the high level interface, and some utility
+functions.
+
+</P>
+<P>
+The structure of <CODE>libbzip2</CODE>'s interfaces is similar to
+that of Jean-loup Gailly's and Mark Adler's excellent <CODE>zlib</CODE>
+library.
+
+</P>
+<P>
+All externally visible symbols have names beginning <CODE>BZ2_</CODE>.
+This is new in version 1.0. The intention is to minimise pollution
+of the namespaces of library clients.
+
+</P>
+
+
+<H3><A NAME="SEC14" HREF="manual_toc.html#TOC14">Low-level summary</A></H3>
+
+<P>
+This interface provides services for compressing and decompressing
+data in memory. There's no provision for dealing with files, streams
+or any other I/O mechanisms, just straight memory-to-memory work.
+In fact, this part of the library can be compiled without inclusion
+of <CODE>stdio.h</CODE>, which may be helpful for embedded applications.
+
+</P>
+<P>
+The low-level part of the library has no global variables and
+is therefore thread-safe.
+
+</P>
+<P>
+Six routines make up the low level interface:
+<CODE>BZ2_bzCompressInit</CODE>, <CODE>BZ2_bzCompress</CODE>, and <BR> <CODE>BZ2_bzCompressEnd</CODE>
+for compression,
+and a corresponding trio <CODE>BZ2_bzDecompressInit</CODE>, <BR> <CODE>BZ2_bzDecompress</CODE>
+and <CODE>BZ2_bzDecompressEnd</CODE> for decompression.
+The <CODE>*Init</CODE> functions allocate
+memory for compression/decompression and do other
+initialisations, whilst the <CODE>*End</CODE> functions close down operations
+and release memory.
+
+</P>
+<P>
+The real work is done by <CODE>BZ2_bzCompress</CODE> and <CODE>BZ2_bzDecompress</CODE>.
+These compress and decompress data from a user-supplied input buffer
+to a user-supplied output buffer. These buffers can be any size;
+arbitrary quantities of data are handled by making repeated calls
+to these functions. This is a flexible mechanism allowing a
+consumer-pull style of activity, or producer-push, or a mixture of
+both.
+
+</P>
+
+
+
+<H3><A NAME="SEC15" HREF="manual_toc.html#TOC15">High-level summary</A></H3>
+
+<P>
+This interface provides some handy wrappers around the low-level
+interface to facilitate reading and writing <CODE>bzip2</CODE> format
+files (<CODE>.bz2</CODE> files). The routines provide hooks to facilitate
+reading files in which the <CODE>bzip2</CODE> data stream is embedded
+within some larger-scale file structure, or where there are
+multiple <CODE>bzip2</CODE> data streams concatenated end-to-end.
+
+</P>
+<P>
+For reading files, <CODE>BZ2_bzReadOpen</CODE>, <CODE>BZ2_bzRead</CODE>,
+<CODE>BZ2_bzReadClose</CODE> and <BR> <CODE>BZ2_bzReadGetUnused</CODE> are supplied. For
+writing files, <CODE>BZ2_bzWriteOpen</CODE>, <CODE>BZ2_bzWrite</CODE> and
+<CODE>BZ2_bzWriteFinish</CODE> are available.
+
+</P>
+<P>
+As with the low-level library, no global variables are used
+so the library is per se thread-safe. However, if I/O errors
+occur whilst reading or writing the underlying compressed files,
+you may have to consult <CODE>errno</CODE> to determine the cause of
+the error. In that case, you'd need a C library which correctly
+supports <CODE>errno</CODE> in a multithreaded environment.
+
+</P>
+<P>
+To make the library a little simpler and more portable,
+<CODE>BZ2_bzReadOpen</CODE> and <CODE>BZ2_bzWriteOpen</CODE> require you to pass them file
+handles (<CODE>FILE*</CODE>s) which have previously been opened for reading or
+writing respectively. That avoids portability problems associated with
+file operations and file attributes, whilst not being much of an
+imposition on the programmer.
+
+</P>
+
+
+
+<H3><A NAME="SEC16" HREF="manual_toc.html#TOC16">Utility functions summary</A></H3>
+<P>
+For very simple needs, <CODE>BZ2_bzBuffToBuffCompress</CODE> and
+<CODE>BZ2_bzBuffToBuffDecompress</CODE> are provided. These compress
+data in memory from one buffer to another buffer in a single
+function call. You should assess whether these functions
+fulfill your memory-to-memory compression/decompression
+requirements before investing effort in understanding the more
+general but more complex low-level interface.
+
+</P>
+<P>
+Yoshioka Tsuneo (<CODE>QWF00133@niftyserve.or.jp</CODE> /
+<CODE>tsuneo-y@is.aist-nara.ac.jp</CODE>) has contributed some functions to
+give better <CODE>zlib</CODE> compatibility. These functions are
+<CODE>BZ2_bzopen</CODE>, <CODE>BZ2_bzread</CODE>, <CODE>BZ2_bzwrite</CODE>, <CODE>BZ2_bzflush</CODE>,
+<CODE>BZ2_bzclose</CODE>,
+<CODE>BZ2_bzerror</CODE> and <CODE>BZ2_bzlibVersion</CODE>. You may find these functions
+more convenient for simple file reading and writing, than those in the
+high-level interface. These functions are not (yet) officially part of
+the library, and are minimally documented here. If they break, you
+get to keep all the pieces. I hope to document them properly when time
+permits.
+
+</P>
+<P>
+Yoshioka also contributed modifications to allow the library to be
+built as a Windows DLL.
+
+</P>
+
+
+
+<H2><A NAME="SEC17" HREF="manual_toc.html#TOC17">Error handling</A></H2>
+
+<P>
+The library is designed to recover cleanly in all situations, including
+the worst-case situation of decompressing random data. I'm not
+100% sure that it can always do this, so you might want to add
+a signal handler to catch segmentation violations during decompression
+if you are feeling especially paranoid. I would be interested in
+hearing more about the robustness of the library to corrupted
+compressed data.
+
+</P>
+<P>
+Version 1.0 is much more robust in this respect than
+0.9.0 or 0.9.5. Investigations with Checker (a tool for
+detecting problems with memory management, similar to Purify)
+indicate that, at least for the few files I tested, all single-bit
+errors in the decompressed data are caught properly, with no
+segmentation faults, no reads of uninitialised data and no
+out of range reads or writes. So it's certainly much improved,
+although I wouldn't claim it to be totally bombproof.
+
+</P>
+<P>
+The file <CODE>bzlib.h</CODE> contains all definitions needed to use
+the library. In particular, you should definitely not include
+<CODE>bzlib_private.h</CODE>.
+
+</P>
+<P>
+In <CODE>bzlib.h</CODE>, the various return values are defined. The following
+list is not intended as an exhaustive description of the circumstances
+in which a given value may be returned -- those descriptions are given
+later. Rather, it is intended to convey the rough meaning of each
+return value. The first five actions are normal and not intended to
+denote an error situation.
+<DL COMPACT>
+
+<DT><CODE>BZ_OK</CODE>
+<DD>
+The requested action was completed successfully.
+<DT><CODE>BZ_RUN_OK</CODE>
+<DD>
+<DT><CODE>BZ_FLUSH_OK</CODE>
+<DD>
+<DT><CODE>BZ_FINISH_OK</CODE>
+<DD>
+In <CODE>BZ2_bzCompress</CODE>, the requested flush/finish/nothing-special action
+was completed successfully.
+<DT><CODE>BZ_STREAM_END</CODE>
+<DD>
+Compression of data was completed, or the logical stream end was
+detected during decompression.
+</DL>
+
+<P>
+The following return values indicate an error of some kind.
+<DL COMPACT>
+
+<DT><CODE>BZ_CONFIG_ERROR</CODE>
+<DD>
+Indicates that the library has been improperly compiled on your
+platform -- a major configuration error. Specifically, it means
+that <CODE>sizeof(char)</CODE>, <CODE>sizeof(short)</CODE> and <CODE>sizeof(int)</CODE>
+are not 1, 2 and 4 respectively, as they should be. Note that the
+library should still work properly on 64-bit platforms which follow
+the LP64 programming model -- that is, where <CODE>sizeof(long)</CODE>
+and <CODE>sizeof(void*)</CODE> are 8. Under LP64, <CODE>sizeof(int)</CODE> is
+still 4, so <CODE>libbzip2</CODE>, which doesn't use the <CODE>long</CODE> type,
+is OK.
+<DT><CODE>BZ_SEQUENCE_ERROR</CODE>
+<DD>
+When using the library, it is important to call the functions in the
+correct sequence and with data structures (buffers etc) in the correct
+states. <CODE>libbzip2</CODE> checks as much as it can to ensure this is
+happening, and returns <CODE>BZ_SEQUENCE_ERROR</CODE> if not. Code which
+complies precisely with the function semantics, as detailed below,
+should never receive this value; such an event denotes buggy code
+which you should investigate.
+<DT><CODE>BZ_PARAM_ERROR</CODE>
+<DD>
+Returned when a parameter to a function call is out of range
+or otherwise manifestly incorrect. As with <CODE>BZ_SEQUENCE_ERROR</CODE>,
+this denotes a bug in the client code. The distinction between
+<CODE>BZ_PARAM_ERROR</CODE> and <CODE>BZ_SEQUENCE_ERROR</CODE> is a bit hazy, but still worth
+making.
+<DT><CODE>BZ_MEM_ERROR</CODE>
+<DD>
+Returned when a request to allocate memory failed. Note that the
+quantity of memory needed to decompress a stream cannot be determined
+until the stream's header has been read. So <CODE>BZ2_bzDecompress</CODE> and
+<CODE>BZ2_bzRead</CODE> may return <CODE>BZ_MEM_ERROR</CODE> even though some of
+the compressed data has been read. The same is not true for
+compression; once <CODE>BZ2_bzCompressInit</CODE> or <CODE>BZ2_bzWriteOpen</CODE> have
+successfully completed, <CODE>BZ_MEM_ERROR</CODE> cannot occur.
+<DT><CODE>BZ_DATA_ERROR</CODE>
+<DD>
+Returned when a data integrity error is detected during decompression.
+Most importantly, this means when stored and computed CRCs for the
+data do not match. This value is also returned upon detection of any
+other anomaly in the compressed data.
+<DT><CODE>BZ_DATA_ERROR_MAGIC</CODE>
+<DD>
+As a special case of <CODE>BZ_DATA_ERROR</CODE>, it is sometimes useful to
+know when the compressed stream does not start with the correct
+magic bytes (<CODE>'B' 'Z' 'h'</CODE>).
+<DT><CODE>BZ_IO_ERROR</CODE>
+<DD>
+Returned by <CODE>BZ2_bzRead</CODE> and <CODE>BZ2_bzWrite</CODE> when there is an error
+reading or writing in the compressed file, and by <CODE>BZ2_bzReadOpen</CODE>
+and <CODE>BZ2_bzWriteOpen</CODE> for attempts to use a file for which the
+error indicator (viz, <CODE>ferror(f)</CODE>) is set.
+On receipt of <CODE>BZ_IO_ERROR</CODE>, the caller should consult
+<CODE>errno</CODE> and/or <CODE>perror</CODE> to acquire operating-system
+specific information about the problem.
+<DT><CODE>BZ_UNEXPECTED_EOF</CODE>
+<DD>
+Returned by <CODE>BZ2_bzRead</CODE> when the compressed file finishes
+before the logical end of stream is detected.
+<DT><CODE>BZ_OUTBUFF_FULL</CODE>
+<DD>
+Returned by <CODE>BZ2_bzBuffToBuffCompress</CODE> and
+<CODE>BZ2_bzBuffToBuffDecompress</CODE> to indicate that the output data
+will not fit into the output buffer provided.

+all calls to <CODE>bzalloc</CODE> and <CODE>bzfree</CODE>, but is
+otherwise ignored by the library.
+The call <CODE>bzalloc ( opaque, n, m )</CODE> is expected to return a
+pointer <CODE>p</CODE> to
+<CODE>n * m</CODE> bytes of memory, and <CODE>bzfree ( opaque, p )</CODE>
+should free
+that memory.
+
+</P>
+<P>
+If you don't want to use a custom memory allocator, set <CODE>bzalloc</CODE>,
+<CODE>bzfree</CODE> and
+<CODE>opaque</CODE> to <CODE>NULL</CODE>,
+and the library will then use the standard <CODE>malloc</CODE>/<CODE>free</CODE>
+routines.
+
+</P>
+<P>
+Before calling <CODE>BZ2_bzCompressInit</CODE>, fields <CODE>bzalloc</CODE>,
+<CODE>bzfree</CODE> and <CODE>opaque</CODE> should
+be filled appropriately, as just described. Upon return, the internal
+state will have been allocated and initialised, and <CODE>total_in_lo32</CODE>,
+<CODE>total_in_hi32</CODE>, <CODE>total_out_lo32</CODE> and
+<CODE>total_out_hi32</CODE> will have been set to zero.
+These four fields are used by the library
+to inform the caller of the total amount of data passed into and out of
+the library, respectively. You should not try to change them.
+As of version 1.0, 64-bit counts are maintained, even on 32-bit
+platforms, using the <CODE>_hi32</CODE> fields to store the upper 32 bits
+of the count. So, for example, the total amount of data in
+is <CODE>(total_in_hi32 &#60;&#60; 32) + total_in_lo32</CODE>.
+
+</P>
+<P>
+Parameter <CODE>blockSize100k</CODE> specifies the block size to be used for
+compression. It should be a value between 1 and 9 inclusive, and the
+actual block size used is 100000 x this figure. 9 gives the best
+compression but takes most memory.
+
+</P>
+<P>
+Parameter <CODE>verbosity</CODE> should be set to a number between 0 and 4
+inclusive. 0 is silent, and greater numbers give increasingly verbose
+monitoring/debugging output. If the library has been compiled with
+<CODE>-DBZ_NO_STDIO</CODE>, no such output will appear for any verbosity
+setting.
+
+</P>
+<P>
+Parameter <CODE>workFactor</CODE> controls how the compression phase behaves
+when presented with worst case, highly repetitive, input data. If
+compression runs into difficulties caused by repetitive data, the
+library switches from the standard sorting algorithm to a fallback
+algorithm. The fallback is slower than the standard algorithm by
+perhaps a factor of three, but always behaves reasonably, no matter how
+bad the input.
+
+</P>
+<P>
+Lower values of <CODE>workFactor</CODE> reduce the amount of effort the
+standard algorithm will expend before resorting to the fallback. You
+should set this parameter carefully; too low, and many inputs will be
+handled by the fallback algorithm and so compress rather slowly, too
+high, and your average-to-worst case compression times can become very
+large. The default value of 30 gives reasonable behaviour over a wide
+range of circumstances.
+
+</P>
+<P>
+Allowable values range from 0 to 250 inclusive. 0 is a special case,
+equivalent to using the default value of 30.
+
+</P>
+<P>
+Note that the compressed output generated is the same regardless of
+whether or not the fallback algorithm is used.
+
+</P>
+<P>
+Be aware also that this parameter may disappear entirely in future
+versions of the library. In principle it should be possible to devise a
+good way to automatically choose which algorithm to use. Such a
+mechanism would render the parameter obsolete.

+transfer data between them.

+</P>
+<P>
+Before each call to <CODE>BZ2_bzCompress</CODE>, <CODE>next_in</CODE> should point at
+the data to be compressed, and <CODE>avail_in</CODE> should indicate how many

+<P>
+Similarly, <CODE>next_out</CODE> should point to a buffer in which the
+compressed data is to be placed, with <CODE>avail_out</CODE> indicating how

+<CODE>next_out</CODE>, <CODE>avail_out</CODE> and <CODE>total_out</CODE> to reflect the
+number of bytes output.
+
+</P>
+<P>
+You may provide and remove as little or as much data as you like on each
+call of <CODE>BZ2_bzCompress</CODE>. In the limit, it is acceptable to supply and
+remove data one byte at a time, although this would be terribly
+inefficient. You should always ensure that at least one byte of output
+space is available at each call.
+
+</P>
+<P>
+A second purpose of <CODE>BZ2_bzCompress</CODE> is to request a change of mode of the
+compressed stream.
+
+</P>
+<P>
+Conceptually, a compressed stream can be in one of four states: IDLE,
+RUNNING, FLUSHING and FINISHING. Before initialisation
+(<CODE>BZ2_bzCompressInit</CODE>) and after termination (<CODE>BZ2_bzCompressEnd</CODE>), a
+stream is regarded as IDLE.
+
+</P>
+<P>
+Upon initialisation (<CODE>BZ2_bzCompressInit</CODE>), the stream is placed in the
+RUNNING state. Subsequent calls to <CODE>BZ2_bzCompress</CODE> should pass
+<CODE>BZ_RUN</CODE> as the requested action; other actions are illegal and
+will result in <CODE>BZ_SEQUENCE_ERROR</CODE>.
+
+</P>
+<P>
+At some point, the calling program will have provided all the input data
+it wants to. It will then want to finish up -- in effect, asking the
+library to process any data it might have buffered internally. In this
+state, <CODE>BZ2_bzCompress</CODE> will no longer attempt to read data from
+<CODE>next_in</CODE>, but it will want to write data to <CODE>next_out</CODE>.
+Because the output buffer supplied by the user can be arbitrarily small,
+the finishing-up operation cannot necessarily be done with a single call
+of <CODE>BZ2_bzCompress</CODE>.
+
+</P>
+<P>
+Instead, the calling program passes <CODE>BZ_FINISH</CODE> as an action to
+<CODE>BZ2_bzCompress</CODE>. This changes the stream's state to FINISHING. Any
+remaining input (ie, <CODE>next_in[0 .. avail_in-1]</CODE>) is compressed and
+transferred to the output buffer. To do this, <CODE>BZ2_bzCompress</CODE> must be
+called repeatedly until all the output has been consumed. At that
+point, <CODE>BZ2_bzCompress</CODE> returns <CODE>BZ_STREAM_END</CODE>, and the stream's
+state is set back to IDLE. <CODE>BZ2_bzCompressEnd</CODE> should then be
+called.
+
+</P>
+<P>
+Just to make sure the calling program does not cheat, the library makes
+a note of <CODE>avail_in</CODE> at the time of the first call to
+<CODE>BZ2_bzCompress</CODE> which has <CODE>BZ_FINISH</CODE> as an action (ie, at the
+time the program has announced its intention to not supply any more
+input). By comparing this value with that of <CODE>avail_in</CODE> over
+subsequent calls to <CODE>BZ2_bzCompress</CODE>, the library can detect any
+attempts to slip in more data to compress. Any calls for which this is
+detected will return <CODE>BZ_SEQUENCE_ERROR</CODE>. This indicates a
+programming mistake which should be corrected.
+
+</P>
+<P>
+Instead of asking to finish, the calling program may ask
+<CODE>BZ2_bzCompress</CODE> to take all the remaining input, compress it and
+terminate the current (Burrows-Wheeler) compression block. This could
+be useful for error control purposes. The mechanism is analogous to
+that for finishing: call <CODE>BZ2_bzCompress</CODE> with an action of
+<CODE>BZ_FLUSH</CODE>, remove output data, and persist with the
+<CODE>BZ_FLUSH</CODE> action until the value <CODE>BZ_RUN</CODE> is returned. As
+with finishing, <CODE>BZ2_bzCompress</CODE> detects any attempt to provide more
+input data once the flush has begun.
+
+</P>
+<P>
+Once the flush is complete, the stream returns to the normal RUNNING
+state.
+
+</P>
+<P>
+This all sounds pretty complex, but isn't really. Here's a table
+which shows which actions are allowable in each state, what action
+will be taken, what the next state is, and what the non-error return
+values are. Note that you can't explicitly ask what state the
+stream is in, but nor do you need to -- it can be inferred from the

+<P>
+The high-level library facilitates use of
+<CODE>bzip2</CODE> data streams which form some part of a surrounding, larger
+data stream.
+
+<UL>
+<LI>For writing, the library takes an open file handle, writes
+
+compressed data to it, <CODE>fflush</CODE>es it but does not <CODE>fclose</CODE> it.
+The calling application can write its own data before and after the
+compressed data stream, using that same file handle.
+<LI>Reading is more complex, and the facilities are not as general
+
+as they could be since generality is hard to reconcile with efficiency.
+<CODE>BZ2_bzRead</CODE> reads from the compressed file in blocks of size
+<CODE>BZ_MAX_UNUSED</CODE> bytes, and in doing so probably will overshoot
+the logical end of compressed stream.
+To recover this data once decompression has
+ended, call <CODE>BZ2_bzReadGetUnused</CODE> after the last call of <CODE>BZ2_bzRead</CODE>
+(the one returning <CODE>BZ_STREAM_END</CODE>) but before calling
+<CODE>BZ2_bzReadClose</CODE>.
+</UL>
+
+<P>
+This mechanism makes it easy to decompress multiple <CODE>bzip2</CODE>
+streams placed end-to-end. As the end of one stream, when <CODE>BZ2_bzRead</CODE>
+returns <CODE>BZ_STREAM_END</CODE>, call <CODE>BZ2_bzReadGetUnused</CODE> to collect the
+unused data (copy it into your own buffer somewhere).
+That data forms the start of the next compressed stream.
+To start uncompressing that next stream, call <CODE>BZ2_bzReadOpen</CODE> again,
+feeding in the unused data via the <CODE>unused</CODE>/<CODE>nUnused</CODE>
+parameters.
+Keep doing this until <CODE>BZ_STREAM_END</CODE> return coincides with the
+physical end of file (<CODE>feof(f)</CODE>). In this situation
+<CODE>BZ2_bzReadGetUnused</CODE>
+will of course return no data.

+<P>
+<CODE>libbzip2</CODE> contains a number of internal assertion checks which
+should, needless to say, never be activated. Nevertheless, if an
+assertion should fail, behaviour depends on whether or not the library
+was compiled with <CODE>BZ_NO_STDIO</CODE> set.
+
+</P>
+<P>
+For a normal compile, an assertion failure yields the message
+
+<PRE>
+ bzip2/libbzip2: internal error number N.
+ This is a bug in bzip2/libbzip2, 1.0 of 21-Mar-2000.
+ Please report it to me at: jseward@acm.org. If this happened
+ when you were using some program which uses libbzip2 as a
+ component, you should also report this bug to the author(s)
+ of that program. Please make an effort to report this bug;
+ timely and accurate bug reports eventually lead to higher
+ quality software. Thanks. Julian Seward, 21 March 2000.
+</PRE>
+
+<P>
+where <CODE>N</CODE> is some error code number. <CODE>exit(3)</CODE>
+is then called.
+
+</P>
+<P>
+For a <CODE>stdio</CODE>-free library, assertion failures result
+in a call to a function declared as:
+
+<PRE>
+ extern void bz_internal_error ( int errcode );
+</PRE>
+
+<P>
+The relevant code is passed as a parameter. You should supply
+such a function.
+
+</P>
+<P>
+In either case, once an assertion failure has occurred, any
+<CODE>bz_stream</CODE> records involved can be regarded as invalid.
+You should not attempt to resume normal operation with them.
+
+</P>
+<P>
+You may, of course, change critical error handling to suit
+your needs. As I said above, critical errors indicate bugs
+in the library and should not occur. All "normal" error
+situations are indicated via error return codes from functions,
+and can be recovered from.

+<P><HR><P>
+
+
+<H1><A NAME="SEC43" HREF="manual_toc.html#TOC43">Miscellanea</A></H1>
+
+<P>
+These are just some random thoughts of mine. Your mileage may
+vary.
+
+</P>
+
+
+<H2><A NAME="SEC44" HREF="manual_toc.html#TOC44">Limitations of the compressed file format</A></H2>
+<P>
+<CODE>bzip2-1.0</CODE>, <CODE>0.9.5</CODE> and <CODE>0.9.0</CODE>
+use exactly the same file format as the previous
+version, <CODE>bzip2-0.1</CODE>. This decision was made in the interests of
+stability. Creating yet another incompatible compressed file format
+would create further confusion and disruption for users.
+
+</P>
+<P>
+Nevertheless, this is not a painless decision. Development
+work since the release of <CODE>bzip2-0.1</CODE> in August 1997
+has shown complexities in the file format which slow down
+decompression and, in retrospect, are unnecessary. These are:
+
+<UL>
+<LI>The run-length encoder, which is the first of the
+
+ compression transformations, is entirely irrelevant.
+ The original purpose was to protect the sorting algorithm
+ from the very worst case input: a string of repeated
+ symbols. But algorithm steps Q6a and Q6b in the original
+ Burrows-Wheeler technical report (SRC-124) show how
+ repeats can be handled without difficulty in block
+ sorting.
+<LI>The randomisation mechanism doesn't really need to be
+
+ there. Udi Manber and Gene Myers published a suffix
+ array construction algorithm a few years back, which
+ can be employed to sort any block, no matter how
+ repetitive, in O(N log N) time. Subsequent work by
+ Kunihiko Sadakane has produced a derivative O(N (log N)^2)
+ algorithm which usually outperforms the Manber-Myers
+ algorithm.
+
+ I could have changed to Sadakane's algorithm, but I find
+ it to be slower than <CODE>bzip2</CODE>'s existing algorithm for
+ most inputs, and the randomisation mechanism protects
+ adequately against bad cases. I didn't think it was
+ a good tradeoff to make. Partly this is due to the fact
+ that I was not flooded with email complaints about
+ <CODE>bzip2-0.1</CODE>'s performance on repetitive data, so
+ perhaps it isn't a problem for real inputs.
+
+ Probably the best long-term solution,
+ and the one I have incorporated into 0.9.5 and above,
+ is to use the existing sorting
+ algorithm initially, and fall back to a O(N (log N)^2)
+ algorithm if the standard algorithm gets into difficulties.
+<LI>The compressed file format was never designed to be
+
+ handled by a library, and I have had to jump though
+ some hoops to produce an efficient implementation of
+ decompression. It's a bit hairy. Try passing
+ <CODE>decompress.c</CODE> through the C preprocessor
+ and you'll see what I mean. Much of this complexity
+ could have been avoided if the compressed size of
+ each block of data was recorded in the data stream.
+<LI>An Adler-32 checksum, rather than a CRC32 checksum,
+
+ would be faster to compute.
+</UL>
+
+<P>
+It would be fair to say that the <CODE>bzip2</CODE> format was frozen
+before I properly and fully understood the performance
+consequences of doing so.
+
+</P>
+<P>
+Improvements which I was able to incorporate into
+0.9.0, despite using the same file format, are:
+
+<UL>
+<LI>Single array implementation of the inverse BWT. This
+
+ significantly speeds up decompression, presumably
+ because it reduces the number of cache misses.
+<LI>Faster inverse MTF transform for large MTF values. The
+
+ new implementation is based on the notion of sliding blocks
+ of values.
+<LI><CODE>bzip2-0.9.0</CODE> now reads and writes files with <CODE>fread</CODE>
+
+ and <CODE>fwrite</CODE>; version 0.1 used <CODE>putc</CODE> and <CODE>getc</CODE>.
+ Duh! Well, you live and learn.
+
+</UL>
+
+<P>
+Further ahead, it would be nice
+to be able to do random access into files. This will
+require some careful design of compressed file formats.
+
+</P>
+
+
+
+<H2><A NAME="SEC45" HREF="manual_toc.html#TOC45">Portability issues</A></H2>
+<P>
+After some consideration, I have decided not to use
+GNU <CODE>autoconf</CODE> to configure 0.9.5 or 1.0.
+
+</P>
+<P>
+<CODE>autoconf</CODE>, admirable and wonderful though it is,
+mainly assists with portability problems between Unix-like
+platforms. But <CODE>bzip2</CODE> doesn't have much in the way
+of portability problems on Unix; most of the difficulties appear
+when porting to the Mac, or to Microsoft's operating systems.
+<CODE>autoconf</CODE> doesn't help in those cases, and brings in a
+whole load of new complexity.
+
+</P>
+<P>
+Most people should be able to compile the library and program
+under Unix straight out-of-the-box, so to speak, especially
+if you have a version of GNU C available.
+
+</P>
+<P>
+There are a couple of <CODE>__inline__</CODE> directives in the code. GNU C
+(<CODE>gcc</CODE>) should be able to handle them. If you're not using
+GNU C, your C compiler shouldn't see them at all.
+If your compiler does, for some reason, see them and doesn't
+like them, just <CODE>#define</CODE> <CODE>__inline__</CODE> to be <CODE>/* */</CODE>. One
+easy way to do this is to compile with the flag <CODE>-D__inline__=</CODE>,
+which should be understood by most Unix compilers.
+
+</P>
+<P>
+If you still have difficulties, try compiling with the macro
+<CODE>BZ_STRICT_ANSI</CODE> defined. This should enable you to build the
+library in a strictly ANSI compliant environment. Building the program
+itself like this is dangerous and not supported, since you remove
+<CODE>bzip2</CODE>'s checks against compressing directories, symbolic links,
+devices, and other not-really-a-file entities. This could cause
+filesystem corruption!
+
+</P>
+<P>
+One other thing: if you create a <CODE>bzip2</CODE> binary for public
+distribution, please try and link it statically (<CODE>gcc -s</CODE>). This
+avoids all sorts of library-version issues that others may encounter
+later on.
+
+</P>
+<P>
+If you build <CODE>bzip2</CODE> on Win32, you must set <CODE>BZ_UNIX</CODE> to 0 and
+<CODE>BZ_LCCWIN32</CODE> to 1, in the file <CODE>bzip2.c</CODE>, before compiling.
+Otherwise the resulting binary won't work correctly.
+
+</P>
+
+
+
+<H2><A NAME="SEC46" HREF="manual_toc.html#TOC46">Reporting bugs</A></H2>
+<P>
+I tried pretty hard to make sure <CODE>bzip2</CODE> is
+bug free, both by design and by testing. Hopefully
+you'll never need to read this section for real.
+
+</P>
+<P>
+Nevertheless, if <CODE>bzip2</CODE> dies with a segmentation
+fault, a bus error or an internal assertion failure, it
+will ask you to email me a bug report. Experience with
+version 0.1 shows that almost all these problems can
+be traced to either compiler bugs or hardware problems.
+
+<UL>
+<LI>
+
+Recompile the program with no optimisation, and see if it
+works. And/or try a different compiler.
+I heard all sorts of stories about various flavours
+of GNU C (and other compilers) generating bad code for
+<CODE>bzip2</CODE>, and I've run across two such examples myself.
+
+2.7.X versions of GNU C are known to generate bad code from
+time to time, at high optimisation levels.
+If you get problems, try using the flags
+<CODE>-O2</CODE> <CODE>-fomit-frame-pointer</CODE> <CODE>-fno-strength-reduce</CODE>.
+You should specifically <EM>not</EM> use <CODE>-funroll-loops</CODE>.
+
+You may notice that the Makefile runs six tests as part of
+the build process. If the program passes all of these, it's
+a pretty good (but not 100%) indication that the compiler has
+done its job correctly.
+<LI>
+
+If <CODE>bzip2</CODE> crashes randomly, and the crashes are not
+repeatable, you may have a flaky memory subsystem. <CODE>bzip2</CODE>
+really hammers your memory hierarchy, and if it's a bit marginal,
+you may get these problems. Ditto if your disk or I/O subsystem
+is slowly failing. Yup, this really does happen.
+
+Try using a different machine of the same type, and see if
+you can repeat the problem.
+<LI>This isn't really a bug, but ... If <CODE>bzip2</CODE> tells
+
+you your file is corrupted on decompression, and you
+obtained the file via FTP, there is a possibility that you
+forgot to tell FTP to do a binary mode transfer. That absolutely
+will cause the file to be non-decompressible. You'll have to transfer
+it again.
+</UL>
+
+<P>
+If you've incorporated <CODE>libbzip2</CODE> into your own program
+and are getting problems, please, please, please, check that the
+parameters you are passing in calls to the library, are
+correct, and in accordance with what the documentation says
+is allowable. I have tried to make the library robust against
+such problems, but I'm sure I haven't succeeded.
+
+</P>
+<P>
+Finally, if the above comments don't help, you'll have to send
+me a bug report. Now, it's just amazing how many people will
+send me a bug report saying something like
+
+<PRE>
+ bzip2 crashed with segmentation fault on my machine
+</PRE>
+
+<P>
+and absolutely nothing else. Needless to say, a such a report
+is <EM>totally, utterly, completely and comprehensively 100% useless;
+a waste of your time, my time, and net bandwidth</EM>.
+With no details at all, there's no way I can possibly begin
+to figure out what the problem is.
+
+</P>
+<P>
+The rules of the game are: facts, facts, facts. Don't omit
+them because "oh, they won't be relevant". At the bare
+minimum:
+
+<PRE>
+ Machine type. Operating system version.
+ Exact version of <CODE>bzip2</CODE> (do <CODE>bzip2 -V</CODE>).
+ Exact version of the compiler used.
+ Flags passed to the compiler.
+</PRE>
+
+<P>
+However, the most important single thing that will help me is
+the file that you were trying to compress or decompress at the
+time the problem happened. Without that, my ability to do anything
+more than speculate about the cause, is limited.
+
+</P>
+<P>
+Please remember that I connect to the Internet with a modem, so
+you should contact me before mailing me huge files.
+
+</P>
+
+
+
+<H2><A NAME="SEC47" HREF="manual_toc.html#TOC47">Did you get the right package?</A></H2>
+
+<P>
+<CODE>bzip2</CODE> is a resource hog. It soaks up large amounts of CPU cycles
+and memory. Also, it gives very large latencies. In the worst case, you
+can feed many megabytes of uncompressed data into the library before
+getting any compressed output, so this probably rules out applications
+requiring interactive behaviour.
+
+</P>
+<P>
+These aren't faults of my implementation, I hope, but more
+an intrinsic property of the Burrows-Wheeler transform (unfortunately).
+Maybe this isn't what you want.
+
+</P>
+<P>
+If you want a compressor and/or library which is faster, uses less
+memory but gets pretty good compression, and has minimal latency,
+consider Jean-loup
+Gailly's and Mark Adler's work, <CODE>zlib-1.1.2</CODE> and
+<CODE>gzip-1.2.4</CODE>. Look for them at
+
+</P>
+<P>
+<CODE>http://www.cdrom.com/pub/infozip/zlib</CODE> and
+<CODE>http://www.gzip.org</CODE> respectively.
+
+</P>
+<P>
+For something faster and lighter still, you might try Markus F X J
+Oberhumer's <CODE>LZO</CODE> real-time compression/decompression library, at
+<BR> <CODE>http://wildsau.idv.uni-linz.ac.at/mfx/lzo.html</CODE>.
+
+</P>
+<P>
+If you want to use the <CODE>bzip2</CODE> algorithms to compress small blocks
+of data, 64k bytes or smaller, for example on an on-the-fly disk
+compressor, you'd be well advised not to use this library. Instead,
+I've made a special library tuned for that kind of use. It's part of
+<CODE>e2compr-0.40</CODE>, an on-the-fly disk compressor for the Linux
+<CODE>ext2</CODE> filesystem. Look at
+<CODE>http://www.netspace.net.au/~reiter/e2compr</CODE>.
+
+</P>
+
+
+
+<H2><A NAME="SEC48" HREF="manual_toc.html#TOC48">Testing</A></H2>
+
+<P>
+A record of the tests I've done.
+
+</P>
+<P>
+First, some data sets:
+
+<UL>
+<LI>B: a directory containing 6001 files, one for every length in the
+
+ range 0 to 6000 bytes. The files contain random lowercase
+ letters. 18.7 megabytes.
+<LI>H: my home directory tree. Documents, source code, mail files,
+
+ compressed data. H contains B, and also a directory of
+ files designed as boundary cases for the sorting; mostly very
+ repetitive, nasty files. 565 megabytes.
+<LI>A: directory tree holding various applications built from source:
+
+ <CODE>egcs</CODE>, <CODE>gcc-2.8.1</CODE>, KDE, GTK, Octave, etc.
+ 2200 megabytes.
+</UL>
+
+<P>
+The tests conducted are as follows. Each test means compressing
+(a copy of) each file in the data set, decompressing it and
+comparing it against the original.
+
+</P>
+<P>
+First, a bunch of tests with block sizes and internal buffer
+sizes set very small,
+to detect any problems with the

+If you are (justifiably) paranoid and want to see what 'make install'
