- Redesigned how cancellation unblocks a thread from internal
- cancellation points (sem_wait, pthread_join,
- pthread_cond_{wait,timedwait}).
- Cancellation won't eat a signal in any of these functions
- (*required* by POSIX and Single Unix Spec!).
- * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
- simultaneous condition variable signal (not required by POSIX
- or Single Unix Spec, but nice).
- * spinlock.c: __pthread_lock queues back any received restarts
- that don't belong to it instead of assuming ownership of lock
- upon any restart; fastlock can no longer be acquired by two threads
- simultaneously.
- * restart.h: Restarts queue even on kernels that don't have
- queued real time signals (2.0, early 2.1), thanks to atomic counter,

- thread's initial mask so easily. Take this opportunity to simplify
- the clone implementation by only accepting a single void* argument.
-
- * manager.c (__pthread_manager): Put thread vitals in the thread
- struct instead of as arguments through clone.
- (pthread_start_thread): Look for them there.
- * internals.h (struct _pthread): Add p_initial_fn,
- p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
- * pthread.c (pthread_initialize_manager): Revise clone invocation.

-Release 0.9:
-- more ports (SH, IA-64, s390)
-- many bug fixes
-- timed sync object wait functions
-- barrier implementation
-- spinlocks implementation
-- thread register on x86
-- variable stack size and position on some platforms
-
-Release 0.8:
-(ehmm, forgot to update, don't know anymore)
-
-Release 0.7:
-- Destructors for thread-specific data now conform to the POSIX semantics
- (call destructors again if non-NULL TSD remains after a round of
- destruction).
-- Implemented thread-specific data as a sparse array, allows more TSD keys
- and smaller thread descriptors (Ulrich Drepper).
-- Added "error checking" mutexes.
-- Protect against multiple sigwait() on the same signals.
-- Simplified implementation of semaphores when compare_and_swap is
- not available.
-- Fixed bug in fork() where stdin was closed if fork() was called before
- the first pthread_create().
-- Fixed bug in the gethostby*_r functions (bad result if null bytes
- in addresses).
-- Typos in manual pages corrected.
-- First cut at a PowerPC port (not working yet, runs into problems
- with gcc and with the C library).
-
-Release 0.6:
-- Validation of thread identifiers: no more crashes when operating on
- a thread that has exited (based on Pavel Krauz's ideas).
-- Added fallback implementation of semaphores for the 386 and the
- Sparc.
-- Fixed a bug in signal handling causing false restarts of suspended
- threads.
-- Fixed a bug in realtime scheduling causing all threads to have
- default scheduling on Ix86 with libc5.
-- With realtime scheduling, unlocking a mutex now restarts the
- highest priority thread waiting on the mutex, not the
- first-suspended thread (Richard Neitzel).
-- Timing a process now returns cumulative times for all threads, not
- just times for the initial thread (suggested by Wolfram Gloger).
-- Cleaned up name space (internal defs prefixed by __, weak aliases
- for non-portable extensions).
-- MIPS port (contributed by Ralf Baechle).
-
-Release 0.5:
-- Signal-safe semaphores a la POSIX 1003.1b added.
-- Locking bug in pthread_mutex_trylock over recursive mutexes fixed.
-- Race conditions in thread cancellation fixed.
-- Sparc port (contributed by Miguel de Icaza).
-- Support for getpwnam_r and getpwuid_r.
-- Added pthread_kill_other_threads_np to be used in conjunction with
- exec*().
-
-Release 0.4:
-- Manual pages for all functions.
-- Synchronization bug causing accumulation of zombie processes fixed.
-- Race condition in pthread_cond_timedwait fixed.
-- Recursive mutexes are back by popular demand.
-- Partial support for realtime scheduling (initiated by Richard Neitzel).
-- pthread.h cleaned up a lot: now C++ compatible, added missing "const"
- qualifiers, added short documentation, put to GNU libc standards
- for name space pollution (Ulrich Drepper).
-- Motorola 68k port (contributed by Andreas Schwab).
-- Interaction with fork(2) cleaned up a lot.
-
-Release 0.3:
-- Thread creation and reclaimation now performed by a centralized
- "thread manager" thread.
-- Removed recursive mutexes to make regular mutexes more efficient.
-- Now available as a shared library (contributed by Richard Henderson).
-- Alpha port (contributed by Richard Henderson).
-- Fixed many small discrepancies with Posix 1003.1c.
-- Put under the LGPL instead of the GPL.
-
-Release 0.2:
-- Reentrant libc functions (adapted from libc 5.3.9 by Peeter Joot)
-- pthread_cond_wait did not reacquire the mutex correctly on return
-- More efficient pthread_cond_broadcast
-
-Release 0.1:
-- First public release

-<H2><A NAME="A">A. The big picture</A></H2>
-
-<H4><A NAME="A.1">A.1: What is LinuxThreads?</A></H4>
-
-LinuxThreads is a Linux library for multi-threaded programming.
-It implements the Posix 1003.1c API (Application Programming
-Interface) for threads. It runs on any Linux system with kernel 2.0.0
-or more recent, and a suitable C library (see section <A HREF="C">C</A>).
-<P>
-
-<H4><A NAME="A.2">A.2: What are threads?</A></H4>
-
-A thread is a sequential flow of control through a program.
-Multi-threaded programming is, thus, a form of parallel programming
-where several threads of control are executing concurrently in the
-program. All threads execute in the same memory space, and can
-therefore work concurrently on shared data.<P>
-
-Multi-threaded programming differs from Unix-style multi-processing in
-that all threads share the same memory space (and a few other system
-resources, such as file descriptors), instead of running in their own
-memory space as is the case with Unix processes.<P>
-
-Threads are useful for two reasons. First, they allow a program to
-exploit multi-processor machines: the threads can run in parallel on
-several processors, allowing a single program to divide its work
-between several processors, thus running faster than a single-threaded
-program, which runs on only one processor at a time. Second, some
-programs are best expressed as several threads of control that
-communicate together, rather than as one big monolithic sequential
-program. Examples include server programs, overlapping asynchronous
-I/O, and graphical user interfaces.<P>
-
-<H4><A NAME="A.3">A.3: What is POSIX 1003.1c?</A></H4>
-
-It's an API for multi-threaded programming standardized by IEEE as
-part of the POSIX standards. Most Unix vendors have endorsed the
-POSIX 1003.1c standard. Implementations of the 1003.1c API are
-already available under Sun Solaris 2.5, Digital Unix 4.0,
-Silicon Graphics IRIX 6, and should soon be available from other
-vendors such as IBM and HP. More generally, the 1003.1c API is
-replacing relatively quickly the proprietary threads library that were
-developed previously under Unix, such as Mach cthreads, Solaris
-threads, and IRIX sprocs. Thus, multithreaded programs using the
-1003.1c API are likely to run unchanged on a wide variety of Unix
-platforms.<P>
-
-<H4><A NAME="A.4">A.4: What is the status of LinuxThreads?</A></H4>
-
-LinuxThreads implements almost all of Posix 1003.1c, as well as a few
-extensions. The only part of LinuxThreads that does not conform yet
-to Posix is signal handling (see section <A HREF="#J">J</A>). Apart
-from the signal stuff, all the Posix 1003.1c base functionality,
-as well as a number of optional extensions, are provided and conform
-to the standard (to the best of my knowledge).
-The signal stuff is hard to get right, at least without special kernel
-support, and while I'm definitely looking at ways to implement the
-Posix behavior for signals, this might take a long time before it's
-completed.<P>
-
-<H4><A NAME="A.5">A.5: How stable is LinuxThreads?</A></H4>
-
-The basic functionality (thread creation and termination, mutexes,
-conditions, semaphores) is very stable. Several industrial-strength
-programs, such as the AOL multithreaded Web server, use LinuxThreads
-and seem quite happy about it. There used to be some rough edges in
-the LinuxThreads / C library interface with libc 5, but glibc 2
-fixes all of those problems and is now the standard C library on major
-Linux distributions (see section <A HREF="#C">C</A>). <P>
-
-<HR>

-<H2><A NAME="B">B. Getting more information</A></H2>
-
-<H4><A NAME="B.1">B.1: What are good books and other sources of
-information on POSIX threads?</A></H4>
-
-The FAQ for comp.programming.threads lists several books:
-<A HREF="http://www.serpentine.com/~bos/threads-faq/">http://www.serpentine.com/~bos/threads-faq/</A>.<P>
-
-There are also some online tutorials. Follow the links from the
-LinuxThreads web page:
-<A HREF="http://pauillac.inria.fr/~xleroy/linuxthreads">http://pauillac.inria.fr/~xleroy/linuxthreads</A>.<P>
-
-<H4><A NAME="B.2">B.2: I'd like to be informed of future developments on
-LinuxThreads. Is there a mailing list for this purpose?</A></H4>
-
-I post LinuxThreads-related announcements on the newsgroup
-<A HREF="news:comp.os.linux.announce">comp.os.linux.announce</A>,
-and also on the mailing list
-<code>linux-threads@magenet.com</code>.
-You can subscribe to the latter by writing
-<A HREF="mailto:majordomo@magenet.com">majordomo@magenet.com</A>.<P>
-
-<H4><A NAME="B.3">B.3: What are good places for discussing
-LinuxThreads?</A></H4>
-
-For questions about programming with POSIX threads in general, use
-the newsgroup
-<A HREF="news:comp.programming.threads">comp.programming.threads</A>.
-Be sure you read the
-<A HREF="http://www.serpentine.com/~bos/threads-faq/">FAQ</A>
-for this group before you post.<P>
-
-For Linux-specific questions, use
-<A
-HREF="news:comp.os.linux.development.apps">comp.os.linux.development.apps</A>
-and <A
-HREF="news:comp.os.linux.development.kernel">comp.os.linux.development.kernel</A>.
-The latter is especially appropriate for questions relative to the
-interface between the kernel and LinuxThreads.<P>
-
-<H4><A NAME="B.4">B.4: How should I report a possible bug in
-LinuxThreads?</A></H4>
-
-If you're using glibc 2, the best way by far is to use the
-<code>glibcbug</code> script to mail a bug report to the glibc
-maintainers. <P>
-
-If you're using an older libc, or don't have the <code>glibcbug</code>
-script on your machine, then e-mail me directly
-(<code>Xavier.Leroy@inria.fr</code>). <P>
-
-In both cases, before sending the bug report, make sure that it is not
-addressed already in this FAQ. Also, try to send a short program that
-reproduces the weird behavior you observed. <P>
-
-<H4><A NAME="B.5">B.5: I'd like to read the POSIX 1003.1c standard. Is
-it available online?</A></H4>
-
-Unfortunately, no. POSIX standards are copyrighted by IEEE, and
-IEEE does not distribute them freely. You can buy paper copies from
-IEEE, but the price is fairly high ($120 or so). If you disagree with
-this policy and you're an IEEE member, be sure to let them know.<P>
-
-On the other hand, you probably don't want to read the standard. It's
-very hard to read, written in standard-ese, and targeted to
-implementors who already know threads inside-out. A good book on
-POSIX threads provides the same information in a much more readable form.
-I can personally recommend Dave Butenhof's book, <CITE>Programming
-with POSIX threads</CITE> (Addison-Wesley). Butenhof was part of the
-POSIX committee and also designed the Digital Unix implementations of
-POSIX threads, and it shows.<P>
-
-Another good source of information is the X/Open Group Single Unix
-specification which is available both
-<A HREF="http://www.rdg.opengroup.org/onlinepubs/7908799/index.html">on-line</A>
-and as a
-<A HREF="http://www.UNIX-systems.org/gosolo2/">book and CD/ROM</A>.
-That specification includes pretty much all the POSIX standards,
-including 1003.1c, with some extensions and clarifications.<P>
-
-<HR>
-<P>
-
-<H2><A NAME="C">C. Issues related to the C library</A></H2>
-
-<H4><A NAME="C.1">C.1: Which version of the C library should I use
-with LinuxThreads?</A></H4>
-
-The best choice by far is glibc 2, a.k.a. libc 6. It offers very good
-support for multi-threading, and LinuxThreads has been closely
-integrated with glibc 2. The glibc 2 distribution contains the
-sources of a specially adapted version of LinuxThreads.<P>
-
-glibc 2 comes preinstalled as the default C library on several Linux
-distributions, such as RedHat 5 and up, and Debian 2.
-Those distributions include the version of LinuxThreads matching
-glibc 2.<P>
-
-<H4><A NAME="C.2">C.2: My system has libc 5 preinstalled, not glibc
-2. Can I still use LinuxThreads?</H4>
-
-Yes, but you're likely to run into some problems, as libc 5 only
-offers minimal support for threads and contains some bugs that affect
-multithreaded programs. <P>
-
-The versions of libc 5 that work best with LinuxThreads are
-libc 5.2.18 on the one hand, and libc 5.4.12 or later on the other hand.
-Avoid 5.3.12 and 5.4.7: these have problems with the per-thread errno
-variable. <P>
-
-<H4><A NAME="C.3">C.3: So, should I switch to glibc 2, or stay with a
-recent libc 5?</A></H4>
-
-I'd recommend you switch to glibc 2. Even for single-threaded
-programs, glibc 2 is more solid and more standard-conformant than libc
-5. And the shortcomings of libc 5 almost preclude any serious
-multi-threaded programming.<P>
-
-Switching an already installed
-system from libc 5 to glibc 2 is not completely straightforward.
-See the <A HREF="http://sunsite.unc.edu/LDP/HOWTO/Glibc2-HOWTO.html">Glibc2
-HOWTO</A> for more information. Much easier is (re-)installing a
-Linux distribution based on glibc 2, such as RedHat 6.<P>
-
-<H4><A NAME="C.4">C.4: Where can I find glibc 2 and the version of
-LinuxThreads that goes with it?</A></H4>
-
-On <code>prep.ai.mit.edu</code> and its many, many mirrors around the world.
-See <A
-HREF="http://www.gnu.org/order/ftp.html">http://www.gnu.org/order/ftp.html</A>
-for a list of mirrors.<P>
-
-<H4><A NAME="C.5">C.5: Where can I find libc 5 and the version of
-LinuxThreads that goes with it?</A></H4>
-
-For libc 5, see <A HREF="ftp://sunsite.unc.edu/pub/Linux/devel/GCC/"><code>ftp://sunsite.unc.edu/pub/Linux/devel/GCC/</code></A>.<P>
-
-For the libc 5 version of LinuxThreads, see
-<A HREF="ftp://ftp.inria.fr/INRIA/Projects/cristal/Xavier.Leroy/linuxthreads/">ftp://ftp.inria.fr/INRIA/Projects/cristal/Xavier.Leroy/linuxthreads/</A>.<P>
-
-<H4><A NAME="C.6">C.6: How can I recompile the glibc 2 version of the
-LinuxThreads sources?</A></H4>
-
-You must transfer the whole glibc sources, then drop the LinuxThreads
-sources in the <code>linuxthreads/</code> subdirectory, then recompile
-glibc as a whole. There are now too many inter-dependencies between
-LinuxThreads and glibc 2 to allow separate re-compilation of LinuxThreads.
-<P>
-
-<H4><A NAME="C.7">C.7: What is the correspondence between LinuxThreads
-version numbers, libc version numbers, and RedHat version
-numbers?</A></H4>

-
-<H4><A NAME="D.1">D.1: When I compile LinuxThreads, I run into problems in
-file <code>libc_r/dirent.c</code></A></H4>
-
-You probably mean:
-<PRE>
- libc_r/dirent.c:94: structure has no member named `dd_lock'
-</PRE>
-I haven't actually seen this problem, but several users reported it.
-My understanding is that something is wrong in the include files of
-your Linux installation (<code>/usr/include/*</code>). Make sure
-you're using a supported version of the libc 5 library. (See question <A
-HREF="#C.2">C.2</A>).<P>
-
-<H4><A NAME="D.2">D.2: When I compile LinuxThreads, I run into problems with
-<CODE>/usr/include/sched.h</CODE>: there are several occurrences of
-<CODE>_p</CODE> that the C compiler does not understand</A></H4>
-
-Yes, <CODE>/usr/include/sched.h</CODE> that comes with libc 5.3.12 is broken.
-Replace it with the <code>sched.h</code> file contained in the
-LinuxThreads distribution. But really you should not be using libc
-5.3.12 with LinuxThreads! (See question <A HREF="#C.2">C.1</A>.)<P>
-
-<H4><A NAME="D.3">D.3: My program does <CODE>fdopen()</CODE> on a file
-descriptor opened on a pipe. When I link it with LinuxThreads,
-<CODE>fdopen()</CODE> always returns NULL!</A></H4>
-
-You're using one of the buggy versions of libc (5.3.12, 5.4.7., etc).
-See question <A HREF="#C.1">C.1</A> above.<P>
-
-<H4><A NAME="D.4">D.4: My program creates a lot of threads, and after
-a while <CODE>pthread_create()</CODE> no longer returns!</A></H4>
-
-This is known bug in the version of LinuxThreads that comes with glibc
-2.1.1. An upgrade to 2.1.2 is recommended. <P>
-
-<H4><A NAME="D.5">D.5: When I'm running a program that creates N
-threads, <code>top</code> or <code>ps</code>
-display N+2 processes that are running my program. What do all these
-processes correspond to?</A></H4>
-
-Due to the general "one process per thread" model, there's one process
-for the initial thread and N processes for the threads it created
-using <CODE>pthread_create</CODE>. That leaves one process
-unaccounted for. That extra process corresponds to the "thread
-manager" thread, a thread created internally by LinuxThreads to handle
-thread creation and thread termination. This extra thread is asleep
-most of the time.
-
-<H4><A NAME="D.6">D.6: Scheduling seems to be very unfair when there
-is strong contention on a mutex: instead of giving the mutex to each
-thread in turn, it seems that it's almost always the same thread that
-gets the mutex. Isn't this completely broken behavior?</A></H4>
-
-That behavior has mostly disappeared in recent releases of
-LinuxThreads (version 0.8 and up). It was fairly common in older
-releases, though.
-
-What happens in LinuxThreads 0.7 and before is the following: when a
-thread unlocks a mutex, all other threads that were waiting on the
-mutex are sent a signal which makes them runnable. However, the
-kernel scheduler may or may not restart them immediately. If the
-thread that unlocked the mutex tries to lock it again immediately
-afterwards, it is likely that it will succeed, because the threads
-haven't yet restarted. This results in an apparently very unfair
-behavior, when the same thread repeatedly locks and unlocks the mutex,
-while other threads can't lock the mutex.<P>
-
-In LinuxThreads 0.8 and up, <code>pthread_unlock</code> restarts only
-one waiting thread, and pre-assign the mutex to that thread. Hence,
-if the thread that unlocked the mutex tries to lock it again
-immediately, it will block until other waiting threads have had a
-chance to lock and unlock the mutex. This results in much fairer
-scheduling.<P>
-
-Notice however that even the old "unfair" behavior is perfectly
-acceptable with respect to the POSIX standard: for the default
-scheduling policy, POSIX makes no guarantees of fairness, such as "the

-
-No. You're going to run into several hard limits:
-<UL>
-<LI>Each thread, from the kernel's standpoint, is one process. Stock
-Linux kernels are limited to at most 512 processes for the super-user,
-and half this number for regular users. This can be changed by
-changing <code>NR_TASKS</code> in <code>include/linux/tasks.h</code>
-and recompiling the kernel. On the x86 processors at least,
-architectural constraints seem to limit <code>NR_TASKS</code> to 4090
-at most.
-<LI>LinuxThreads contains a table of all active threads. This table
-has room for 1024 threads at most. To increase this limit, you must
-change <code>PTHREAD_THREADS_MAX</code> in the LinuxThreads sources
-and recompile.
-<LI>By default, each thread reserves 2M of virtual memory space for
-its stack. This space is just reserved; actual memory is allocated
-for the stack on demand. But still, on a 32-bit processor, the total
-virtual memory space available for the stacks is on the order of 1G,
-meaning that more than 500 threads will have a hard time fitting in.
-You can overcome this limitation by moving to a 64-bit platform, or by
-allocating smaller stacks yourself using the <code>setstackaddr</code>
-attribute.
-<LI>Finally, the Linux kernel contains many algorithms that run in
-time proportional to the number of process table entries. Increasing
-this number drastically will slow down the kernel operations
-noticeably.
-</UL>
-(Other POSIX threads libraries have similar limitations, by the way.)
-For all those reasons, you'd better restructure your application so
-that it doesn't need more than, say, 100 threads. For instance,

-
-The POSIX standard provides <B>no</B> mechanism by which a thread A can

-Notice that <CODE>thr_suspend()</CODE> is inherently dangerous and

-It affects include files in three ways:

-e.g. <CODE>gethostbyname_r()</CODE> as a reentrant equivalent to
-<CODE>gethostbyname()</CODE>.<P>
-
-<LI> If <CODE>_REENTRANT</CODE> is defined, some

-program, stdio functions require additional locking, which the macros
-don't perform, so we must call functions instead.<P>
-
-<LI> More importantly, <code>&lt;errno.h&gt;</code> redefines errno when
-<CODE>_REENTRANT</CODE> is
-defined, so that errno refers to the thread-specific errno location
-rather than the global errno variable. This is achieved by the
-following <code>#define</code> in <code>&lt;errno.h&gt;</code>:
-<PRE>
- #define errno (*(__errno_location()))
-</PRE>
-which causes each reference to errno to call the
-<CODE>__errno_location()</CODE> function for obtaining the location
-where error codes are stored. libc provides a default definition of
-<CODE>__errno_location()</CODE> that always returns
-<code>&errno</code> (the address of the global errno variable). Thus,
-for programs not linked with LinuxThreads, defining

-But LinuxThreads redefines <CODE>__errno_location()</CODE> to return a

-a different errno location.

-<H4><A NAME="H.3">H.3: What happens if I link LinuxThreads with code

-
-Lots of trouble. If the code uses <CODE>getc()</CODE> or

-of the stdio buffers; this can cause lost output, duplicate output, or
-just crash other stdio functions. If the code consults errno, it will

-Assume this code is not compiled with <CODE>-D_REENTRANT</CODE>, and

-in the location pointed to by <CODE>__errno_location()</CODE>, which
-is the thread-local errno variable. Then, the code above sees that
-<CODE>read()</CODE> returns -1 and looks up errno. Since

-The short answer is: because the Linux kernel you're using does not
-support realtime signals. <P>
-
-LinuxThreads needs two signals for its internal operation.
-One is used to suspend and restart threads blocked on mutex, condition
-or semaphore operations. The other is used for thread

-
-On ``old'' kernels (2.0 and early 2.1 kernels), there are only 32

-
-On recent kernels (2.2 and up), more than 32 signals are provided in

-
-Another, less involving solution is to call X functions only from the

-
-On the other hand, signal masks are per-thread: each thread chooses

-process down, use <code>pthread_cancel()</code>.<P>
-
-<H4><A NAME="J.3">J.3: I've installed a handler on a signal. Which
-thread executes the handler when the signal is received?</A></H4>
-
-If the signal is generated by a thread during its execution (e.g. a
-thread executes a division by zero and thus generates a
-<CODE>SIGFPE</CODE> signal), then the handler is executed by that
-thread. This also applies to signals generated by
-<CODE>raise()</CODE>.<P>
-
-If the signal is sent to a particular thread using
-<CODE>pthread_kill()</CODE>, then that thread executes the handler.<P>
-
-If the signal is sent via <CODE>kill()</CODE> or the tty interface
-(e.g. by pressing ctrl-C), then the POSIX specs say that the handler
-is executed by any thread in the process that does not currently block
-the signal. In other terms, POSIX considers that the signal is sent
-to the process (the collection of all threads) as a whole, and any
-thread that is not blocking this signal can then handle it.<P>
-
-The latter case is where LinuxThreads departs from the POSIX specs.
-In LinuxThreads, there is no real notion of ``the process as a whole'':
-in the kernel, each thread is really a distinct process with a
-distinct PID, and signals sent to the PID of a thread can only be
-handled by that thread. As long as no thread is blocking the signal,
-the behavior conforms to the standard: one (unspecified) thread of the
-program handles the signal. But if the thread to which PID the signal
-is sent blocks the signal, and some other thread does not block the
-signal, then LinuxThreads will simply queue in
-that thread and execute the handler only when that thread unblocks
-the signal, instead of executing the handler immediately in the other
-thread that does not block the signal.<P>
-
-This is to be viewed as a LinuxThreads bug, but I currently don't see
-any way to implement the POSIX behavior without kernel support.<P>
-
-<H4><A NAME="J.3">J.3: How shall I go about mixing signals and threads
-in my program? </A></H4>
-
-The less you mix them, the better. Notice that all
-<CODE>pthread_*</CODE> functions are not async-signal safe, meaning
-that you should not call them from signal handlers. This
-recommendation is not to be taken lightly: your program can deadlock
-if you call a <CODE>pthread_*</CODE> function from a signal handler!
-<P>
-
-The only sensible things you can do from a signal handler is set a
-global flag, or call <CODE>sem_post</CODE> on a semaphore, to record
-the delivery of the signal. The remainder of the program can then
-either poll the global flag, or use <CODE>sem_wait()</CODE> and
-<CODE>sem_trywait()</CODE> on the semaphore.<P>
-
-Another option is to do nothing in the signal handler, and dedicate
-one thread (preferably the initial thread) to wait synchronously for
-signals, using <CODE>sigwait()</CODE>, and send messages to the other
-threads accordingly.
-
-<H4><A NAME="J.4">J.4: When one thread is blocked in
-<CODE>sigwait()</CODE>, other threads no longer receive the signals
-<CODE>sigwait()</CODE> is waiting for! What happens? </A></H4>
-
-It's an unfortunate consequence of how LinuxThreads implements
-<CODE>sigwait()</CODE>. Basically, it installs signal handlers on all
-signals waited for, in order to record which signal was received.
-Since signal handlers are shared with the other threads, this
-temporarily deactivates any signal handlers you might have previously
-installed on these signals.<P>
-
-Though surprising, this behavior actually seems to conform to the
-POSIX standard. According to POSIX, <CODE>sigwait()</CODE> is
-guaranteed to work as expected only if all other threads in the
-program block the signals waited for (otherwise, the signals could be
-delivered to other threads than the one doing <CODE>sigwait()</CODE>,
-which would make <CODE>sigwait()</CODE> useless). In this particular
-case, the problem described in this question does not appear.<P>
-
-One day, <CODE>sigwait()</CODE> will be implemented in the kernel,
-along with others POSIX 1003.1b extensions, and <CODE>sigwait()</CODE>
-will have a more natural behavior (as well as better performances).<P>

-<H2><A NAME="K">K. Internals of LinuxThreads</A></H2>
-
-<H4><A NAME="K.1">K.1: What is the implementation model for
-LinuxThreads?</A></H4>
-
-LinuxThreads follows the so-called "one-to-one" model: each thread is
-actually a separate process in the kernel. The kernel scheduler takes
-care of scheduling the threads, just like it schedules regular
-processes. The threads are created with the Linux
-<code>clone()</code> system call, which is a generalization of
-<code>fork()</code> allowing the new process to share the memory
-space, file descriptors, and signal handlers of the parent.<P>
-
-Advantages of the "one-to-one" model include:
-<UL>
-<LI> minimal overhead on CPU-intensive multiprocessing (with
-about one thread per processor);
-<LI> minimal overhead on I/O operations;
-<LI> a simple and robust implementation (the kernel scheduler does
-most of the hard work for us).
-</UL>
-The main disadvantage is more expensive context switches on mutex and
-condition operations, which must go through the kernel. This is
-mitigated by the fact that context switches in the Linux kernel are
-pretty efficient.<P>
-
-<H4><A NAME="K.2">K.2: Have you considered other implementation
-models?</A></H4>
-
-There are basically two other models. The "many-to-one" model
-relies on a user-level scheduler that context-switches between the
-threads entirely in user code; viewed from the kernel, there is only
-one process running. This model is completely out of the question for
-me, since it does not take advantage of multiprocessors, and require
-unholy magic to handle blocking I/O operations properly. There are
-several user-level thread libraries available for Linux, but I found
-all of them deficient in functionality, performance, and/or robustness.
-<P>
-
-The "many-to-many" model combines both kernel-level and user-level
-scheduling: several kernel-level threads run concurrently, each
-executing a user-level scheduler that selects between user threads.
-Most commercial Unix systems (Solaris, Digital Unix, IRIX) implement
-POSIX threads this way. This model combines the advantages of both
-the "many-to-one" and the "one-to-one" model, and is attractive
-because it avoids the worst-case behaviors of both models --
-especially on kernels where context switches are expensive, such as
-Digital Unix. Unfortunately, it is pretty complex to implement, and
-requires kernel support which Linux does not provide. Linus Torvalds
-and other Linux kernel developers have always been pushing the
-"one-to-one" model in the name of overall simplicity, and are doing a
-pretty good job of making kernel-level context switches between
-threads efficient. LinuxThreads is just following the general
-direction they set.<P>

-GNU LIBRARY GENERAL PUBLIC LICENSE
-**********************************
-
- Version 2, June 1991
-
- Copyright (C) 1991 Free Software Foundation, Inc.
- 59 Temple Place -- Suite 330, Boston, MA 02111-1307, USA
-
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- [This is the first released version of the library GPL. It is
- numbered 2 because it goes with version 2 of the ordinary GPL.]
-
-Preamble
-========
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Library General Public License, applies to some
-specially designated Free Software Foundation software, and to any
-other libraries whose authors decide to use it. You can use it for
-your libraries, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it in
-new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the library, or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- Our method of protecting your rights has two steps: (1) copyright
-the library, and (2) offer you this license which gives you legal
-permission to copy, distribute and/or modify the library.
-
- Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library. If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original
-version, so that any problems introduced by others will not reflect on
-the original authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software. To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License, which was designed for utility
-programs. This license, the GNU Library General Public License,
-applies to certain designated libraries. This license is quite
-different from the ordinary one; be sure to read it in full, and don't
-assume that anything in it is the same as in the ordinary license.
-
- The reason we have a separate public license for some libraries is
-that they blur the distinction we usually make between modifying or
-adding to a program and simply using it. Linking a program with a
-library, without changing the library, is in some sense simply using
-the library, and is analogous to running a utility program or
-application program. However, in a textual and legal sense, the linked
-executable is a combined work, a derivative of the original library,
-and the ordinary General Public License treats it as such.
-
- Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries. We
-concluded that weaker conditions might promote sharing better.
-
- However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves. This Library General Public License is intended
-to permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them. (We have not seen how to
-achieve this as regards changes in header files, but we have achieved
-it as regards changes in the actual functions of the Library.) The
-hope is that this will lead to faster development of free libraries.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, while the latter only
-works together with the library.
-
- Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.
-
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library which
- contains a notice placed by the copyright holder or other
- authorized party saying it may be distributed under the terms of
- this Library General Public License (also called "this License").
- Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
- prepared so as to be conveniently linked with application programs
- (which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
- which has been distributed under these terms. A "work based on the
- Library" means either the Library or any derivative work under
- copyright law: that is to say, a work containing the Library or a
- portion of it, either verbatim or with modifications and/or
- translated straightforwardly into another language. (Hereinafter,
- translation is included without limitation in the term
- "modification".)
-
- "Source code" for a work means the preferred form of the work for
- making modifications to it. For a library, complete source code
- means all the source code for all modules it contains, plus any
- associated interface definition files, plus the scripts used to
- control compilation and installation of the library.
-
- Activities other than copying, distribution and modification are
- not covered by this License; they are outside its scope. The act
- of running a program using the Library is not restricted, and
- output from such a program is covered only if its contents
- constitute a work based on the Library (independent of the use of
- the Library in a tool for writing it). Whether that is true
- depends on what the Library does and what the program that uses
- the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
- complete source code as you receive it, in any medium, provided
- that you conspicuously and appropriately publish on each copy an
- appropriate copyright notice and disclaimer of warranty; keep
- intact all the notices that refer to this License and to the
- absence of any warranty; and distribute a copy of this License
- along with the Library.
-
- You may charge a fee for the physical act of transferring a copy,
- and you may at your option offer warranty protection in exchange
- for a fee.
-
- 2. You may modify your copy or copies of the Library or any portion
- of it, thus forming a work based on the Library, and copy and
- distribute such modifications or work under the terms of Section 1
- above, provided that you also meet all of these conditions:
-
- a. The modified work must itself be a software library.
-
- b. You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c. You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d. If a facility in the modified Library refers to a function or
- a table of data to be supplied by an application program that
- uses the facility, other than as an argument passed when the
- facility is invoked, then you must make a good faith effort
- to ensure that, in the event an application does not supply
- such function or table, the facility still operates, and
- performs whatever part of its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots
- has a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function
- must be optional: if the application does not supply it, the
- square root function must still compute square roots.)
-
- These requirements apply to the modified work as a whole. If
- identifiable sections of that work are not derived from the
- Library, and can be reasonably considered independent and separate
- works in themselves, then this License, and its terms, do not
- apply to those sections when you distribute them as separate
- works. But when you distribute the same sections as part of a
- whole which is a work based on the Library, the distribution of
- the whole must be on the terms of this License, whose permissions
- for other licensees extend to the entire whole, and thus to each
- and every part regardless of who wrote it.
-
- Thus, it is not the intent of this section to claim rights or
- contest your rights to work written entirely by you; rather, the
- intent is to exercise the right to control the distribution of
- derivative or collective works based on the Library.
-
- In addition, mere aggregation of another work not based on the
- Library with the Library (or with a work based on the Library) on
- a volume of a storage or distribution medium does not bring the
- other work under the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
- License instead of this License to a given copy of the Library.
- To do this, you must alter all the notices that refer to this
- License, so that they refer to the ordinary GNU General Public
- License, version 2, instead of to this License. (If a newer
- version than version 2 of the ordinary GNU General Public License
- has appeared, then you can specify that version instead if you
- wish.) Do not make any other change in these notices.
-
- Once this change is made in a given copy, it is irreversible for
- that copy, so the ordinary GNU General Public License applies to
- all subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
- the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
- derivative of it, under Section 2) in object code or executable
- form under the terms of Sections 1 and 2 above provided that you
- accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software
- interchange.
-
- If distribution of object code is made by offering access to copy
- from a designated place, then offering equivalent access to copy
- the source code from the same place satisfies the requirement to
- distribute the source code, even though third parties are not
- compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
- Library, but is designed to work with the Library by being
- compiled or linked with it, is called a "work that uses the
- Library". Such a work, in isolation, is not a derivative work of
- the Library, and therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
- creates an executable that is a derivative of the Library (because
- it contains portions of the Library), rather than a "work that
- uses the library". The executable is therefore covered by this
- License. Section 6 states terms for distribution of such
- executables.
-
- When a "work that uses the Library" uses material from a header
- file that is part of the Library, the object code for the work may
- be a derivative work of the Library even though the source code is
- not. Whether this is true is especially significant if the work
- can be linked without the Library, or if the work is itself a
- library. The threshold for this to be true is not precisely
- defined by law.
-
- If such an object file uses only numerical parameters, data
- structure layouts and accessors, and small macros and small inline
- functions (ten lines or less in length), then the use of the object
- file is unrestricted, regardless of whether it is legally a
- derivative work. (Executables containing this object code plus
- portions of the Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
- distribute the object code for the work under the terms of Section
- 6. Any executables containing that work also fall under Section 6,
- whether or not they are linked directly with the Library itself.
-
- 6. As an exception to the Sections above, you may also compile or
- link a "work that uses the Library" with the Library to produce a
- work containing portions of the Library, and distribute that work
- under terms of your choice, provided that the terms permit
- modification of the work for the customer's own use and reverse
- engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
- Library is used in it and that the Library and its use are covered
- by this License. You must supply a copy of this License. If the
- work during execution displays copyright notices, you must include
- the copyright notice for the Library among them, as well as a
- reference directing the user to the copy of this License. Also,
- you must do one of these things:
-
- a. Accompany the work with the complete corresponding
- machine-readable source code for the Library including
- whatever changes were used in the work (which must be
- distributed under Sections 1 and 2 above); and, if the work
- is an executable linked with the Library, with the complete
- machine-readable "work that uses the Library", as object code
- and/or source code, so that the user can modify the Library
- and then relink to produce a modified executable containing
- the modified Library. (It is understood that the user who
- changes the contents of definitions files in the Library will
- not necessarily be able to recompile the application to use
- the modified definitions.)
-
- b. Accompany the work with a written offer, valid for at least
- three years, to give the same user the materials specified in
- Subsection 6a, above, for a charge no more than the cost of
- performing this distribution.
-
- c. If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the
- above specified materials from the same place.
-
- d. Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
- Library" must include any data and utility programs needed for
- reproducing the executable from it. However, as a special
- exception, the source code distributed need not include anything
- that is normally distributed (in either source or binary form)
- with the major components (compiler, kernel, and so on) of the
- operating system on which the executable runs, unless that
- component itself accompanies the executable.
-
- It may happen that this requirement contradicts the license
- restrictions of other proprietary libraries that do not normally
- accompany the operating system. Such a contradiction means you
- cannot use both them and the Library together in an executable
- that you distribute.
-
- 7. You may place library facilities that are a work based on the
- Library side-by-side in a single library together with other
- library facilities not covered by this License, and distribute
- such a combined library, provided that the separate distribution
- of the work based on the Library and of the other library
- facilities is otherwise permitted, and provided that you do these
- two things:
-
- a. Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b. Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same
- work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute the
- Library except as expressly provided under this License. Any
- attempt otherwise to copy, modify, sublicense, link with, or
- distribute the Library is void, and will automatically terminate
- your rights under this License. However, parties who have
- received copies, or rights, from you under this License will not
- have their licenses terminated so long as such parties remain in
- full compliance.
-
- 9. You are not required to accept this License, since you have not
- signed it. However, nothing else grants you permission to modify
- or distribute the Library or its derivative works. These actions
- are prohibited by law if you do not accept this License.
- Therefore, by modifying or distributing the Library (or any work
- based on the Library), you indicate your acceptance of this
- License to do so, and all its terms and conditions for copying,
- distributing or modifying the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
- Library), the recipient automatically receives a license from the
- original licensor to copy, distribute, link with or modify the
- Library subject to these terms and conditions. You may not impose
- any further restrictions on the recipients' exercise of the rights
- granted herein. You are not responsible for enforcing compliance
- by third parties to this License.
-
- 11. If, as a consequence of a court judgment or allegation of patent
- infringement or for any other reason (not limited to patent
- issues), conditions are imposed on you (whether by court order,
- agreement or otherwise) that contradict the conditions of this
- License, they do not excuse you from the conditions of this
- License. If you cannot distribute so as to satisfy simultaneously
- your obligations under this License and any other pertinent
- obligations, then as a consequence you may not distribute the
- Library at all. For example, if a patent license would not permit
- royalty-free redistribution of the Library by all those who
- receive copies directly or indirectly through you, then the only
- way you could satisfy both it and this License would be to refrain
- entirely from distribution of the Library.
-
- If any portion of this section is held invalid or unenforceable
- under any particular circumstance, the balance of the section is
- intended to apply, and the section as a whole is intended to apply
- in other circumstances.
-
- It is not the purpose of this section to induce you to infringe any
- patents or other property right claims or to contest validity of
- any such claims; this section has the sole purpose of protecting
- the integrity of the free software distribution system which is
- implemented by public license practices. Many people have made
- generous contributions to the wide range of software distributed
- through that system in reliance on consistent application of that
- system; it is up to the author/donor to decide if he or she is
- willing to distribute software through any other system and a
- licensee cannot impose that choice.
-
- This section is intended to make thoroughly clear what is believed
- to be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
- certain countries either by patents or by copyrighted interfaces,
- the original copyright holder who places the Library under this
- License may add an explicit geographical distribution limitation
- excluding those countries, so that distribution is permitted only
- in or among countries not thus excluded. In such case, this
- License incorporates the limitation as if written in the body of
- this License.
-
- 13. The Free Software Foundation may publish revised and/or new
- versions of the Library General Public License from time to time.
- Such new versions will be similar in spirit to the present version,
- but may differ in detail to address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
- Library specifies a version number of this License which applies
- to it and "any later version", you have the option of following
- the terms and conditions either of that version or of any later
- version published by the Free Software Foundation. If the Library
- does not specify a license version number, you may choose any
- version ever published by the Free Software Foundation.
-
- 14. If you wish to incorporate parts of the Library into other free
- programs whose distribution conditions are incompatible with these,
- write to the author to ask for permission. For software which is
- copyrighted by the Free Software Foundation, write to the Free
- Software Foundation; we sometimes make exceptions for this. Our
- decision will be guided by the two goals of preserving the free
- status of all derivatives of our free software and of promoting
- the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
- WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE
- LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
- HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT
- WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
- NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
- FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
- QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE
- LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
- SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
- WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
- MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE
- LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
- INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
- INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF
- DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
- OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY
- OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
- ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
-How to Apply These Terms to Your New Libraries
-==============================================
-
- If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change. You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of
-the ordinary General Public License).
-
- To apply these terms, attach the following notices to the library.
-It is safest to attach them to the start of each source file to most
-effectively convey the exclusion of warranty; and each file should have
-at least the "copyright" line and a pointer to where the full notice is
-found.
-
- ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES.
- Copyright (C) YEAR NAME OF AUTHOR
-

- Linuxthreads - POSIX 1003.1c kernel threads for Linux
-
- Copyright 1996, 1997 Xavier Leroy (Xavier.Leroy@inria.fr)
-
-
-DESCRIPTION:
-
-This is release 0.7 (late beta) of LinuxThreads, a BiCapitalized
-implementation of the Posix 1003.1c "pthread" interface for Linux.
-
-LinuxThreads provides kernel-level threads: each thread is a separate
-Unix process, sharing its address space with the other threads through
-the new system call clone(). Scheduling between threads is handled by
-the kernel scheduler, just like scheduling between Unix processes.
-
-
-REQUIREMENTS:
-
-- Linux version 2.0 and up (requires the new clone() system call
- and the new realtime scheduler).
-
-- For Intel platforms: libc 5.2.18 or later is required.
- 5.2.18 or 5.4.12 or later are recommended;
- 5.3.12 and 5.4.7 have problems (see the FAQ.html file for more info).
-
-- Also supports glibc 2 (a.k.a. libc 6), which actually comes with
- a specially-adapted version of this library.
-
-- Currently supports Intel, Alpha, Sparc, Motorola 68k, ARM and MIPS
- platforms.
-
-- Multiprocessors are supported.
-
-
-INSTALLATION:
-
-- Edit the Makefile, set the variables in the "Configuration" section.
-
-- Do "make".
-
-- Do "make install".
-
-
-USING LINUXTHREADS:
-
- gcc -D_REENTRANT ... -lpthread
-
-A complete set of manual pages is included. Also see the subdirectory
-Examples/ for some sample programs.
-
-
-STATUS:
-
-- All functions in the Posix 1003.1c base interface implemented.
- Also supports priority scheduling.
-
-- For users of libc 5 (H.J.Lu's libc), a number of C library functions
- are reimplemented or wrapped to make them thread-safe, including:
- * malloc functions
- * stdio functions (define _REENTRANT before including <stdio.h>)
- * per-thread errno variable (define _REENTRANT before including <errno.h>)
- * directory reading functions (opendir(), etc)
- * sleep()
- * gmtime(), localtime()
-
- New library functions provided:
- * flockfile(), funlockfile(), ftrylockfile()
- * reentrant versions of network database functions (gethostbyname_r(), etc)
- and password functions (getpwnam_r(), etc).
-
-- libc 6 (glibc 2) provides much better thread support than libc 5,
- and comes with a specially-adapted version of LinuxThreads.
- For serious multithreaded programming, you should consider switching
- to glibc 2. It is available from ftp.gnu.org:/pub/gnu and its mirrors.
-
-
-WARNING:
-
-Many existing libraries are not compatible with LinuxThreads,
-either because they are not inherently thread-safe, or because they
-have not been compiled with the -D_REENTRANT. For more info, see the
-FAQ.html file in this directory.
-
-A prime example of the latter is Xlib. If you link it with
-LinuxThreads, you'll probably get an "unknown 0 error" very
-early. This is just a consequence of the Xlib binaries using the
-global variable "errno" to fetch error codes, while LinuxThreads and
-the C library use the per-thread "errno" location.
-
-See the file README.Xfree3.3 for info on how to compile the Xfree 3.3
-libraries to make them compatible with LinuxThreads.
-
-
-KNOWN BUGS AND LIMITATIONS:
-
-- Threads share pretty much everything they should share according
- to the standard: memory space, file descriptors, signal handlers,
- current working directory, etc. One thing that they do not share
- is their pid's and parent pid's. According to the standard, they
- should have the same, but that's one thing we cannot achieve
- in this implementation (until the CLONE_PID flag to clone() becomes
- usable).
-
-- The current implementation uses the two signals SIGUSR1 and SIGUSR2,
- so user-level code cannot employ them. Ideally, there should be two
- signals reserved for this library. One signal is used for restarting
- threads blocked on mutexes or conditions; the other is for thread
- cancellation.
-
- *** This is not anymore true when the application runs on a kernel
- newer than approximately 2.1.60.
-
-- The stacks for the threads are allocated high in the memory space,
- below the stack of the initial process, and spaced 2M apart.
- Stacks are allocated with the "grow on demand" flag, so they don't
- use much virtual space initially (4k, currently), but can grow
- up to 2M if needed.
-
- Reserving such a large address space for each thread means that,
- on a 32-bit architecture, no more than about 1000 threads can
- coexist (assuming a 2Gb address space for user processes),
- but this is reasonable, since each thread uses up one entry in the
- kernel's process table, which is usually limited to 512 processes.
-
- Another potential problem of the "grow on demand" scheme is that
- nothing prevents the user from mmap'ing something in the 2M address
- window reserved for a thread stack, possibly causing later extensions of
- that stack to fail. Mapping at fixed addresses should be avoided
- when using this library.
-
-- Signal handling does not fully conform to the Posix standard,
- due to the fact that threads are here distinct processes that can be
- sent signals individually, so there's no notion of sending a signal
- to "the" process (the collection of all threads).
- More precisely, here is a summary of the standard requirements
- and how they are met by the implementation:
-
- 1- Synchronous signals (generated by the thread execution, e.g. SIGFPE)
- are delivered to the thread that raised them.
- (OK.)
-
- 2- A fatal asynchronous signal terminates all threads in the process.
- (OK. The thread manager notices when a thread dies on a signal
- and kills all other threads with the same signal.)
-
- 3- An asynchronous signal will be delivered to one of the threads
- of the program which does not block the signal (it is unspecified
- which).
- (No, the signal is delivered to the thread it's been sent to,
- based on the pid of the thread. If that thread is currently
- blocking the signal, the signal remains pending.)
-
- 4- The signal will be delivered to at most one thread.
- (OK, except for signals generated from the terminal or sent to
- the process group, which will be delivered to all threads.)
-
-- The current implementation of the MIPS support assumes a MIPS ISA II
- processor or better. These processors support atomic operations by
- ll/sc instructions. Older R2000/R3000 series processors are not
- supported yet; support for these will have higher overhead.
-
-- The current implementation of the ARM support assumes that the SWP
- (atomic swap register with memory) instruction is available. This is
- the case for all processors except for the ARM1 and ARM2. On StrongARM,
- the SWP instruction does not bypass the cache, so multi-processor support
- will be more troublesome.

-XFree-3.2 (files: README.X11.patch R6.1pl1-3.2.diff.gz cfont32.tgz).
-
-Untar the xc-?.tar.gz files in a directory called XF3.2 and apply
-the XFree-3.2 patches as described in README.X11.patch or use the
-whole XFree86 source.
-
-Now apply the thread patch with
-
-patch -p0 < XF3.2.xc.diff
-
-Go to the XF3.2/xc directory and make the whole thing:
-nice make World >& world.log &
-tail -f world.log
-
-Wait a few hours or interrupt the process after the shared libs
-are made. The shared libs are:
-
-XF3.2/xc/lib/ICE/libICE.so.6.0*
-XF3.2/xc/lib/PEX5/libPEX5.so.6.0*
-XF3.2/xc/lib/SM/libSM.so.6.0*
-XF3.2/xc/lib/X11/libX11.so.6.1*
-XF3.2/xc/lib/XIE/libXIE.so.6.0*
-XF3.2/xc/lib/XThrStub/libXThrStub.so.6.0*
-XF3.2/xc/lib/Xaw/libXaw.so.6.1*
-XF3.2/xc/lib/Xext/libXext.so.6.1*
-XF3.2/xc/lib/Xi/libXi.so.6.0*
-XF3.2/xc/lib/Xmu/libXmu.so.6.0*
-XF3.2/xc/lib/Xt/libXt.so.6.0*
-XF3.2/xc/lib/Xtst/libXtst.so.6.1*
-
-(The Program dga didn't compile, but I have not check out why.)
-
-Now you can copy the resulting libs
-
-cp XF3.2/xc/lib/*/*.so.?.? /usr/X11R6/lib/
-
-and create some links
-
-cd /usr/X11R6/lib/
-ln -s libXThrStub.so.6.0 libXThrStub.so.6
-ln -s libXThrStub.so.6 libXThrStub.so
-
-or use make install (not tested, and needs new configuration).
-
-It is possible with the libXThrSub to compile X11 programs without linking
-libpthread to them and not necessary to recompile already installed
-unthreaded X11 programs, because libXThrSub keeps the dynamic linker quit.
-On the other hand you can link libpthread to a X11 program to use threads.
-
-I used linux 2.0.23 and libc 5.4.7 .

-primitives, synchronization objects, and so forth. It also implements
-POSIX 1003.1b semaphores (not to be confused with System V semaphores).
-
-The threads operations (@samp{pthread_*}) do not use @var{errno}.
-Instead they return an error code directly. The semaphore operations do
-use @var{errno}.

-@deftypefun int pthread_create (pthread_t * @var{thread}, pthread_attr_t * @var{attr}, void * (*@var{start_routine})(void *), void * @var{arg})
-@code{pthread_create} creates a new thread of control that executes
-concurrently with the calling thread. The new thread calls the
-function @var{start_routine}, passing it @var{arg} as first argument. The
-new thread terminates either explicitly, by calling @code{pthread_exit},
-or implicitly, by returning from the @var{start_routine} function. The
-latter case is equivalent to calling @code{pthread_exit} with the result
-returned by @var{start_routine} as exit code.
-
-The @var{attr} argument specifies thread attributes to be applied to the
-new thread. @xref{Thread Attributes}, for details. The @var{attr}
-argument can also be @code{NULL}, in which case default attributes are
-used: the created thread is joinable (not detached) and has an ordinary
-(not realtime) scheduling policy.
-
-On success, the identifier of the newly created thread is stored in the
-location pointed by the @var{thread} argument, and a 0 is returned. On
-error, a non-zero error code is returned.
-
-This function may return the following errors:
-@table @code
-@item EAGAIN
-Not enough system resources to create a process for the new thread,
-or more than @code{PTHREAD_THREADS_MAX} threads are already active.

-@deftypefun void pthread_exit (void *@var{retval})
-@code{pthread_exit} terminates the execution of the calling thread. All
-cleanup handlers (@pxref{Cleanup Handlers}) that have been set for the
-calling thread with @code{pthread_cleanup_push} are executed in reverse
-order (the most recently pushed handler is executed first). Finalization
-functions for thread-specific data are then called for all keys that
-have non-@code{NULL} values associated with them in the calling thread
-(@pxref{Thread-Specific Data}). Finally, execution of the calling
-thread is stopped.
-
-The @var{retval} argument is the return value of the thread. It can be
-retrieved from another thread using @code{pthread_join}.

-@deftypefun int pthread_cancel (pthread_t @var{thread})
-
-@code{pthread_cancel} sends a cancellation request to the thread denoted
-by the @var{thread} argument. If there is no such thread,
-@code{pthread_cancel} fails and returns @code{ESRCH}. Otherwise it
-returns 0. @xref{Cancellation}, for details.
-@end deftypefun

-@comment POSIX
-@deftypefun int pthread_join (pthread_t @var{th}, void **thread_@var{return})
-@code{pthread_join} suspends the execution of the calling thread until
-the thread identified by @var{th} terminates, either by calling
-@code{pthread_exit} or by being canceled.
-
-If @var{thread_return} is not @code{NULL}, the return value of @var{th}
-is stored in the location pointed to by @var{thread_return}. The return
-value of @var{th} is either the argument it gave to @code{pthread_exit},
-or @code{PTHREAD_CANCELED} if @var{th} was canceled.
-
-The joined thread @code{th} must be in the joinable state: it must not
-have been detached using @code{pthread_detach} or the
-@code{PTHREAD_CREATE_DETACHED} attribute to @code{pthread_create}.
-
-When a joinable thread terminates, its memory resources (thread
-descriptor and stack) are not deallocated until another thread performs
-@code{pthread_join} on it. Therefore, @code{pthread_join} must be called
-once for each joinable thread created to avoid memory leaks.
-
-At most one thread can wait for the termination of a given
-thread. Calling @code{pthread_join} on a thread @var{th} on which
-another thread is already waiting for termination returns an error.
-
-@code{pthread_join} is a cancellation point. If a thread is canceled
-while suspended in @code{pthread_join}, the thread execution resumes
-immediately and the cancellation is executed without waiting for the
-@var{th} thread to terminate. If cancellation occurs during
-@code{pthread_join}, the @var{th} thread remains not joined.
-
-On success, the return value of @var{th} is stored in the location
-pointed to by @var{thread_return}, and 0 is returned. On error, one of
-the following values is returned:
-@table @code
-@item ESRCH
-No thread could be found corresponding to that specified by @var{th}.
-@item EINVAL
-The @var{th} thread has been detached, or another thread is already
-waiting on termination of @var{th}.

-Threads have a number of attributes that may be set at creation time.
-This is done by filling a thread attribute object @var{attr} of type
-@code{pthread_attr_t}, then passing it as second argument to
-@code{pthread_create}. Passing @code{NULL} is equivalent to passing a
-thread attribute object with all attributes set to their default values.
-
-Attribute objects are consulted only when creating a new thread. The
-same attribute object can be used for creating several threads.
-Modifying an attribute object after a call to @code{pthread_create} does
-not change the attributes of the thread previously created.

-
-Each attribute @var{attrname} (see below for a list of all attributes)

-@table @samp
-@item detachstate
-Choose whether the thread is created in the joinable state (value
-@code{PTHREAD_CREATE_JOINABLE}) or in the detached state
-(@code{PTHREAD_CREATE_DETACHED}). The default is
-@code{PTHREAD_CREATE_JOINABLE}.
-
-In the joinable state, another thread can synchronize on the thread
-termination and recover its termination code using @code{pthread_join},
-but some of the thread resources are kept allocated after the thread
-terminates, and reclaimed only when another thread performs
-@code{pthread_join} on that thread.
-
-In the detached state, the thread resources are immediately freed when
-it terminates, but @code{pthread_join} cannot be used to synchronize on
-the thread termination.
-
-A thread created in the joinable state can later be put in the detached
-thread using @code{pthread_detach}.
-
-@item schedpolicy
-Select the scheduling policy for the thread: one of @code{SCHED_OTHER}
-(regular, non-realtime scheduling), @code{SCHED_RR} (realtime,
-round-robin) or @code{SCHED_FIFO} (realtime, first-in first-out).
-The default is @code{SCHED_OTHER}.
-@c Not doc'd in our manual: FIXME.
-@c See @code{sched_setpolicy} for more information on scheduling policies.
-
-The realtime scheduling policies @code{SCHED_RR} and @code{SCHED_FIFO}
-are available only to processes with superuser privileges.
-@code{pthread_attr_setschedparam} will fail and return @code{ENOTSUP} if
-you try to set a realtime policy when you are unprivileged.
-
-The scheduling policy of a thread can be changed after creation with
-@code{pthread_setschedparam}.
-
-@item schedparam
-Change the scheduling parameter (the scheduling priority)
-for the thread. The default is 0.
-
-This attribute is not significant if the scheduling policy is
-@code{SCHED_OTHER}; it only matters for the realtime policies
-@code{SCHED_RR} and @code{SCHED_FIFO}.
-
-The scheduling priority of a thread can be changed after creation with
-@code{pthread_setschedparam}.
-
-@item inheritsched
-Choose whether the scheduling policy and scheduling parameter for the
-newly created thread are determined by the values of the
-@var{schedpolicy} and @var{schedparam} attributes (value
-@code{PTHREAD_EXPLICIT_SCHED}) or are inherited from the parent thread
-(value @code{PTHREAD_INHERIT_SCHED}). The default is
-@code{PTHREAD_EXPLICIT_SCHED}.
-
-@item scope
-Choose the scheduling contention scope for the created thread. The
-default is @code{PTHREAD_SCOPE_SYSTEM}, meaning that the threads contend
-for CPU time with all processes running on the machine. In particular,
-thread priorities are interpreted relative to the priorities of all
-other processes on the machine. The other possibility,
-@code{PTHREAD_SCOPE_PROCESS}, means that scheduling contention occurs
-only between the threads of the running process: thread priorities are
-interpreted relative to the priorities of the other threads of the
-process, regardless of the priorities of other processes.
-
-@code{PTHREAD_SCOPE_PROCESS} is not supported in LinuxThreads. If you
-try to set the scope to this value, @code{pthread_attr_setscope} will
-fail and return @code{ENOTSUP}.
-
-@item stackaddr
-Provide an address for an application managed stack. The size of the
-stack must be at least @code{PTHREAD_STACK_MIN}.
-
-@item stacksize
-Change the size of the stack created for the thread. The value defines
-the minimum stack size, in bytes.
-
-If the value exceeds the system's maximum stack size, or is smaller
-than @code{PTHREAD_STACK_MIN}, @code{pthread_attr_setstacksize} will
-fail and return @code{EINVAL}.
-
-@item stack
-Provide both the address and size of an application managed stack to
-use for the new thread. The base of the memory area is @var{stackaddr}
-with the size of the memory area, @var{stacksize}, measured in bytes.
-
-If the value of @var{stacksize} is less than @code{PTHREAD_STACK_MIN},
-or greater than the system's maximum stack size, or if the value of
-@var{stackaddr} lacks the proper alignment, @code{pthread_attr_setstack}
-will fail and return @code{EINVAL}.
-
-@item guardsize
-Change the minimum size in bytes of the guard area for the thread's
-stack. The default size is a single page. If this value is set, it
-will be rounded up to the nearest page size. If the value is set to 0,
-a guard area will not be created for this thread. The space allocated
-for the guard area is used to catch stack overflow. Therefore, when
-allocating large structures on the stack, a larger guard area may be
-required to catch a stack overflow.
-
-If the caller is managing their own stacks (if the @code{stackaddr}
-attribute has been set), then the @code{guardsize} attribute is ignored.
-
-If the value exceeds the @code{stacksize}, @code{pthread_atrr_setguardsize}
-will fail and return @code{EINVAL}.
-@end table
-
-@node Cancellation
-@section Cancellation
-
-Cancellation is the mechanism by which a thread can terminate the
-execution of another thread. More precisely, a thread can send a
-cancellation request to another thread. Depending on its settings, the
-target thread can then either ignore the request, honor it immediately,
-or defer it till it reaches a cancellation point. When threads are
-first created by @code{pthread_create}, they always defer cancellation
-requests.
-
-When a thread eventually honors a cancellation request, it behaves as if
-@code{pthread_exit(PTHREAD_CANCELED)} was called. All cleanup handlers
-are executed in reverse order, finalization functions for
-thread-specific data are called, and finally the thread stops executing.
-If the canceled thread was joinable, the return value
-@code{PTHREAD_CANCELED} is provided to whichever thread calls
-@var{pthread_join} on it. See @code{pthread_exit} for more information.
-
-Cancellation points are the points where the thread checks for pending
-cancellation requests and performs them. The POSIX threads functions
-@code{pthread_join}, @code{pthread_cond_wait},
-@code{pthread_cond_timedwait}, @code{pthread_testcancel},
-@code{sem_wait}, and @code{sigwait} are cancellation points. In
-addition, these system calls are cancellation points:
-
-@multitable @columnfractions .33 .33 .33
-@item @t{accept} @tab @t{open} @tab @t{sendmsg}
-@item @t{close} @tab @t{pause} @tab @t{sendto}

-@item @t{msync} @tab @t{send} @tab @t{write}
-@item @t{nanosleep}
-@end multitable
-
-@noindent
-All library functions that call these functions (such as
-@code{printf}) are also cancellation points.
-
-@comment pthread.h
-@comment POSIX
-@deftypefun int pthread_setcancelstate (int @var{state}, int *@var{oldstate})
-@code{pthread_setcancelstate} changes the cancellation state for the
-calling thread -- that is, whether cancellation requests are ignored or
-not. The @var{state} argument is the new cancellation state: either
-@code{PTHREAD_CANCEL_ENABLE} to enable cancellation, or
-@code{PTHREAD_CANCEL_DISABLE} to disable cancellation (cancellation
-requests are ignored).
-
-If @var{oldstate} is not @code{NULL}, the previous cancellation state is
-stored in the location pointed to by @var{oldstate}, and can thus be

-@node Cleanup Handlers
-@section Cleanup Handlers
-
-Cleanup handlers are functions that get called when a thread terminates,
-either by calling @code{pthread_exit} or because of
-cancellation. Cleanup handlers are installed and removed following a
-stack-like discipline.
-
-The purpose of cleanup handlers is to free the resources that a thread
-may hold at the time it terminates. In particular, if a thread exits or
-is canceled while it owns a locked mutex, the mutex will remain locked
-forever and prevent other threads from executing normally. The best way
-to avoid this is, just before locking the mutex, to install a cleanup
-handler whose effect is to unlock the mutex. Cleanup handlers can be
-used similarly to free blocks allocated with @code{malloc} or close file
-descriptors on thread termination.
-
-Here is how to lock a mutex @var{mut} in such a way that it will be
-unlocked if the thread is canceled while @var{mut} is locked:
-
-@smallexample
-pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
-pthread_mutex_lock(&mut);
-/* do some work */
-pthread_mutex_unlock(&mut);
-pthread_cleanup_pop(0);
-@end smallexample
-
-Equivalently, the last two lines can be replaced by
-
-@smallexample
-pthread_cleanup_pop(1);
-@end smallexample
-
-Notice that the code above is safe only in deferred cancellation mode
-(see @code{pthread_setcanceltype}). In asynchronous cancellation mode, a
-cancellation can occur between @code{pthread_cleanup_push} and
-@code{pthread_mutex_lock}, or between @code{pthread_mutex_unlock} and
-@code{pthread_cleanup_pop}, resulting in both cases in the thread trying
-to unlock a mutex not locked by the current thread. This is the main
-reason why asynchronous cancellation is difficult to use.
-
-If the code above must also work in asynchronous cancellation mode,
-then it must switch to deferred mode for locking and unlocking the
-mutex:
-
-@smallexample
-pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype);
-pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
-pthread_mutex_lock(&mut);
-/* do some work */
-pthread_cleanup_pop(1);
-pthread_setcanceltype(oldtype, NULL);
-@end smallexample
-
-The code above can be rewritten in a more compact and efficient way,
-using the non-portable functions @code{pthread_cleanup_push_defer_np}
-and @code{pthread_cleanup_pop_restore_np}:
-
-@smallexample
-pthread_cleanup_push_defer_np(pthread_mutex_unlock, (void *) &mut);
-pthread_mutex_lock(&mut);
-/* do some work */
-pthread_cleanup_pop_restore_np(1);

-matching @code{pthread_cleanup_pop}, the function @var{routine} will be
-called with arguments @var{arg} when the thread terminates, either
-through @code{pthread_exit} or by cancellation. If several cleanup
-handlers are active at that point, they are called in LIFO order: the

-@node Mutexes
-@section Mutexes
-
-A mutex is a MUTual EXclusion device, and is useful for protecting
-shared data structures from concurrent modifications, and implementing
-critical sections and monitors.
-
-A mutex has two possible states: unlocked (not owned by any thread),
-and locked (owned by one thread). A mutex can never be owned by two
-different threads simultaneously. A thread attempting to lock a mutex
-that is already locked by another thread is suspended until the owning
-thread unlocks the mutex first.
-
-None of the mutex functions is a cancellation point, not even
-@code{pthread_mutex_lock}, in spite of the fact that it can suspend a
-thread for arbitrary durations. This way, the status of mutexes at
-cancellation points is predictable, allowing cancellation handlers to
-unlock precisely those mutexes that need to be unlocked before the
-thread stops executing. Consequently, threads using deferred
-cancellation should never hold a mutex for extended periods of time.
-
-It is not safe to call mutex functions from a signal handler. In
-particular, calling @code{pthread_mutex_lock} or
-@code{pthread_mutex_unlock} from a signal handler may deadlock the
-calling thread.

-@node Thread-Specific Data
-@section Thread-Specific Data
-
-Programs often need global or static variables that have different
-values in different threads. Since threads share one memory space, this
-cannot be achieved with regular variables. Thread-specific data is the
-POSIX threads answer to this need.
-
-Each thread possesses a private memory block, the thread-specific data
-area, or TSD area for short. This area is indexed by TSD keys. The TSD
-area associates values of type @code{void *} to TSD keys. TSD keys are
-common to all threads, but the value associated with a given TSD key can
-be different in each thread.
-
-For concreteness, the TSD areas can be viewed as arrays of @code{void *}
-pointers, TSD keys as integer indices into these arrays, and the value
-of a TSD key as the value of the corresponding array element in the
-calling thread.
-
-When a thread is created, its TSD area initially associates @code{NULL}
-with all keys.

-@code{PTHREAD_KEYS_MAX} on the number of keys allocated at a given
-time. The value initially associated with the returned key is
-@code{NULL} in all currently executing threads.
-
-The @var{destr_function} argument, if not @code{NULL}, specifies a
-destructor function associated with the key. When a thread terminates
-via @code{pthread_exit} or by cancellation, @var{destr_function} is
-called on the value associated with the key in that thread. The
-@var{destr_function} is not called if a key is deleted with
-@code{pthread_key_delete} or a value is changed with
-@code{pthread_setspecific}. The order in which destructor functions are
-called at thread termination time is unspecified.
-
-Before the destructor function is called, the @code{NULL} value is
-associated with the key in the current thread. A destructor function
-might, however, re-associate non-@code{NULL} values to that key or some
-other key. To deal with this, if after all the destructors have been
-called for all non-@code{NULL} values, there are still some
-non-@code{NULL} values with associated destructors, then the process is
-repeated. The LinuxThreads implementation stops the process after

-@end deftypefun
-
-For @code{sigwait} to work reliably, the signals being waited for must be
-blocked in all threads, not only in the calling thread, since
-otherwise the POSIX semantics for signal delivery do not guarantee
-that it's the thread doing the @code{sigwait} that will receive the signal.
-The best way to achieve this is block those signals before any threads
-are created, and never unblock them in the program other than by
-calling @code{sigwait}.
-
-Signal handling in LinuxThreads departs significantly from the POSIX
-standard. According to the standard, ``asynchronous'' (external) signals
-are addressed to the whole process (the collection of all threads),
-which then delivers them to one particular thread. The thread that
-actually receives the signal is any thread that does not currently block
-the signal.
-
-In LinuxThreads, each thread is actually a kernel process with its own
-PID, so external signals are always directed to one particular thread.
-If, for instance, another thread is blocked in @code{sigwait} on that
-signal, it will not be restarted.
-
-The LinuxThreads implementation of @code{sigwait} installs dummy signal
-handlers for the signals in @var{set} for the duration of the
-wait. Since signal handlers are shared between all threads, other
-threads must not attach their own signal handlers to these signals, or
-alternatively they should all block these signals (which is recommended
-anyway).

-@node Threads and Fork
-@section Threads and Fork
-
-It's not intuitively obvious what should happen when a multi-threaded POSIX
-process calls @code{fork}. Not only are the semantics tricky, but you may
-need to write code that does the right thing at fork time even if that code
-doesn't use the @code{fork} function. Moreover, you need to be aware of
-interaction between @code{fork} and some library features like
-@code{pthread_once} and stdio streams.
-
-When @code{fork} is called by one of the threads of a process, it creates a new
-process which is copy of the calling process. Effectively, in addition to
-copying certain system objects, the function takes a snapshot of the memory
-areas of the parent process, and creates identical areas in the child.
-To make matters more complicated, with threads it's possible for two or more
-threads to concurrently call fork to create two or more child processes.
-
-The child process has a copy of the address space of the parent, but it does
-not inherit any of its threads. Execution of the child process is carried out
-by a new thread which returns from @code{fork} function with a return value of
-zero; it is the only thread in the child process. Because threads are not
-inherited across fork, issues arise. At the time of the call to @code{fork},
-threads in the parent process other than the one calling @code{fork} may have
-been executing critical regions of code. As a result, the child process may
-get a copy of objects that are not in a well-defined state. This potential
-problem affects all components of the program.
-
-Any program component which will continue being used in a child process must
-correctly handle its state during @code{fork}. For this purpose, the POSIX
-interface provides the special function @code{pthread_atfork} for installing
-pointers to handler functions which are called from within @code{fork}.
-
-@comment pthread.h
-@comment POSIX
-@deftypefun int pthread_atfork (void (*@var{prepare})(void), void (*@var{parent})(void), void (*@var{child})(void))
-
-@code{pthread_atfork} registers handler functions to be called just
-before and just after a new process is created with @code{fork}. The
-@var{prepare} handler will be called from the parent process, just
-before the new process is created. The @var{parent} handler will be
-called from the parent process, just before @code{fork} returns. The
-@var{child} handler will be called from the child process, just before
-@code{fork} returns.
-
-@code{pthread_atfork} returns 0 on success and a non-zero error code on
-error.
-
-One or more of the three handlers @var{prepare}, @var{parent} and
-@var{child} can be given as @code{NULL}, meaning that no handler needs
-to be called at the corresponding point.
-
-@code{pthread_atfork} can be called several times to install several
-sets of handlers. At @code{fork} time, the @var{prepare} handlers are
-called in LIFO order (last added with @code{pthread_atfork}, first
-called before @code{fork}), while the @var{parent} and @var{child}
-handlers are called in FIFO order (first added, first called).
-
-If there is insufficient memory available to register the handlers,
-@code{pthread_atfork} fails and returns @code{ENOMEM}. Otherwise it
-returns 0.
-
-The functions @code{fork} and @code{pthread_atfork} must not be regarded as
-reentrant from the context of the handlers. That is to say, if a
-@code{pthread_atfork} handler invoked from within @code{fork} calls
-@code{pthread_atfork} or @code{fork}, the behavior is undefined.
-
-Registering a triplet of handlers is an atomic operation with respect to fork.
-If new handlers are registered at about the same time as a fork occurs, either
-all three handlers will be called, or none of them will be called.
-
-The handlers are inherited by the child process, and there is no
-way to remove them, short of using @code{exec} to load a new
-pocess image.
-
-@end deftypefun
-
-To understand the purpose of @code{pthread_atfork}, recall that
-@code{fork} duplicates the whole memory space, including mutexes in
-their current locking state, but only the calling thread: other threads
-are not running in the child process. The mutexes are not usable after
-the @code{fork} and must be initialized with @code{pthread_mutex_init}
-in the child process. This is a limitation of the current
-implementation and might or might not be present in future versions.
-
-To avoid this, install handlers with @code{pthread_atfork} as follows: have the
-@var{prepare} handler lock the mutexes (in locking order), and the
-@var{parent} handler unlock the mutexes. The @var{child} handler should reset
-the mutexes using @code{pthread_mutex_init}, as well as any other
-synchronization objects such as condition variables.
-
-Locking the global mutexes before the fork ensures that all other threads are
-locked out of the critical regions of code protected by those mutexes. Thus
-when @code{fork} takes a snapshot of the parent's address space, that snapshot
-will copy valid, stable data. Resetting the synchronization objects in the
-child process will ensure they are properly cleansed of any artifacts from the
-threading subsystem of the parent process. For example, a mutex may inherit
-a wait queue of threads waiting for the lock; this wait queue makes no sense
-in the child process. Initializing the mutex takes care of this.
-
-@node Streams and Fork
-@section Streams and Fork
-
-The GNU standard I/O library has an internal mutex which guards the internal
-linked list of all standard C FILE objects. This mutex is properly taken care
-of during @code{fork} so that the child receives an intact copy of the list.
-This allows the @code{fopen} function, and related stream-creating functions,
-to work correctly in the child process, since these functions need to insert
-into the list.
-
-However, the individual stream locks are not completely taken care of. Thus
-unless the multithreaded application takes special precautions in its use of
-@code{fork}, the child process might not be able to safely use the streams that
-it inherited from the parent. In general, for any given open stream in the
-parent that is to be used by the child process, the application must ensure
-that that stream is not in use by another thread when @code{fork} is called.
-Otherwise an inconsistent copy of the stream object be produced. An easy way to
-ensure this is to use @code{flockfile} to lock the stream prior to calling
-@code{fork} and then unlock it with @code{funlockfile} inside the parent
-process, provided that the parent's threads properly honor these locks.
-Nothing special needs to be done in the child process, since the library
-internally resets all stream locks.
-
-Note that the stream locks are not shared between the parent and child.
-For example, even if you ensure that, say, the stream @code{stdout} is properly
-treated and can be safely used in the child, the stream locks do not provide
-an exclusion mechanism between the parent and child. If both processes write
-to @code{stdout}, strangely interleaved output may result regardless of
-the explicit use of @code{flockfile} or implicit locks.
-
-Also note that these provisions are a GNU extension; other systems might not
-provide any way for streams to be used in the child of a multithreaded process.
-POSIX requires that such a child process confines itself to calling only
-asynchronous safe functions, which excludes much of the library, including
-standard I/O.

-.TH PTHREAD_ATFORK 3 LinuxThreads
-
-.SH NAME
-pthread_atfork \- register handlers to be called at fork(2) time
-
-.SH SYNOPSIS
-#include <pthread.h>
-
-int pthread_atfork(void (*prepare)(void), void (*parent)(void), void (*child)(void));
-
-.SH DESCRIPTION
-
-!pthread_atfork! registers handler functions to be called just before
-and just after a new process is created with !fork!(2). The |prepare|
-handler will be called from the parent process, just before the new
-process is created. The |parent| handler will be called from the parent
-process, just before !fork!(2) returns. The |child| handler will be
-called from the child process, just before !fork!(2) returns.
-
-One or several of the three handlers |prepare|, |parent| and |child|
-can be given as !NULL!, meaning that no handler needs to be called at
-the corresponding point.
-
-!pthread_atfork! can be called several times to install several sets
-of handlers. At !fork!(2) time, the |prepare| handlers are called in
-LIFO order (last added with !pthread_atfork!, first called before !fork!),
-while the |parent| and |child| handlers are called in FIFO order
-(first added, first called).
-
-To understand the purpose of !pthread_atfork!, recall that !fork!(2)
-duplicates the whole memory space, including mutexes in their current
-locking state, but only the calling thread: other threads are not
-running in the child process. The mutexes are not usable after the
-!fork! and must be initialized with |pthread_mutex_init| in the child
-process. This is a limitation of the current implementation and might
-or might not be present in future versions.
-
-.SH "RETURN VALUE"
-
-!pthread_atfork! returns 0 on success and a non-zero error code on error.
-
-.SH ERRORS
-.TP
-!ENOMEM!
-insufficient memory available to register the handlers.

-
-int pthread_attr_getscope(const pthread_attr_t *attr, int *scope);
-
-.SH DESCRIPTION
-
-Setting attributes for threads is achieved by filling a
-thread attribute object |attr| of type !pthread_attr_t!, then passing it as
-second argument to !pthread_create!(3). Passing !NULL! is equivalent to
-passing a thread attribute object with all attributes set to their
-default values.
-
-!pthread_attr_init! initializes the thread attribute object |attr| and
-fills it with default values for the attributes. (The default values
-are listed below for each attribute.)
-
-Each attribute |attrname| (see below for a list of all attributes) can
-be individually set using the function !pthread_attr_set!|attrname|
-and retrieved using the function !pthread_attr_get!|attrname|.
-
-!pthread_attr_destroy! destroys a thread attribute object, which
-must not be reused until it is reinitialized. !pthread_attr_destroy!
-does nothing in the LinuxThreads implementation.
-
-Attribute objects are consulted only when creating a new thread. The
-same attribute object can be used for creating several
-threads. Modifying an attribute object after a call to
-!pthread_create! does not change the attributes of the thread
-previously created.
-
-The following thread attributes are supported:
-
-.SS detachstate
-
-Control whether the thread is created in the joinable state (value
-!PTHREAD_CREATE_JOINABLE!) or in the detached state
-(!PTHREAD_CREATE_DETACHED!).
-
-Default value: !PTHREAD_CREATE_JOINABLE!.
-
-In the joinable state, another thread can synchronize on the thread
-termination and recover its termination code using !pthread_join!(3),
-but some of the thread resources are kept allocated after the thread
-terminates, and reclaimed only when another thread performs
-!pthread_join!(3) on that thread.
-
-In the detached state, the thread resources are immediately freed when
-it terminates, but !pthread_join!(3) cannot be used to synchronize on
-the thread termination.
-
-A thread created in the joinable state can later be put in the
-detached thread using !pthread_detach!(3).
-
-.SS schedpolicy
-
-Select the scheduling policy for the thread: one of
-!SCHED_OTHER! (regular, non-realtime scheduling),
-!SCHED_RR! (realtime, round-robin) or
-!SCHED_FIFO! (realtime, first-in first-out). See
-!sched_setpolicy!(2) for more information on scheduling policies.
-
-Default value: !SCHED_OTHER!.
-
-The realtime scheduling policies !SCHED_RR! and !SCHED_FIFO! are
-available only to processes with superuser privileges.
-
-The scheduling policy of a thread can be changed after creation with
-!pthread_setschedparam!(3).
-
-.SS schedparam
-
-Contain the scheduling parameters (essentially, the scheduling
-priority) for the thread. See !sched_setparam!(2) for more information
-on scheduling parameters.
-
-Default value: priority is 0.
-
-This attribute is not significant if the scheduling policy is !SCHED_OTHER!;
-it only matters for the realtime policies !SCHED_RR! and !SCHED_FIFO!.
-
-The scheduling priority of a thread can be changed after creation with
-!pthread_setschedparam!(3).
-
-.SS inheritsched
-
-Indicate whether the scheduling policy and scheduling parameters for
-the newly created thread are determined by the values of the
-|schedpolicy| and |schedparam| attributes (value
-!PTHREAD_EXPLICIT_SCHED!) or are inherited from the parent thread
-(value !PTHREAD_INHERIT_SCHED!).
-
-Default value: !PTHREAD_EXPLICIT_SCHED!.
-
-.SS scope
-
-Define the scheduling contention scope for the created thread. The
-only value supported in the LinuxThreads implementation is
-!PTHREAD_SCOPE_SYSTEM!, meaning that the threads contend for CPU time
-with all processes running on the machine. In particular, thread
-priorities are interpreted relative to the priorities of all other
-processes on the machine. The other value specified by the standard,
-!PTHREAD_SCOPE_PROCESS!, means that scheduling contention occurs only
-between the threads of the running process: thread priorities are
-interpreted relative to the priorities of the other threads of the
-process, regardless of the priorities of other processes.
-!PTHREAD_SCOPE_PROCESS! is not supported in LinuxThreads.
-
-Default value: !PTHREAD_SCOPE_SYSTEM!.
-
-.SH "RETURN VALUE"
-
-All functions return 0 on success and a non-zero error code on error.
-On success, the !pthread_attr_get!|attrname| functions also store the
-current value of the attribute |attrname| in the location pointed to
-by their second argument.
-
-.SH ERRORS
-
-The !pthread_attr_setdetachstate! function returns the following error
-codes on error:
-.RS
-.TP
-!EINVAL!
-the specified |detachstate| is not one of !PTHREAD_CREATE_JOINABLE! or
-!PTHREAD_CREATE_DETACHED!.

-
-.SH NAME
-pthread_cancel, pthread_setcancelstate, pthread_setcanceltype, pthread_testcancel \- thread cancellation
-
-.SH SYNOPSIS
-#include <pthread.h>
-
-int pthread_cancel(pthread_t thread);
-
-int pthread_setcancelstate(int state, int *oldstate);
-
-int pthread_setcanceltype(int type, int *oldtype);
-
-void pthread_testcancel(void);
-
-.SH DESCRIPTION
-
-Cancellation is the mechanism by which a thread can terminate the
-execution of another thread. More precisely, a thread can send a
-cancellation request to another thread. Depending on its settings, the
-target thread can then either ignore the request, honor it
-immediately, or defer it till it reaches a cancellation point.
-
-When a thread eventually honors a cancellation request, it performs as
-if !pthread_exit(PTHREAD_CANCELED)! has been called at that point:
-all cleanup handlers are executed in reverse order, finalization
-functions for thread-specific data are called, and finally the thread
-stops executing with the return value !PTHREAD_CANCELED!. See
-!pthread_exit!(3) for more information.
-
-!pthread_cancel! sends a cancellation request to the thread denoted
-by the |thread| argument.
-
-!pthread_setcancelstate! changes the cancellation state for the
-calling thread -- that is, whether cancellation requests are ignored
-or not. The |state| argument is the new cancellation state: either
-!PTHREAD_CANCEL_ENABLE! to enable cancellation, or
-!PTHREAD_CANCEL_DISABLE! to disable cancellation (cancellation
-requests are ignored). If |oldstate| is not !NULL!, the previous
-cancellation state is stored in the location pointed to by |oldstate|,
-and can thus be restored later by another call to
-!pthread_setcancelstate!.
-
-!pthread_setcanceltype! changes the type of responses to cancellation
-requests for the calling thread: asynchronous (immediate) or deferred.
-The |type| argument is the new cancellation type: either
-!PTHREAD_CANCEL_ASYNCHRONOUS! to cancel the calling thread as soon as
-the cancellation request is received, or !PTHREAD_CANCEL_DEFERRED! to
-keep the cancellation request pending until the next cancellation
-point. If |oldtype| is not !NULL!, the previous
-cancellation state is stored in the location pointed to by |oldtype|,
-and can thus be restored later by another call to
-!pthread_setcanceltype!.
-
-Threads are always created by !pthread_create!(3) with cancellation
-enabled and deferred. That is, the initial cancellation state is
-!PTHREAD_CANCEL_ENABLE! and the initial type is
-!PTHREAD_CANCEL_DEFERRED!.
-
-Cancellation points are those points in the program execution where a
-test for pending cancellation requests is performed and cancellation
-is executed if positive. The following POSIX threads functions
-are cancellation points:
-
-!pthread_join!(3)
-.br
-!pthread_cond_wait!(3)
-.br
-!pthread_cond_timedwait!(3)
-.br
-!pthread_testcancel!(3)
-.br
-!sem_wait!(3)
-.br
-!sigwait!(3)
-
-All other POSIX threads functions are guaranteed not to be
-cancellation points. That is, they never perform cancellation in
-deferred cancellation mode.
-
-!pthread_testcancel! does nothing except testing for pending
-cancellation and executing it. Its purpose is to introduce explicit
-checks for cancellation in long sequences of code that do not call
-cancellation point functions otherwise.
-
-.SH "RETURN VALUE"
-
-!pthread_cancel!, !pthread_setcancelstate! and
-!pthread_setcanceltype! return 0 on success and a non-zero error code
-on error.

-
-POSIX specifies that a number of system calls (basically, all
-system calls that may block, such as !read!(2), !write!(2), !wait!(2),
-etc.) and library functions that may call these system calls (e.g.
-!fprintf!(3)) are cancellation points. LinuxThreads is not yet
-integrated enough with the C library to implement this, and thus none
-of the C library functions is a cancellation point.
-
-For system calls at least, there is a workaround. Cancellation
-requests are transmitted to the target thread by sending it a
-signal. That signal will interrupt all blocking system calls, causing
-them to return immediately with the !EINTR! error. So, checking for
-cancellation during a !read! system call, for instance, can be
-achieved as follows:

-
-.SH NAME
-pthread_cleanup_push, pthread_cleanup_pop, pthread_cleanup_push_defer_np, pthread_cleanup_pop_restore_np \- install and remove cleanup handlers
-
-.SH SYNOPSIS
-#include <pthread.h>
-
-void pthread_cleanup_push(void (*routine) (void *), void *arg);
-
-void pthread_cleanup_pop(int execute);
-
-void pthread_cleanup_push_defer_np(void (*routine) (void *), void *arg);
-
-void pthread_cleanup_pop_restore_np(int execute);
-
-.SH DESCRIPTION
-
-Cleanup handlers are functions that get called when a thread
-terminates, either by calling !pthread_exit!(3) or because of
-cancellation. Cleanup handlers are installed and removed following a
-stack-like discipline.
-
-The purpose of cleanup handlers is to free the resources that a thread
-may hold at the time it terminates. In particular, if a thread
-exits or is cancelled while it owns a locked mutex, the mutex will
-remain locked forever and prevent other threads from executing
-normally. The best way to avoid this is, just before locking the
-mutex, to install a cleanup handler whose effect is to unlock the
-mutex. Cleanup handlers can be used similarly to free blocks allocated
-with !malloc!(3) or close file descriptors on thread termination.
-
-!pthread_cleanup_push! installs the |routine| function with argument
-|arg| as a cleanup handler. From this point on to the matching
-!pthread_cleanup_pop!, the function |routine| will be called with
-arguments |arg| when the thread terminates, either through !pthread_exit!(3)
-or by cancellation. If several cleanup handlers are active at that
-point, they are called in LIFO order: the most recently installed
-handler is called first.
-
-!pthread_cleanup_pop! removes the most recently installed cleanup
-handler. If the |execute| argument is not 0, it also executes the
-handler, by calling the |routine| function with arguments |arg|. If
-the |execute| argument is 0, the handler is only removed but not
-executed.
-
-Matching pairs of !pthread_cleanup_push! and !pthread_cleanup_pop!
-must occur in the same function, at the same level of block nesting.
-Actually, !pthread_cleanup_push! and !pthread_cleanup_pop! are macros,
-and the expansion of !pthread_cleanup_push! introduces an open brace !{!
-with the matching closing brace !}! being introduced by the expansion
-of the matching !pthread_cleanup_pop!.
-
-!pthread_cleanup_push_defer_np! is a non-portable extension that
-combines !pthread_cleanup_push! and !pthread_setcanceltype!(3).
-It pushes a cleanup handler just as !pthread_cleanup_push! does, but
-also saves the current cancellation type and sets it to deferred
-cancellation. This ensures that the cleanup mechanism is effective
-even if the thread was initially in asynchronous cancellation mode.
-
-!pthread_cleanup_pop_restore_np! pops a cleanup handler introduced by
-!pthread_cleanup_push_defer_np!, and restores the cancellation type to
-its value at the time !pthread_cleanup_push_defer_np! was called.
-
-!pthread_cleanup_push_defer_np! and !pthread_cleanup_pop_restore_np!
-must occur in matching pairs, at the same level of block nesting.

-.SH EXAMPLE
-
-Here is how to lock a mutex |mut| in such a way that it will be
-unlocked if the thread is canceled while |mut| is locked:
-
-.RS
-.ft 3
-.nf
-.sp
-pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
-pthread_mutex_lock(&mut);
-/* do some work */
-pthread_mutex_unlock(&mut);
-pthread_cleanup_pop(0);
-.ft
-.LP

-
-Equivalently, the last two lines can be replaced by
-
-.RS
-.ft 3
-.nf
-.sp
-pthread_cleanup_pop(1);
-.ft
-.LP
-.RE
-.fi
-
-Notice that the code above is safe only in deferred cancellation mode
-(see !pthread_setcanceltype!(3)). In asynchronous cancellation mode,
-a cancellation can occur between !pthread_cleanup_push! and
-!pthread_mutex_lock!, or between !pthread_mutex_unlock! and
-!pthread_cleanup_pop!, resulting in both cases in the thread trying to
-unlock a mutex not locked by the current thread. This is the main
-reason why asynchronous cancellation is difficult to use.
-
-If the code above must also work in asynchronous cancellation mode,
-then it must switch to deferred mode for locking and unlocking the
-mutex:

-pthread_cond_init, pthread_cond_destroy, pthread_cond_signal, pthread_cond_broadcast, pthread_cond_wait, pthread_cond_timedwait \- operations on conditions
-
-.SH SYNOPSIS
-#include <pthread.h>
-
-pthread_cond_t cond = PTHREAD_COND_INITIALIZER;
-
-int pthread_cond_init(pthread_cond_t *cond, pthread_condattr_t *cond_attr);
-

-
-int pthread_cond_destroy(pthread_cond_t *cond);
-
-.SH DESCRIPTION
-
-A condition (short for ``condition variable'') is a synchronization
-device that allows threads to suspend execution and relinquish the
-processors until some predicate on shared data is satisfied. The basic
-operations on conditions are: signal the condition (when the
-predicate becomes true), and wait for the condition, suspending the
-thread execution until another thread signals the condition.
-
-A condition variable must always be associated with a mutex, to avoid
-the race condition where a thread prepares to wait on a condition
-variable and another thread signals the condition just before the
-first thread actually waits on it.
-
-!pthread_cond_init! initializes the condition variable |cond|, using the
-condition attributes specified in |cond_attr|, or default attributes
-if |cond_attr| is !NULL!. The LinuxThreads implementation supports no
-attributes for conditions, hence the |cond_attr| parameter is actually
-ignored.
-
-Variables of type !pthread_cond_t! can also be initialized
-statically, using the constant !PTHREAD_COND_INITIALIZER!.
-
-!pthread_cond_signal! restarts one of the threads that are waiting on
-the condition variable |cond|. If no threads are waiting on |cond|,
-nothing happens. If several threads are waiting on |cond|, exactly one
-is restarted, but it is not specified which.
-
-!pthread_cond_broadcast! restarts all the threads that are waiting on
-the condition variable |cond|. Nothing happens if no threads are
-waiting on |cond|.
-
-!pthread_cond_wait! atomically unlocks the |mutex| (as per
-!pthread_unlock_mutex!) and waits for the condition variable |cond| to
-be signaled. The thread execution is suspended and does not consume
-any CPU time until the condition variable is signaled. The |mutex|
-must be locked by the calling thread on entrance to
-!pthread_cond_wait!. Before returning to the calling thread,
-!pthread_cond_wait! re-acquires |mutex| (as per !pthread_lock_mutex!).
-
-Unlocking the mutex and suspending on the condition variable is done
-atomically. Thus, if all threads always acquire the mutex before
-signaling the condition, this guarantees that the condition cannot be
-signaled (and thus ignored) between the time a thread locks the mutex
-and the time it waits on the condition variable.
-
-!pthread_cond_timedwait! atomically unlocks |mutex| and waits on
-|cond|, as !pthread_cond_wait! does, but it also bounds the duration
-of the wait. If |cond| has not been signaled within the amount of time
-specified by |abstime|, the mutex |mutex| is re-acquired and
-!pthread_cond_timedwait! returns the error !ETIMEDOUT!.
-The |abstime| parameter specifies an absolute time, with the same
-origin as !time!(2) and !gettimeofday!(2): an |abstime| of 0
-corresponds to 00:00:00 GMT, January 1, 1970.
-
-!pthread_cond_destroy! destroys a condition variable, freeing the
-resources it might hold. No threads must be waiting on the condition
-variable on entrance to !pthread_cond_destroy!. In the LinuxThreads
-implementation, no resources are associated with condition variables,
-thus !pthread_cond_destroy! actually does nothing except checking that
-the condition has no waiting threads.
-
-.SH CANCELLATION
-
-!pthread_cond_wait! and !pthread_cond_timedwait! are cancellation
-points. If a thread is cancelled while suspended in one of these
-functions, the thread immediately resumes execution, then locks again
-the |mutex| argument to !pthread_cond_wait! and
-!pthread_cond_timedwait!, and finally executes the cancellation.
-Consequently, cleanup handlers are assured that |mutex| is locked when
-they are called.
-
-.SH "ASYNC-SIGNAL SAFETY"
-
-The condition functions are not async-signal safe, and should not be
-called from a signal handler. In particular, calling
-!pthread_cond_signal! or !pthread_cond_broadcast! from a signal
-handler may deadlock the calling thread.
-
-.SH "RETURN VALUE"
-
-All condition variable functions return 0 on success and a non-zero
-error code on error.
-
-.SH ERRORS
-
-!pthread_cond_init!, !pthread_cond_signal!, !pthread_cond_broadcast!,
-and !pthread_cond_wait! never return an error code.
-
-The !pthread_cond_timedwait! function returns the following error codes
-on error:
-.RS
-.TP
-!ETIMEDOUT!
-the condition variable was not signaled until the timeout specified by
-|abstime|
-
-.TP
-!EINTR!
-!pthread_cond_timedwait! was interrupted by a signal
-.RE
-
-The !pthread_cond_destroy! function returns the following error code
-on error:
-.RS
-.TP
-!EBUSY!

-
-.SH DESCRIPTION
-!pthread_create! creates a new thread of control that executes
-concurrently with the calling thread. The new thread applies the
-function |start_routine| passing it |arg| as first argument. The new
-thread terminates either explicitly, by calling !pthread_exit!(3),
-or implicitly, by returning from the |start_routine| function. The
-latter case is equivalent to calling !pthread_exit!(3) with the result
-returned by |start_routine| as exit code.
-
-The |attr| argument specifies thread attributes to be applied to the
-new thread. See !pthread_attr_init!(3) for a complete list of thread
-attributes. The |attr| argument can also be !NULL!, in which case
-default attributes are used: the created thread is joinable (not

-
-int pthread_join(pthread_t th, void **thread_return);
-
-.SH DESCRIPTION
-!pthread_join! suspends the execution of the calling thread until the

-or by being cancelled.
-
-If |thread_return| is not !NULL!, the return value of |th| is stored

-
-The joined thread !th! must be in the joinable state: it must not have
-been detached using !pthread_detach!(3) or the
-!PTHREAD_CREATE_DETACHED! attribute to !pthread_create!(3).
-
-When a joinable thread terminates, its memory resources (thread
-descriptor and stack) are not deallocated until another thread
-performs !pthread_join! on it. Therefore, !pthread_join! must be
-called once for each joinable thread created to avoid memory leaks.
-
-At most one thread can wait for the termination of a given
-thread. Calling !pthread_join! on a thread |th| on which another
-thread is already waiting for termination returns an error.
-
-.SH CANCELLATION
-
-!pthread_join! is a cancellation point. If a thread is canceled while
-suspended in !pthread_join!, the thread execution resumes immediately
-and the cancellation is executed without waiting for the |th| thread
-to terminate. If cancellation occurs during !pthread_join!, the |th|
-thread remains not joined.

-.TH PTHREAD_SPECIFIC 3 LinuxThreads
-
-.SH NAME
-pthread_key_create, pthread_key_delete, pthread_setspecific, pthread_getspecific \- management of thread-specific data
-
-.SH SYNOPSIS
-#include <pthread.h>
-
-int pthread_key_create(pthread_key_t *key, void (*destr_function) (void *));
-
-int pthread_key_delete(pthread_key_t key);
-
-int pthread_setspecific(pthread_key_t key, const void *pointer);
-
-void * pthread_getspecific(pthread_key_t key);
-
-.SH DESCRIPTION
-
-Programs often need global or static variables that have different
-values in different threads. Since threads share one memory space,
-this cannot be achieved with regular variables. Thread-specific data
-is the POSIX threads answer to this need.
-
-Each thread possesses a private memory block, the thread-specific data
-area, or TSD area for short. This area is indexed by TSD keys. The TSD
-area associates values of type !void *! to TSD keys. TSD keys are
-common to all threads, but the value associated with a given TSD key
-can be different in each thread.
-
-For concreteness, the TSD areas can be viewed as arrays of !void *!
-pointers, TSD keys as integer indices into these arrays, and the value
-of a TSD key as the value of the corresponding array element in the
-calling thread.
-
-When a thread is created, its TSD area initially associates !NULL!
-with all keys.
-
-!pthread_key_create! allocates a new TSD key. The key is stored in the
-location pointed to by |key|. There is a limit of !PTHREAD_KEYS_MAX!
-on the number of keys allocated at a given time. The value initially
-associated with the returned key is !NULL! in all currently executing
-threads.
-
-The |destr_function| argument, if not !NULL!, specifies a destructor
-function associated with the key. When a thread terminates via
-!pthread_exit! or by cancellation, |destr_function| is called with
-arguments the value associated with the key in that thread. The
-|destr_function| is not called if that value is !NULL!. The order in
-which destructor functions are called at thread termination time is
-unspecified.
-
-Before the destructor function is called, the !NULL! value is
-associated with the key in the current thread. A destructor function
-might, however, re-associate non-!NULL! values to that key or some
-other key. To deal with this, if after all the destructors have been
-called for all non-!NULL! values, there are still some non-!NULL!
-values with associated destructors, then the process is repeated. The
-LinuxThreads implementation stops the process after
-!PTHREAD_DESTRUCTOR_ITERATIONS! iterations, even if some non-!NULL!
-values with associated descriptors remain. Other implementations may
-loop indefinitely.
-
-!pthread_key_delete! deallocates a TSD key. It does not check whether
-non-!NULL! values are associated with that key in the currently
-executing threads, nor call the destructor function associated with
-the key.
-
-!pthread_setspecific! changes the value associated with |key| in the
-calling thread, storing the given |pointer| instead.
-
-!pthread_getspecific! returns the value currently associated with
-|key| in the calling thread.
-
-.SH "RETURN VALUE"
-
-!pthread_key_create!, !pthread_key_delete!, and !pthread_setspecific!
-return 0 on success and a non-zero error code on failure. If
-successful, !pthread_key_create! stores the newly allocated key in the
-location pointed to by its |key| argument.
-
-!pthread_getspecific! returns the value associated with |key| on
-success, and !NULL! on error.

-!pthread_kill_other_threads_np! is a non-portable LinuxThreads extension.

-e.g. !execve!(2).
-
-Termination of the other threads is not performed through

-cancellation type are ignored, and the cleanup handlers are not
-executed in the terminated threads.

-
-.SH DESCRIPTION
-A mutex is a MUTual EXclusion device, and is useful for protecting
-shared data structures from concurrent modifications, and implementing
-critical sections and monitors.
-
-A mutex has two possible states: unlocked (not owned by any thread),
-and locked (owned by one thread). A mutex can never be owned by two
-different threads simultaneously. A thread attempting to lock a mutex
-that is already locked by another thread is suspended until the owning
-thread unlocks the mutex first.
-
-!pthread_mutex_init! initializes the mutex object pointed to by
-|mutex| according to the mutex attributes specified in |mutexattr|.
-If |mutexattr| is !NULL!, default attributes are used instead.
-
-The LinuxThreads implementation supports only one mutex attributes,
-the |mutex kind|, which is either ``fast'', ``recursive'', or
-``error checking''. The kind of a mutex determines whether
-it can be locked again by a thread that already owns it.
-The default kind is ``fast''. See !pthread_mutexattr_init!(3) for more
-information on mutex attributes.
-
-Variables of type !pthread_mutex_t! can also be initialized
-statically, using the constants !PTHREAD_MUTEX_INITIALIZER! (for fast
-mutexes), !PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP! (for recursive
-mutexes), and !PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP! (for error checking
-mutexes).
-
-!pthread_mutex_lock! locks the given mutex. If the mutex is currently
-unlocked, it becomes locked and owned by the calling thread, and
-!pthread_mutex_lock! returns immediately. If the mutex is already
-locked by another thread, !pthread_mutex_lock! suspends the calling
-thread until the mutex is unlocked.
-
-If the mutex is already locked by the calling thread, the behavior of
-!pthread_mutex_lock! depends on the kind of the mutex. If the mutex is
-of the ``fast'' kind, the calling thread is suspended until the mutex
-is unlocked, thus effectively causing the calling thread to
-deadlock. If the mutex is of the ``error checking'' kind,
-!pthread_mutex_lock! returns immediately with the error code !EDEADLK!.
-If the mutex is of the ``recursive'' kind, !pthread_mutex_lock!
-succeeds and returns immediately, recording the number of times the
-calling thread has locked the mutex. An equal number of
-!pthread_mutex_unlock! operations must be performed before the mutex
-returns to the unlocked state.
-
-!pthread_mutex_trylock! behaves identically to !pthread_mutex_lock!,
-except that it does not block the calling thread if the mutex is
-already locked by another thread (or by the calling thread in the case
-of a ``fast'' mutex). Instead, !pthread_mutex_trylock! returns
-immediately with the error code !EBUSY!.
-
-!pthread_mutex_unlock! unlocks the given mutex. The mutex is assumed
-to be locked and owned by the calling thread on entrance to
-!pthread_mutex_unlock!. If the mutex is of the ``fast'' kind,
-!pthread_mutex_unlock! always returns it to the unlocked state. If it
-is of the ``recursive'' kind, it decrements the locking count of the
-mutex (number of !pthread_mutex_lock! operations performed on it by
-the calling thread), and only when this count reaches zero is the
-mutex actually unlocked.
-
-On ``error checking'' mutexes, !pthread_mutex_unlock! actually checks
-at run-time that the mutex is locked on entrance, and that it was
-locked by the same thread that is now calling !pthread_mutex_unlock!.
-If these conditions are not met, an error code is returned and the
-mutex remains unchanged. ``Fast'' and ``recursive'' mutexes perform
-no such checks, thus allowing a locked mutex to be unlocked by a
-thread other than its owner. This is non-portable behavior and must
-not be relied upon.
-
-!pthread_mutex_destroy! destroys a mutex object, freeing the resources
-it might hold. The mutex must be unlocked on entrance. In the
-LinuxThreads implementation, no resources are associated with mutex
-objects, thus !pthread_mutex_destroy! actually does nothing except
-checking that the mutex is unlocked.
-
-.SH CANCELLATION
-
-None of the mutex functions is a cancellation point, not even
-!pthread_mutex_lock!, in spite of the fact that it can suspend a
-thread for arbitrary durations. This way, the status of mutexes at
-cancellation points is predictable, allowing cancellation handlers to
-unlock precisely those mutexes that need to be unlocked before the
-thread stops executing. Consequently, threads using deferred
-cancellation should never hold a mutex for extended periods of time.
-
-.SH "ASYNC-SIGNAL SAFETY"
-
-The mutex functions are not async-signal safe. What this means is that
-they should not be called from a signal handler. In particular,
-calling !pthread_mutex_lock! or !pthread_mutex_unlock! from a signal
-handler may deadlock the calling thread.
-
-.SH "RETURN VALUE"
-
-!pthread_mutex_init! always returns 0. The other mutex functions
-return 0 on success and a non-zero error code on error.
-
-.SH ERRORS
-
-The !pthread_mutex_lock! function returns the following error code
-on error:
-.RS
-.TP
-!EINVAL!
-the mutex has not been properly initialized.
-
-.TP
-!EDEADLK!
-the mutex is already locked by the calling thread

-.SH NAME
-pthread_mutexattr_init, pthread_mutexattr_destroy, pthread_mutexattr_settype, pthread_mutexattr_gettype \- mutex creation attributes
-
-.SH SYNOPSIS
-#include <pthread.h>
-
-int pthread_mutexattr_init(pthread_mutexattr_t *attr);
-
-int pthread_mutexattr_destroy(pthread_mutexattr_t *attr);
-
-int pthread_mutexattr_settype(pthread_mutexattr_t *attr, int kind);
-
-int pthread_mutexattr_gettype(const pthread_mutexattr_t *attr, int *kind);
-
-.SH DESCRIPTION
-
-Mutex attributes can be specified at mutex creation time, by passing a
-mutex attribute object as second argument to !pthread_mutex_init!(3).
-Passing !NULL! is equivalent to passing a mutex attribute object with
-all attributes set to their default values.
-
-!pthread_mutexattr_init! initializes the mutex attribute object |attr|
-and fills it with default values for the attributes.
-
-!pthread_mutexattr_destroy! destroys a mutex attribute object, which
-must not be reused until it is reinitialized. !pthread_mutexattr_destroy!
-does nothing in the LinuxThreads implementation.
-
-LinuxThreads supports only one mutex attribute: the mutex kind, which
-is either !PTHREAD_MUTEX_FAST_NP! for ``fast'' mutexes,
-!PTHREAD_MUTEX_RECURSIVE_NP! for ``recursive'' mutexes,
-or !PTHREAD_MUTEX_ERRORCHECK_NP! for ``error checking'' mutexes.
-As the !NP! suffix indicates, this is a non-portable extension to the
-POSIX standard and should not be employed in portable programs.
-
-The mutex kind determines what happens if a thread attempts to lock a
-mutex it already owns with !pthread_mutex_lock!(3). If the mutex is of
-the ``fast'' kind, !pthread_mutex_lock!(3) simply suspends the calling
-thread forever. If the mutex is of the ``error checking'' kind,
-!pthread_mutex_lock!(3) returns immediately with the error code
-!EDEADLK!. If the mutex is of the ``recursive'' kind, the call to
-!pthread_mutex_lock!(3) returns immediately with a success return
-code. The number of times the thread owning the mutex has locked it is
-recorded in the mutex. The owning thread must call
-!pthread_mutex_unlock!(3) the same number of times before the mutex
-returns to the unlocked state.
-
-The default mutex kind is ``fast'', that is, !PTHREAD_MUTEX_FAST_NP!.
-
-!pthread_mutexattr_settype! sets the mutex kind attribute in |attr|
-to the value specified by |kind|.
-
-!pthread_mutexattr_gettype! retrieves the current value of the
-mutex kind attribute in |attr| and stores it in the location pointed
-to by |kind|.
-
-.SH "RETURN VALUE"
-!pthread_mutexattr_init!, !pthread_mutexattr_destroy! and
-!pthread_mutexattr_gettype! always return 0.
-
-!pthread_mutexattr_settype! returns 0 on success and a non-zero
-error code on error.
-
-.SH ERRORS
-
-On error, !pthread_mutexattr_settype! returns the following error code:

-
-.SH NOTES
-
-For !sigwait! to work reliably, the signals being waited for must be
-blocked in all threads, not only in the calling thread, since
-otherwise the POSIX semantics for signal delivery do not guarantee
-that it's the thread doing the !sigwait! that will receive the signal.
-The best way to achieve this is block those signals before any threads
-are created, and never unblock them in the program other than by
-calling !sigwait!.
-
-.SH BUGS
-
-Signal handling in LinuxThreads departs significantly from the POSIX
-standard. According to the standard, ``asynchronous'' (external)
-signals are addressed to the whole process (the collection of all
-threads), which then delivers them to one particular thread. The
-thread that actually receives the signal is any thread that does
-not currently block the signal.
-
-In LinuxThreads, each thread is actually a kernel process with its own
-PID, so external signals are always directed to one particular thread.
-If, for instance, another thread is blocked in !sigwait! on that
-signal, it will not be restarted.
-
-The LinuxThreads implementation of !sigwait! installs dummy signal
-handlers for the signals in |set| for the duration of the wait. Since
-signal handlers are shared between all threads, other threads must not
-attach their own signal handlers to these signals, or alternatively
-they should all block these signals (which is recommended anyway --
-see the Notes section).

-
-.SH NAME
-sem_init, sem_wait, sem_trywait, sem_post, sem_getvalue, sem_destroy \- operations on semaphores
-
-.SH SYNOPSIS
-#include <semaphore.h>
-
-int sem_init(sem_t *sem, int pshared, unsigned int value);
-
-int sem_wait(sem_t * sem);
-
-int sem_trywait(sem_t * sem);
-
-int sem_post(sem_t * sem);
-
-int sem_getvalue(sem_t * sem, int * sval);
-
-int sem_destroy(sem_t * sem);
-
-.SH DESCRIPTION
-This manual page documents POSIX 1003.1b semaphores, not to be
-confused with SystemV semaphores as described in !ipc!(5), !semctl!(2)
-and !semop!(2).
-
-Semaphores are counters for resources shared between threads. The
-basic operations on semaphores are: increment the counter atomically,
-and wait until the counter is non-null and decrement it atomically.
-
-!sem_init! initializes the semaphore object pointed to by |sem|. The
-count associated with the semaphore is set initially to |value|. The
-|pshared| argument indicates whether the semaphore is local to the
-current process (|pshared| is zero) or is to be shared between several
-processes (|pshared| is not zero). LinuxThreads currently does not
-support process-shared semaphores, thus !sem_init! always returns with
-error !ENOSYS! if |pshared| is not zero.
-
-!sem_wait! suspends the calling thread until the semaphore pointed to
-by |sem| has non-zero count. It then atomically decreases the
-semaphore count.
-
-!sem_trywait! is a non-blocking variant of !sem_wait!. If the
-semaphore pointed to by |sem| has non-zero count, the count is
-atomically decreased and !sem_trywait! immediately returns 0.
-If the semaphore count is zero, !sem_trywait! immediately returns with
-error !EAGAIN!.
-
-!sem_post! atomically increases the count of the semaphore pointed to
-by |sem|. This function never blocks and can safely be used in
-asynchronous signal handlers.
-
-!sem_getvalue! stores in the location pointed to by |sval| the current
-count of the semaphore |sem|.
-
-!sem_destroy! destroys a semaphore object, freeing the resources it
-might hold. No threads should be waiting on the semaphore at the time
-!sem_destroy! is called. In the LinuxThreads implementation, no
-resources are associated with semaphore objects, thus !sem_destroy!
-actually does nothing except checking that no thread is waiting on the
-semaphore.
-
-.SH CANCELLATION
-
-!sem_wait! is a cancellation point.
-
-.SH "ASYNC-SIGNAL SAFETY"
-
-On processors supporting atomic compare-and-swap (Intel 486, Pentium
-and later, Alpha, PowerPC, MIPS II, Motorola 68k), the !sem_post!
-function is async-signal safe and can therefore be
-called from signal handlers. This is the only thread synchronization
-function provided by POSIX threads that is async-signal safe.
-
-On the Intel 386 and the Sparc, the current LinuxThreads
-implementation of !sem_post! is not async-signal safe by lack of the

-.SH "RETURN VALUE"
-
-The !sem_wait! and !sem_getvalue! functions always return 0.
-All other semaphore functions return 0 on success and -1 on error, in
-addition to writing an error code in !errno!.
-
-.SH ERRORS
-
-The !sem_init! function sets !errno! to the following codes on error:
-.RS
-.TP
-!EINVAL!
-|value| exceeds the maximal counter value !SEM_VALUE_MAX!
-.TP
-!ENOSYS!
-|pshared| is not zero
-.RE
-
-The !sem_trywait! function sets !errno! to the following error code on error:
-.RS
-.TP
-!EAGAIN!
-the semaphore count is currently 0
-.RE
-
-The !sem_post! function sets !errno! to the following error code on error:
-.RS
-.TP
-!ERANGE!
-after incrementation, the semaphore value would exceed !SEM_VALUE_MAX!
-(the semaphore count is left unchanged in this case)
-.RE
-
-The !sem_destroy! function sets !errno! to the following error code on error:
-.RS
-.TP
-!EBUSY!
-some threads are currently blocked waiting on the semaphore.
