+The GNU C library contains an NSS module for the Hesiod name service.
+Hesiod is a general name service for a variety of applications and is
+based on the Berkeley Internet Name Daemon (BIND).
+
+Introduction
+============
+
+The Hesiod NSS module implements access to all relevant standard
+Hesiod types, which means that Hesiod can be used for the `group',
+`passwd' and `services' databases. There is however a restriction.
+In the same way that it is impossible to use `gethostent()' to iterate
+over all the data provided by DNS, it is not possible to scan the
+entire Hesiod database by means of `getgrent()', `getpwent()' and
+`getservent()'. Besides, Hesiod only provides support for looking up
+services by name and not for looking them up by port. In essence this
+means that the Hesiod name service is only consulted as a result of
+one of the following function calls:
+
+ * getgrname(), getgrgid()
+ * getpwname(), getpwuid()
+ * getservbyname()
+
+and their reentrant counterparts.
+
+
+Configuring your systems
+========================
+
+Configuring your systems to make use use the Hesiod name service
+requires one or more of the following steps, depending on whether you
+are already running Hesiod in your network.
+
+Configuring NSS
+---------------
+
+First you should modify the file `/etc/nsswitch.conf' to tell
+NSS for which database you want to use the Hesiod name service. If
+you want to use Hesiod for all databases it can handle your
+configuration file could look like this:
+
+ # /etc/nsswitch.conf
+ #
+ # Example configuration of GNU Name Service Switch functionality.
+ #
+
+ passwd: db files hesiod
+ group: db files hesiod
+ shadow: db files
+
+ hosts: files dns
+ networks: files dns
+
+ protocols: db files
+ services: db files hesiod
+ ethers: db files
+ rpc: db files
+
+For more information on NSS, please refer to the `The GNU C Library
+Reference Manual'.
+
+
+Configuring Hesiod
+------------------
+
+Next, you will have to configure Hesiod. If you are already running
+Hesiod in your network, you probably already have a file named
+`hesiod.conf' on your machines (probably as `/etc/hesiod.conf' or
+`/usr/local/etc/hesiod.conf'). The Hesiod NSS module expects this
+file to be found in the sysconfdir (`/usr/local/etc/hesiod.conf' by
+default, see the installation notes on how to change this) or in the
+location specified by the environment variable `HESIOD_CONFIG'. If
+there is no configuration file you will want to create your own. It
+should look something like:
+
+ rhs=.your.domain
+ lhs=.ns
+
+The value of rhs can be overridden by the environment variable
+HES_DOMAIN.
+
+Configuring your name servers
+-----------------------------
+
+In addition, if you are not already running Hesiod in your network,
+you need to create Hesiod information on your central name servers.
+You need to run `named' from BIND 4.9 or higher on these servers, and
+make them authoritative for the domain `ns.your.domain' with a line in
+`/etc/named.boot' reading something like:
+
+ primary ns.your.domain named.hesiod
+
+or if you are using the new BIND 8.1 or higher add something to
+`/etc/named.conf' like:
+
+ zone "ns.your.domain" {
+ type master;
+ file "named.hesiod";
+ };
+
+Then in the BIND working directory (usually `/var/named') create the
+file `named.hesiod' containing data that looks something like:
+
+ ; SOA and NS records.
+ @ IN SOA server1.your.domain admin-address.your.domain (
+ 40000 ; serial - database version number
+ 1800 ; refresh - sec servers
+ 300 ; retry - for refresh
+ 3600000 ; expire - unrefreshed data
+ 7200 ) ; min
+ NS server1.your.domain
+ NS server2.your.domain
+
+ ; Actual Hesiod data.
+ libc.group TXT "libc:*:123:gnu,gnat"
+ 123.gid CNAME libc.group
+ gnu.passwd TXT "gnu:*:4567:123:GNU:/home/gnu:/bin/bash"
+ 456.uid CNAME mark.passwd
+ nss.service TXT "nss;tcp;789;switch sw "
+ nss.service TXT "nss;udp;789;switch sw"
+
+where `libc' is an example of a group, `gnu' an example of an user,
+and `nss' an example of a service. Note that the format used to
+describe services differs from the format used in `/etc/services'.
+For more information on `named' refer to the `Name Server Operations
+Guide for BIND' that is included in the BIND distribution.
+
+
+Security
+========
+
+Note that the information stored in the Hesiod database in principle
+is publicly available. Care should be taken with including vulnerable
+information like encrypted passwords in the Hesiod database. There
+are some ways to improve security by using features provided by
+`named' (see the discussion about `secure zones' in the BIND
+documentation), but one should keep in mind that Hesiod was never
+intended to distribute passwords. In the origional design
+authenticating users was the job of the Kerberos service.
+
+
+More information
+================
+
+For more information on the Hesiod name service take a look at some of
+the papers in ftp://athena-dist.mit.edu:/pub/ATHENA/usenix and the
+documentation that accompanies the source code for the Hesiod name
+service library in ftp://athena-dist.mit.edu:/pub/ATHENA/hesiod.
+
+There is a mailing list at MIT for Hesiod users, hesiod@mit.edu. To
+get yourself on or off the list, send mail to hesiod-request@mit.edu.

+The functions to handle files in directories described so far allowed to
+retrieve all the information in small pieces or process all files in a
+directory (see @code{scandir}). Sometimes it is useful to process whole
+hierachies of directories and the contained files. The X/Open
+specification define two functions to do this. The simpler form is
+derived from an early definition in @w{System V} systems and therefore
+this function is available on SVID derived systems. The prototypes and
+required definitions can be found in the @file{ftw.h} header.
+
+Both functions of this @code{ftw} family take as one of the arguments a
+reference to a callback function. The functions must be of these types.

+Type for callback functions given to the @code{ftw} function. The first
+parameter will contain a pointer to the filename, the second parameter
+will point to an object of type @code{struct stat} which will be filled
+for the file named by the first parameter.
+
+@noindent
+The last parameter is a flag given more information about the current
+file. It can have the following values:
+
+@vindex FTW_F
+@vindex FTW_D
+@vindex FTW_NS
+@vindex FTW_DNR
+@vindex FTW_SL
+@table @code
+@item FTW_F
+The current item is a normal file or files which do not fit into one of
+the following categories. This means especially special files, sockets
+etc.
+@item FTW_D
+The current item is a directory.
+@item FTW_NS
+The @code{stat} call to fill the object pointed to by the second
+parameter failed and so the information is invalid.
+@item FTW_DNR
+The item is a directory which cannot be read.
+@item FTW_SL
+The item is a symbolic link. Since symbolic links are normally followed
+seeing this value in a @code{ftw} callback function means the referenced
+file does not exist. The situation for @code{nftw} is different.
+
+This value is only available if the program is compiled with
+@code{_BSD_SOURCE} or @code{_XOPEN_EXTENDED} defined before including
+the first header. The original SVID systems do not have symbolic links.

+The first three arguments have the same as for the @code{__ftw_func_t}
+type. A difference is that for the third argument some additional
+values are defined to allow finer differentiation:
+@table @code
+@item FTW_DP
+The current item is a directory and all subdirectories have already been

+@item FTW_SLN
+The current item is a stale symbolic link. The file it points to does
+not exist.

+
+The last parameter of the callback function is a pointer to a structure
+with some extra information as described below.
+@end deftp
+
+@deftp {Data Type} {struct FTW}
+The contained information helps to interpret the name parameter and
+gives some information about current state of the traversal of the
+directory hierachy.
+
+@table @code
+@item int base
+The value specifies which part of the filename argument given in the
+first parameter to the callback function is the name of the file. The
+rest of the string is the path to locate the file. This information is
+especially important if the @code{FTW_CHDIR} flag for @code{nftw} was
+set since then the current directory is the one the current item is
+found in.
+@item int level
+While processing the directory the functions tracks how many directories
+have been examine to find the current item. This nesting level is

+@deftypefun int ftw (const char *@var{filename}, __ftw_func_t @var{func}, int @var{descriptors})
+The @code{ftw} function calls the callback function given in the
+parameter @var{func} for every item which is found in the directory
+specified by @var{filename} and all directories below. The function
+follows symbolic links if necessary but does not process an item twice.
+If @var{filename} names no directory this item is the only object
+reported by calling the callback function.
+
+The filename given to the callback function is constructed by taking the
+@var{filename} parameter and appending the names of all passed
+directories and then the local file name. So the callback function can
+use this parameter to access the file. Before the callback function is
+called @code{ftw} calls @code{stat} for this file and passes the
+information up to the callback function. If this @code{stat} call was
+not successful the failure is indicated by setting the falg argument of
+the callback function to @code{FTW_NS}. Otherwise the flag is set
+according to the description given in the description of
+@code{__ftw_func_t} above.
+
+The callback function is expected to return @math{0} to indicate that no
+error occurred and the processing should be continued. If an error
+occurred in the callback function or the call to @code{ftw} shall return
+immediately the callback function can return a value other than
+@math{0}. This is the only correct way to stop the function. The
+program must not use @code{setjmp} or similar techniques to continue the
+program in another place. This would leave the resources allocated in
+the @code{ftw} function allocated.
+
+The @var{descriptors} parameter to the @code{ftw} function specifies how
+many file descriptors the @code{ftw} function is allowed to consume.
+The more descriptors can be used the faster the function can run. For
+each level of directories at most one descriptor is used so that for
+very deep directory hierachies the limit on open file descriptors for
+the process or the system can be exceeded. Beside this the limit on
+file descriptors is counted together for all threads in a multi-threaded
+program and therefore it is always good too limit the maximal number of
+open descriptors to a reasonable number.
+
+The return value of the @code{ftw} function is @math{0} if all callback
+function calls returned @math{0} and all actions performed by the
+@code{ftw} succeeded. If some function call failed (other than calling
+@code{stat} on an item) the function return @math{-1}. If a callback
+function returns a value other than @math{0} this value is returned as
+the return value of @code{ftw}.

+@comment ftw.h
+@comment XPG4.2
+@deftypefun int nftw (const char *@var{filename}, __nftw_func_t @var{func}, int @var{descriptors}, int @var{flag})
+The @code{nftw} functions works like the @code{ftw} functions. It calls
+the callback function @var{func} for all items it finds in the directory
+@var{filename} and below. At most @var{descriptors} file descriptors
+are consumed during the @code{nftw} call.
+
+The differences are that for one the callback function is of a different
+type. It is of type @w{@code{struct FTW *}} and provides the callback
+functions the information described above.
+
+The second difference is that @code{nftw} takes an additional fourth
+argument which is @math{0} or a combination of any of the following
+values, combined using bitwise OR.
+
+@table @code
+@item FTW_PHYS
+While traversing the directory symbolic links are not followed. I.e.,
+if this flag is given symbolic links are reported using the
+@code{FTW_SL} value for the type parameter to the callback function.
+Please note that if this flag is used the appearence of @code{FTW_SL} in
+a callback function does not mean the referenced file does not exist.
+To indicate this the extra value @code{FTW_SLN} exists.
+@item FTW_MOUNT
+The callback function is only called for items which are on the same
+mounted filesystem as the directory given as the @var{filename}
+parameter to @code{nftw}.
+@item FTW_CHDIR
+If this flag is given the current working directory is changed to the
+directory containing the reported object before the callback function is
+called.
+@item FTW_DEPTH
+If this option is given the function visits first all files and
+subdirectories before the callback function is called for the directory
+itself (depth-first processing). This also means the type flag given to
+the callback function is @code{FTW_DP} and not @code{FTW_D}.
+@end table
+
+The return value is computed in the same way as for @code{ftw}.
+@code{nftw} return @math{0} if no failure occurred in @code{nftw} and
+all callback function call return values are also @math{0}. For
+internal errors such as memory problems @math{-1} is returned and
+@var{errno} is set accordingly. If the return value of a callback
+invocation is nonzero this very same value is returned.

+@node Hash Search Function
+@section The @code{hsearch} function.
+
+The functions mentioned so far in this chapter are searching in a sorted
+or unsorted array. There are other methods to organize information
+which later should be searched. The costs of insert, delete and search
+differ. One possible implementation is using hashing tables.
+
+@comment search.h
+@comment SVID
+@deftypefun int hcreate (size_t @var{nel})
+The @code{hcreate} function creates a hashing table which can contain at
+least @var{nel} elements. There is no possibility to grow this table so
+it is necessary to choose the value for @var{nel} wisely. The used
+methods to implement this function might make it necessary to make the
+number of elements in the hashing table larger than the expected maximal
+number of elements. Hashing tables usually work inefficient if they are
+filled 80% or more. The constant access time guaranteed by hashing can
+only be achieved if few collisions exist. See Knuth's ``The Art of
+Computer Programming, Part 3: Searching and Sorting'' for more
+information.
+
+The weakest aspect of this function is that there can be at most one
+hashing table used throught the whole program. The table is allocated
+in local memory out of control of the programmer. As an extension the
+GNU C library provides an additional set of functions with an reentrant
+interface which provide a similar interface but which allow to keep
+arbitrary many hashing tables.
+
+It is possible to use more than one hashing table in the program run if
+the former table is first destroyed by a call to @code{hdestroy}.
+
+The function returns a non-zero value if successful. If it return zero
+something went wrong. This could either mean there is already a hashing
+table in use or the program runs out of memory.
+@end deftypefun
+
+@comment search.h
+@comment SVID
+@deftypefun void hdestroy (void)
+The @code{hdestroy} function can be used to free all the resources
+allocated in a previous call of @code{hcreate}. After a call to this
+function it is again possible to call @code{hcreate} and allocate a new
+table with possibly different size.
+
+It is important to remember that the elements contained in the hashing
+table at the time @code{hdestroy} is called are @emph{not} freed by this
+function. It is the responsibility of the program code to free those
+strings (if necessary at all). Freeing all the element memory iss not
+possible without extra, separately kept information since there is no
+function to iterate through all available elements in the hashing table.
+If it is really necessary to free a table and all elements the
+programmer has to keep a list of all table elements and before calling
+@code{hdestroy} s/he has to free all element's data using this list.
+This is a very unpleasent mechanism and it also shows that this kind of
+hashing tables is mainly meant for tables which are created once and
+used until the end of the program run.
+@end deftypefun
+
+Entries of the hashing table and keys for the search are defined using
+this type:
+
+@deftp {Data type} {struct ENTRY}
+Both elements of this structure are pointers to zero-terminated strings.
+This is a limiting restriction of the functionality of the
+@code{hsearch} functions. They can only be used for data sets which use
+the NUL character always and solely to terminate the records. It is not
+possible to handle general binary data.
+
+@table @code
+@item char *key
+Pointer to a zero-terminated string of characters describing the key for
+the search or the element in the hashing table.
+@item char *data
+Pointer to a zero-terminated string of characters describing the data.
+If the functions will be called only for searching an existing entry
+this element might stay undefined since it is not used.
+@end table
+@end deftp
+
+@comment search.h
+@comment SVID
+@deftypefun {ENTRY *} hsearch (ENTRY @var{item}, ACTION @var{action})
+To search in a hashing table created using @code{hcreate} the
+@code{hsearch} function must be used. This function can perform simple
+search for an element (if @var{action} has the @code{FIND}) or it can
+alternatively insert the key element into the hashing table, possibly
+replacing a previous value (if @var{action} is @code{ENTER}).
+
+The key is denoted by a pointer to an object of type @code{ENTRY}. For
+locating the corresponding position in the hashing table only the
+@code{key} element of the structure is used.
+
+The return value depends on the @var{action} parameter value. If it is
+@code{FIND} the value is a pointer to the matching element in the
+hashing table or @code{NULL} if no matching element exists. If
+@var{action} is @code{ENTER} the return value is only @code{NULL} if the
+programs runs out of memory while adding the new element to the table.
+Otherwise the return value is a pointer to the element in the hashing
+table which contains newly added element based on the data in @var{key}.
+@end deftypefun
+
+As mentioned before the hashing table used by the functions described so
+far is global and there can be at any time at most one hashing table in
+the program. A solution is to use the following functions which are a
+GNU extension. All have in common that they operate on a hashing table
+which is described by the content of an object of the type @code{struct
+hsearch_data}. This type should be treated as opaque, none of its
+members should be changed directly.
+
+@comment search.h
+@comment GNU
+@deftypefun int hcreate_r (size_t @var{nel}, struct hsearch_data *@var{htab})
+The @code{hcreate_r} function intializes the object pointed to by
+@var{htab} to contain a hashing table with at least @var{nel} elements.
+So this function is equivalent to the @code{hcreate} function except
+that the initialized data structure is controlled by the user.
+
+This allows to have more than once hashing table at one time. The
+memory necessary for the @code{struct hsearch_data} object can be
+allocated dynamically.
+
+The return value is non-zero if the operation were successful. if the
+return value is zero something went wrong which probably means the
+programs runs out of memory.
+@end deftypefun
+
+@comment search.h
+@comment GNU
+@deftypefun void hdestroy_r (struct hsearch_data *@var{htab})
+The @code{hdestroy_r} function frees all resources allocated by the
+@code{hcreate_r} function for this very same object @var{htab}. As for
+@code{hdestroy} it is the programs responsibility to free the strings
+for the elements of the table.
+@end deftypefun
+
+@comment search.h
+@comment GNU
+@deftypefun int hsearch_r (ENTRY @var{item}, ACTION @var{action}, ENTRY **@var{retval}, struct hsearch_data *@var{htab})
+The @code{hsearch_r} function is equivalent to @code{hsearch}. The
+meaning of the first two arguments is identical. But instead of
+operating on a single global hashing table the functio works on the
+table described by the object pointed to by @var{htab} (which is
+initialized by a call to @code{hcreate_r}).
+
+Another difference to @code{hcreate} is that the pointer to the found
+entry in the table is not the return value of the functions. It is
+returned by storing it in a pointer variables pointed to by the
+@var{retval} parameter. The return value of the function is an integer
+value indicating success if it is non-zero and failure if it is zero.
+In the later case the global variable @var{errno} signals the reason for
+the failure.

+
+@node Tree Search Function
+@section The @code{tsearch} function.
+
+Another common form to organize data for efficient search is to use
+trees. The @code{tsearch} function family provides a nice interface to
+functions to organize possibly large amounts of data by providing a mean
+access time proportional to the logarithm of the number of elements.
+The GNU C library implementation even guarantees that this bound is
+never exceeded even for input data which cause problems for simple
+binary tree implementations.
+
+The functions desribed in the chapter are all described in the @w{System
+V} and X/Open specifications and are therefore quite portable.
+
+In contrast to the @code{hsearch} functions the @code{tsearch} functions
+can be used with arbitrary data and not only zero-terminated strings.
+
+The @code{tsearch} functions have the advantage that no function to
+initialize data structures is necessary. A simple pointer of type
+@code{void *} initialized to @code{NULL} is a valid tree and can be
+extended or searched.
+
+@comment search.h
+@comment SVID
+@deftypefun {void *} tsearch (const void *@var{key}, void **@var{rootp}, comparison_fn_t @var{compar})
+The @code{tsearch} function searches in the tree pointed to by
+@code{*@var{rootp}} for an element matching @var{key}. The function
+pointed to by @var{compar} is used to determine wether two elements
+match. @xref{Comparison Functions} for a specification of the functions
+which can be used for the @var{compar} parameter.
+
+If the tree does not contain a matching entry the @var{key} value will
+be added to the tree. @code{tsearch} does not make a copy of the object
+pointed to by @var{key} (how could it since the size is unknown).
+Instead it adds a reference to this object which means the object must
+be available as long as the tree data structure is used.
+
+The tree is represented by a pointer to a pointer since it is sometimes
+necessary to change the root node of the tree. So it must not be
+assumed that the variable pointed to by @var{rootp} has the same value
+after the call. This also shows that it is not safe to call the
+@code{tsearch} function more than once at the same time using the same
+tree. It is no problem to run it more than once at a time on different
+trees.
+
+The return value is a pointer to the matching element in the tree. If a
+new element was created the pointer points to the new data (which is in
+fact @var{key}). If an entry had to be created and the program ran out
+of space @code{NULL} is returned.

+@deftypefun {void *} tfind (const void *@var{key}, void *const *@var{rootp}, comparison_fn_t @var{compar})
+The @code{tfind} function is similar to the @code{tsearch} function. It
+locates an element matching the one pointed to by @var{key} and returns
+a pointer to this element. But if no matching element is available no
+new element is entered (note that the @var{rootp} parameter points to a
+constant pointer). Instead the function returns @code{NULL}.
+@end deftypefun
+
+Another advantage of the @code{tsearch} function in contrast to the
+@code{hsearch} functions is that there is an easy way to remove
+elements.
+
+@comment search.h
+@comment SVID
+@deftypefun {void *} tdelete (const void *@var{key}, void **@var{rootp}, comparison_fn_t @var{compar})
+To remove a specific element matching @var{key} from the tree
+@code{tdelete} can be used. It locates the matching element using the
+same method as @code{tfind}. The corresponding element is then removed
+and the data if this tree node is returned by the function. If there is
+no matching entry in the tree nothing can be deleted and the function
+returns @code{NULL}.
+@end deftypefun
+
+@comment search.h
+@comment GNU
+@deftypefun void tdestroy (void *@var{vroot}, __free_fn_t @var{freefct})
+If the complete search tree has to be removed one can use
+@code{tdestroy}. It frees all resources allocated by the @code{tsearch}
+function to generate the tree pointed to by @var{vroot}.
+
+For the data in each tree node the function @var{freefct} is called.
+The pointer to the data is passed as the argument to the function. If
+no such work is necessary @var{freefct} must point to a function doing
+nothing. It is called in any case.
+
+This function is a GNU extension and not covered by the @w{System V} or
+X/Open specifications.
+@end deftypefun
+
+In addition to the function to create and destroy the tree data
+structure there is another function which allows to apply a function on
+all elements of the tree. The function must have this type:
+
+@smallexample
+int __action_fn_t (const void *nodep, VISIT value, int level);
+@end smallexample
+
+The @var{nodep} is the data value of the current node (nce given as the
+@var{key} argument to @code{tsearch}). @var{level} is a numeric value
+which corresponds to the depth of the current node in the tree. The
+root node has the depth @math{0} and its children have a depth of
+@math{1} and so on. The @code{VISIT} type is an enumeration type.
+
+@deftp {Data Type} VISIT
+The @code{VISIT} value indicates the status of the current node in the
+tree and how the function is called. The status of a node is either
+`leaf' or `internal node'. For each leaf node the function is called
+exactly once, for each internal node it is called three times: before
+the first child is processed, after the first child is processed and
+after both childs are processed. This makes it possible to handle all
+three methods of tree traversal (or even a combination of them).
+
+@table @code
+@item preorder
+The current node is an internal node and the function is called before
+the first child was processed.
+@item endorder
+The current node is an internal node and the function is called after
+the first child was processed.
+@item postorder
+The current node is an internal node and the function is called after
+the second child was processed.
+@item leaf
+The current node is a leaf.
+@end table
+@end deftp
+
+@comment search.h
+@comment SVID
+@deftypefun void twalk (const void *@var{root}, __action_fn_t @var{action})
+For each node in the tree with a node pointed to by @var{root} the
+@code{twalk} function calls the function provided by the parameter
+@var{action}. For leaf nodes the function is called exactly once with
+@var{value} set to @code{leaf}. For internal nodes the function is
+called three times, setting the @var{value} parameter or @var{action} to
+the appropriate value. The @var{level} argument for the @var{action}
+function is computed while descending the tree with increasing the value
+by one for the escend to a child, starting with the value @math{0} for
+the root node.
+
+Since the functions used for the @var{action} parameter to @code{twalk}
+must not modify the tree data it is safe to run @code{twalk} is more
+than one thread at the same time working on the same tree. It is also
+safe to call @code{tfind} in parallel. Functions which modify the tree
+must not be used. Otherwise the behaviour is undefined.
