+@deftypefn Replacement void* alloca (size_t)
+
+This function allocates memory which will be automatically reclaimed
+after the procedure exits. The @libib{} implementation does not free
+the memory immediately but will do so eventually during subsequent
+calls to this function. Memory is allocated using @code{xmalloc} under
+normal circumstances.
+
+The header file @file{alloca-conf.h} can be used in conjunction with the
+GNU Autoconf test @code{AC_FUNC_ALLOCA} to test for and properly make
+available this function. The @code{AC_FUNC_ALLOCA} test requires that
+client code use a block of preprocessor code to be safe (see the Autoconf
+manual for more); this header incorporates that logic and more, including
+the possibility of a GCC builtin function.

+Compares the first @var{count} bytes of two areas of memory. Returns
+zero if they are the same, non-zero otherwise. Returns zero if

-
- Compare two memory regions and return zero if they are identical,

-NOTES
-
- No guarantee is made about the non-zero returned value. In

+@center Version 2.1, February 1999
+
+@display
+Copyright @copyright{} 1991, 1999 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 Lesser GPL. It also counts
+as the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+@end display
+
+@appendixsubsec 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 Lesser General Public License, applies to some
+specially designated software---typically libraries---of the Free
+Software Foundation and other authors who decide to use it. You can use
+it too, but we suggest you first think carefully about whether this
+license or the ordinary General Public License is the better strategy to
+use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+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 and use pieces of it
+in new free programs; and that you are informed that you can do these
+things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+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 other code 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.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the @dfn{Lesser} General Public License because it
+does @emph{Less} to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ 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, whereas the latter must
+be combined with the library in order to run.

+@end ifinfo
+
+@enumerate 0
+@item
+This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this
+Lesser 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.
+
+@item
+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.
+
+@item
+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:
+
+@enumerate a
+@item
+The modified work must itself be a software library.
+
+@item
+You must cause the files modified to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause the whole of the work to be licensed at no
+charge to all third parties under the terms of this License.
+
+@item
+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.)
+@end enumerate
+
+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.
+
+@item
+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.
+
+@item
+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.
+
+@item
+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.
+
+@item
+As an exception to the Sections above, you may also combine 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:
+
+@enumerate a
+@item
+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.)
+
+@item
+Use a suitable shared library mechanism for linking with the Library. A
+suitable mechanism is one that (1) uses at run time a copy of the
+library already present on the user's computer system, rather than
+copying library functions into the executable, and (2) will operate
+properly with a modified version of the library, if the user installs
+one, as long as the modified version is interface-compatible with the
+version that the work was made with.
+
+@item
+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.
+
+@item
+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.
+
+@item
+Verify that the user has already received a copy of these
+materials or that you have already sent this user a copy.
+@end enumerate
+
+ 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 materials to be 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.
+
+@item
+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:
+
+@enumerate a
+@item
+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.
+
+@item
+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.
+@end enumerate
+
+@item
+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.
+
+@item
+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.
+
+@item
+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 with
+this License.
+
+@item
+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

+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,

+The Free Software Foundation may publish revised and/or new
+versions of the Lesser 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.

+@appendixsubsec 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.

+@c each entry tell you which file and where in that file). DO NOT EDIT!
+@c Edit the *.c files, configure with --enable-maintainer-mode,
+@c and let gather-docs build you a new copy.
+
+@c alloca.c:26
+@deftypefn Replacement void* alloca (size_t)
+
+This function allocates memory which will be automatically reclaimed
+after the procedure exits. The @libib{} implementation does not free
+the memory immediately but will do so eventually during subsequent
+calls to this function. Memory is allocated using @code{xmalloc} under
+normal circumstances.
+
+The header file @file{alloca-conf.h} can be used in conjunction with the
+GNU Autoconf test @code{AC_FUNC_ALLOCA} to test for and properly make
+available this function. The @code{AC_FUNC_ALLOCA} test requires that
+client code use a block of preprocessor code to be safe (see the Autoconf
+manual for more); this header incorporates that logic and more, including
+the possibility of a GCC builtin function.
+
+@end deftypefn
+
+@c atexit.c:6
+@deftypefn Supplemental int atexit (void (*@var{f})())
+
+Causes function @var{f} to be called at exit. Returns 0.
+
+@end deftypefn
+
+@c basename.c:6
+@deftypefn Supplemental char* basename (const char *@var{name})
+
+Returns a pointer to the last component of pathname @var{name}.
+Behavior is undefined if the pathname ends in a directory separator.
+
+@end deftypefn
+
+@c bcmp.c:6
+@deftypefn Supplemental int bcmp (char *@var{x}, char *@var{y}, int @var{count})
+
+Compares the first @var{count} bytes of two areas of memory. Returns
+zero if they are the same, non-zero otherwise. Returns zero if
+@var{count} is zero. A non-zero result only indicates a difference,
+it does not indicate any sorting order (say, by having a positive
+result mean @var{x} sorts before @var{y}).
+
+@end deftypefn
+
+@c bcopy.c:3
+@deftypefn Supplemental void bcopy (char *@var{in}, char *@var{out}, int @var{length})
+
+Copies @var{length} bytes from memory region @var{in} to region
+@var{out}. The use of @code{bcopy} is deprecated in new programs.
+
+@end deftypefn
+
+@c bsearch.c:33
+@deftypefn Supplemental void* bsearch (const void *@var{key}, const void *@var{base}, size_t @var{nmemb}, size_t @var{size}, int (*@var{compar})(const void *, const void *))
+
+Performs a search over an array of @var{nmemb} elements pointed to by
+@var{base} for a member that matches the object pointed to by @var{key}.
+The size of each member is specified by @var{size}. The array contents
+should be sorted in ascending order according to the @var{compar}
+comparison function. This routine should take two arguments pointing to
+the @var{key} and to an array member, in that order, and should return an
+integer less than, equal to, or greater than zero if the @var{key} object
+is respecitively less than, matching, or greater than the array member.
+
+@end deftypefn
+
+@c bzero.c:6
+@deftypefn Supplemental void bzero (char *@var{mem}, int @var{count})
+
+Zeros @var{count} bytes starting at @var{mem}. Use if this function
+is deprecated in favor of @code{memset}.
+
+@end deftypefn
+
+@c calloc.c:6
+@deftypefn Supplemental void* calloc (size_t @var{nelem}, size_t @var{elsize})
+
+Uses @code{malloc} to allocate storage for @var{nelem} objects of
+@var{elsize} bytes each, then zeros the memory.
+
+@end deftypefn
+
+@c clock.c:27
+@deftypefn Supplemental long clock ()
+
+Returns an approximation of the CPU time used by the process as a
+@code{clock_t}; divide this number by @samp{CLOCKS_PER_SEC} to get the
+number of seconds used.
+
+@end deftypefn
+
+@c strerror.c:566
+@deftypefn Replacement int errno_max (void)
+
+Returns the maximum @code{errno} value for which a corresponding
+symbolic name or message is available. Note that in the case where we
+use the @code{sys_errlist} supplied by the system, it is possible for
+there to be more symbolic names than messages, or vice versa. In
+fact, the manual page for @code{perror(3C)} explicitly warns that one
+should check the size of the table (@code{sys_nerr}) before indexing
+it, since new error codes may be added to the system before they are
+added to the table. Thus @code{sys_nerr} might be smaller than value
+implied by the largest @code{errno} value defined in @file{errno.h}.
+
+We return the maximum value that can be used to obtain a meaningful
+symbolic name or message.
+
+@end deftypefn
+
+@c getcwd.c:6
+@deftypefn Supplemental char* getcwd (char *@var{pathname}, @var{len})
+
+Copy the absolute pathname for the current working directory into
+@var{pathname}, which is assumed to point to a buffer of at least
+@var{len} bytes, and return a pointer to the buffer. If the current
+directory's path doesn't fit in @var{len} characters, the result is
+NULL and @var{errno} is set. If @var{pathname} is a null pointer,
+@code{getcwd} will obtain @var{len} bytes of space using
+@code{malloc}.
+
+@end deftypefn
+
+@c getpagesize.c:5
+@deftypefn Supplemental int getpagesize ()
+
+Returns the number of bytes in a page of memory. This is the
+granularity of many of the system memory management routines. No
+guarantee is made as to whether or not it is the same as the basic
+memory management hardware page size.
+
+@end deftypefn
+
+@c getpwd.c:5
+@deftypefn Supplemental char* getpwd ()
+
+Returns the current working directory. This implementation caches the
+result on the assumption that the process will not call @code{chdir}
+between calls to @code{getpwd}.
+
+@end deftypefn
+
+@c index.c:5
+@deftypefn Supplemental char* index (char *@var{s}, int @var{c})
+
+Returns a pointer to the first occurance of the character @var{c} in
+the string @var{s}, or NULL if not found. The use of @code{index} is
+deprecated in new programs in favor of @code{strchr}.
+
+@end deftypefn
+
+@c memchr.c:3
+@deftypefn Supplemental void* memchr (const void *@var{s}, int @var{c}, size_t @var{n})
+
+This function searches memory starting at @code{*}@var{src} for the
+character @var{c}. The search only ends with the first occurrence of
+@var{c}, or after @var{length} characters; in particular, a null
+character does not terminate the search. If the character @var{c} is
+found within @var{length} characters of @code{*}@var{src}, a pointer
+to the character is returned. If @var{c} is not found, then NULL is
+returned.
+
+@end deftypefn
+
+@c memcmp.c:6
+@deftypefn Supplemental int memcmp (const void *@var{x}, const void *@var{y}, size_t @var{count})
+
+Compares the first @var{count} bytes of two areas of memory. Returns
+zero if they are the same, a value less than zero if @var{x} is
+lexically less than @var{y}, or a value greater than zero if @var{x}
+is lexically greater than @var{y}. Note that lexical order is determined
+as if comparing unsigned char arrays.
+
+@end deftypefn
+
+@c memcpy.c:6
+@deftypefn Supplemental void* memcpy (void *@var{out}, const void *@var{in}, size_t @var{length})
+
+Copies @var{length} bytes from memory region @var{in} to region
+@var{out}. Returns a pointer to @var{out}.
+
+@end deftypefn
+
+@c memmove.c:6
+@deftypefn Supplemental void* memmove (void *@var{from}, const void *@var{to}, size_t @var{count})
+
+Copies @var{count} bytes from memory area @var{from} to memory area
+@var{to}, returning a pointer to @var{to}.
+
+@end deftypefn
+
+@c memset.c:6
+@deftypefn Supplemental void* memset (void *@var{s}, int @var{c}, size_t @var{count})
+
+Sets the first @var{count} bytes of @var{s} to the constant byte
+@var{c}, returning a pointer to @var{s}.
+
+@end deftypefn
+
+@c putenv.c:21
+@deftypefn Supplemental int putenv (const char *@var{string})
+
+Uses @code{setenv} or @code{unsetenv} to put @var{string} into
+the environment or remove it. If @var{string} is of the form
+@samp{name=value} the string is added; if no `=' is present the
+name is unset/removed.
+
+@end deftypefn
+
+@c rename.c:6
+@deftypefn Supplemental int rename (const char *@var{old}, const char *@var{new})
+
+Renames a file from @var{old} to @var{new}. If @var{new} already
+exists, it is removed.
+
+@end deftypefn
+
+@c rindex.c:5
+@deftypefn Supplemental char* rindex (const char *@var{s}, int @var{c})
+
+Returns a pointer to the last occurance of the character @var{c} in
+the string @var{s}, or NULL if not found. The use of @code{rindex} is
+deprecated in new programs in favor of @code{strrchr}.
+
+@end deftypefn
+
+@c setenv.c:22
+@deftypefn Supplemental int setenv (const char *@var{name}, const char *@var{value}, int @var{overwrite})
+@deftypefnx Supplemental void unsetenv (const char *@var{name})
+
+@code{setenv} adds @var{name} to the environment with value
+@var{value}. If the name was already present in the environment,
+the new value will be stored only if @var{overwrite} is non-zero.
+The companion @code{unsetenv} function removes @var{name} from the
+environment. This implementation is not safe for multithreaded code.
+
+@end deftypefn
+
+@c sigsetmask.c:8
+@deftypefn Supplemental int sigsetmask (int @var{set})
+
+Sets the signal mask to the one provided in @var{set} and returns
+the old mask (which, for libiberty's implementation, will always
+be the value @code{1}).
+
+@end deftypefn
+
+@c strcasecmp.c:15
+@deftypefn Supplemental int strcasecmp (const char *@var{s1}, const char *@var{s2})
+
+A case-insensitive @code{strcmp}.
+
+@end deftypefn
+
+@c strchr.c:6
+@deftypefn Supplemental char* strchr (const char *@var{s}, int @var{c})
+
+Returns a pointer to the first occurance of the character @var{c} in
+the string @var{s}, or NULL if not found. If @var{c} is itself the
+null character, the results are undefined.
+
+@end deftypefn
+
+@c strdup.c:3
+@deftypefn Supplemental char* strdup (const char *@var{s})
+
+Returns a pointer to a copy of @var{s} in memory obtained from
+@code{malloc}, or NULL if insufficient memory was available.
+
+@end deftypefn
+
+@c strerror.c:670
+@deftypefn Replacement const char* strerrno (int @var{errnum})
+
+Given an error number returned from a system call (typically returned
+in @code{errno}), returns a pointer to a string containing the
+symbolic name of that error number, as found in @file{errno.h}.
+
+If the supplied error number is within the valid range of indices for
+symbolic names, but no name is available for the particular error
+number, then returns the string @samp{"Error NUM"}, where NUM is the
+error number.
+
+If the supplied error number is not within the range of valid
+indices, then returns NULL.
+
+The contents of the location pointed to are only guaranteed to be
+valid until the next call to strerrno.
+
+@end deftypefn
+
+@c strerror.c:602
+@deftypefn Replacement char* strerror (int @var{errnoval})
+
+Maps an @code{errno} number to an error message string, the contents
+of which are implementation defined. On systems which have the
+external variables @code{sys_nerr} and @code{sys_errlist}, these
+strings will be the same as the ones used by @code{perror}.
+
+If the supplied error number is within the valid range of indices for
+the @code{sys_errlist}, but no message is available for the particular
+error number, then returns the string @samp{"Error NUM"}, where NUM is
+the error number.
+
+If the supplied error number is not a valid index into
+@code{sys_errlist}, returns NULL.
+
+The returned string is only guaranteed to be valid only until the
+next call to @code{strerror}.
+
+@end deftypefn
+
+@c strncasecmp.c:15
+@deftypefn Supplemental int strncasecmp (const char *@var{s1}, const char *@var{s2})
+
+A case-insensitive @code{strncmp}.
+
+@end deftypefn
+
+@c strncmp.c:6
+@deftypefn Supplemental int strncmp (const char *@var{s1}, const char *@var{s2}, size_t @var{n})
+
+Compares the first @var{n} bytes of two strings, returning a value as
+@code{strcmp}.
+
+@end deftypefn
+
+@c strrchr.c:6
+@deftypefn Supplemental char* strrchr (const char *@var{s}, int @var{c})
+
+Returns a pointer to the last occurance of the character @var{c} in
+the string @var{s}, or NULL if not found. If @var{c} is itself the
+null character, the results are undefined.
+
+@end deftypefn
+
+@c strstr.c:6
+@deftypefn Supplemental char* strstr (const char *@var{string}, const char *@var{sub})
+
+This function searches for the substring @var{sub} in the string
+@var{string}, not including the terminating NUL characters. A pointer
+to the first occurance of @var{sub} is returned, or NULL if the
+substring is absent. If @var{sub} points to a string with zero
+length, the function returns @var{string}.
+
+@end deftypefn
+
+@c strtod.c:27
+@deftypefn Supplemental double strtod (const char *@var{string}, char **@var{endptr})
+
+This ANSI C function converts the initial portion of @var{string} to a
+@code{double}. If @var{endptr} is not NULL, a pointer to the
+character after the last character used in the conversion is stored in
+the location referenced by @var{endptr}. If no conversion is
+performed, zero is returned and the value of @var{string} is stored in
+the location referenced by @var{endptr}.
+
+@end deftypefn
+
+@c strerror.c:730
+@deftypefn Replacement int strtoerrno (const char *@var{name})
+
+Given the symbolic name of a error number (e.g., @code{EACCESS}), map it
+to an errno value. If no translation is found, returns 0.
+
+@end deftypefn
+
+@c strtol.c:33
+@deftypefn Supplemental {long int} strtol (const char *@var{string}, char **@var{endptr}, int @var{base})
+
+The @code{strtol} function converts the string in @var{string} to a
+long integer value according to the given @var{base}, which must be
+between 2 and 36 inclusive, or be the special value 0. If @var{base}
+is 0, @code{strtol} will look for the prefixes @code{0} and @code{0x}
+to indicate bases 8 and 16, respectively, else default to base 10.
+When the base is 16 (either explicitly or implicitly), a prefix of
+@code{0x} is allowed. The handling of endptr is as that of
+@code{strtod} above.
+
+@end deftypefn
+
+@c tmpnam.c:3
+@deftypefn Supplemental char* tmpnam (char *@var{s})
+
+This function attempts to create a name for a temporary file, which
+will be a valid file name yet not exist when @code{tmpnam} checks for
+it. @var{s} must point to a buffer of at least @code{L_tmpnam} bytes,
+or be NULL. Use of this function creates a security risk, and it must
+not be used in new projects. Use @code{mkstemp} instead.
+
+@end deftypefn
+
+@c vfork.c:6
+@deftypefn Supplemental int vfork ()
+
+Emulates @code{vfork} by calling @code{fork} and returning its value.
+
+@end deftypefn
+
+@c vprintf.c:3
+@deftypefn Supplemental int vprintf (const char *@var{format}, va_list @var{ap})
+@deftypefnx Supplemental int vfprintf (FILE *@var{stream}, const char *@var{format}, va_list @var{ap})
+@deftypefnx Supplemental int vsprintf (char *@var{str}, const char *@var{format}, va_list @var{ap})
+
+These functions are the same as @code{printf}, @code{fprintf}, and
+@code{sprintf}, respectively, except that they are called with a
+@code{va_list} instead of a variable number of arguments. Note that
+they do not call @code{va_end}; this is the application's
+responsibility. In @libib{} they are implemented in terms of the
+nonstandard but common function @code{_doprnt}.
+
+@end deftypefn
+
+@c waitpid.c:3
+@deftypefn Supplemental int waitpid (int @var{pid}, int *@var{status}, int)
+
+This is a wrapper around the @code{wait} function. Any ``special''
+values of @var{pid} depend on your implementation of @code{wait}, as
+does the return value. The third argument is unused in @libib{}.
+
+@end deftypefn
+
+@c xatexit.c:11
+@deftypefun int xatexit (void (*@var{fn}) (void))
+
+Behaves as the standard @code{atexit} function, but with no limit on
+the number of registered funtions. Returns 0 on success, or -1 on
+failure. If you use @code{xatexit} to register functions, you must use
+@code{xexit} to terminate your program.
+
+@end deftypefun
+
+@c xmalloc.c:37
+@deftypefn Replacement void* xcalloc (size_t, size_t)
+
+Allocate memory without fail, and set it to zero. This routine functions
+like @code{calloc}, but will behave the same as @code{xmalloc} if memory
+cannot be found.
+
+@end deftypefn
+
+@c xexit.c:22
+@deftypefn Replacement void xexit (int @var{code})
+
+Terminates the program. If any functions have been registered with
+the @code{xatexit} rpelacement function, they will be called first.
+Termination is handled via the system's normal @code{exit} call.
+
+@end deftypefn
+
+@c xmalloc.c:22
+@deftypefn Replacement void* xmalloc (size_t)
+
+Allocate memory without fail. If @code{malloc} fails, this will print
+a message to stderr (using the name set by @code{xmalloc_set_program_name},
+if any) and then call @code{xexit}. Note that it is therefore safe for
+a program to contain @code{#define malloc xmalloc} in its source.
+
+@end deftypefn
+
+@c xmalloc.c:52
+@deftypefn Replacement void xmalloc_failed (size_t)
+
+This function is not meant to be called by client code, and is listed
+here for completeness only. If any of the allocation routines fail, this
+function will be called to print an error message and terminate execution.
+
+@end deftypefn
+
+@c xmalloc.c:45
+@deftypefn Replacement void xmalloc_set_program_name (const char *@var{name})
+
+You can use this to set the name of the program used by
+@code{xmalloc_failed} when printing a failure message.
+
+@end deftypefn
+
+@c xmemdup.c:7
+@deftypefn Replacement void* xmemdup (void *@var{input}, size_t @var{copy_size}, size_t @var{alloc_size})
+
+Duplicates a region of memory without fail. First, @var{alloc_size} bytes
+are allocated, then @var{copy_size} bytes from @var{input} are copied into
+it, and the new memory is returned. If fewer bytes are copied than were
+allocated, the remaining memory is zeroed.
+
+@end deftypefn
+
+@c xmalloc.c:31
+@deftypefn Replacement void* xrealloc (void*, size_t)
+Reallocate memory without fail. This routine functions like @code{realloc},
+but will behave the same as @code{xmalloc} if memory cannot be found.
+
+@end deftypefn
+
+@c xstrdup.c:7
+@deftypefn Replacement char* xstrdup (const char *@var{s})
+
+Duplicates a character string without fail, using @code{xmalloc} to
+obtain memory.
+
+@end deftypefn
+
+@c xstrerror.c:7
+@deftypefn Replacement char* xstrerror (int @var{errnum})
+
+Behaves exactly like the standard @code{strerror} function, but
+will never return a NULL pointer.

+@cindex libiberty usage
+@cindex how to use
+
+@c THIS SECTION IS CRAP AND NEEDS REWRITING BADLY.
+
+To date, @libib{} is generally not installed on its own. It has evolved
+over years but does not have its own version number nor release schedule.
+
+Possibly the easiest way to use @libib{} in your projects is to drop the
+@libib{} code into your project's sources, and to build the library along
+with your own sources; the library would then be linked in at the end. This
+prevents any possible version mismatches with other copies of libiberty
+elsewhere on the system.
+
+Passing @option{--enable-install-libiberty} to the @command{configure}
+script when building @libib{} causes the header files and archive library
+to be installed when @samp{make install} is run. This option also takes
+an (optional) argument to specify the installation location, in the same
+manner as @option{--prefix}.
+
+For your own projects, an approach which offers stability and flexibility
+is to include @libib{} with your code, but allow the end user to optionally
+choose to use a previously-installed version instead. In this way the
+user may choose (for example) to install @libib{} as part of GCC, and use
+that version for all software built with that compiler. (This approach
+has proven useful with software using the GNU @code{readline} library.)
+
+Making use of @libib{} code usually requires that you include one or more
+header files from the @libib{} distribution. (They will be named as
+necessary in the function descriptions.) At link time, you will need to
+add @option{-liberty} to your link command invocation.
+
+
+@node Overview,Functions,Using,Top
+@chapter Overview
+
+Functions contained in @libib{} can be divided into three general categories.
+
+
+@menu
+* Supplemental Functions:: Providing functions which don't exist
+ on older operating systems.
+
+* Replacement Functions:: These functions are sometimes buggy or
+ unpredictable on some operating systems.
+
+* Extensions:: Functions which provide useful extensions
+ or safety wrappers around existing code.
+@end menu
+
+@node Supplemental Functions,Replacement Functions,,Overview
+@section Supplemental Functions
+@cindex supplemental functions
+@cindex functions, supplemental
+@cindex functions, missing
+
+Certain operating systems do not provide functions which have since
+become standardized, or at least common. For example, the Single
+Unix Specification Version 2 requires that the @code{basename}
+function be provided, but an OS which predates that specification
+might not have this function. This should not prevent well-written
+code from running on such a system.
+
+Similarly, some functions exist only among a particular ``flavor''
+or ``family'' of operating systems. As an example, the @code{bzero}
+function is often not present on systems outside the BSD-derived
+family of systems.
+
+Many such functions are provided in @libib{}. They are quickly
+listed here with little description, as systems which lack them
+become less and less common. Each function @var{foo} is implemented
+in @file{foo.c} but not declared in any @libib{} header file; more
+comments and caveats for each function's implementation are often
+available in the source file. Generally, the function can simply
+be declared as @code{extern}.
+
+
+
+@node Replacement Functions,Extensions,Supplemental Functions,Overview
+@section Replacement Functions
+@cindex replacement functions
+@cindex functions, replacement
+
+Some functions have extremely limited implementations on different
+platforms. Other functions are tedious to use correctly; for example,
+proper use of @code{malloc} calls for the return value to be checked and
+appropriate action taken if memory has been exhausted. A group of
+``replacement functions'' is available in @libib{} to address these issues
+for some of the most commonly used subroutines.
+
+All of these functions are declared in the @file{libiberty.h} header
+file. Many of the implementations will use preprocessor macros set by
+GNU Autoconf, if you decide to make use of that program. Some of these
+functions may call one another.
+
+
+@menu
+* Memory Allocation:: Testing and handling failed memory
+ requests automatically.
+* Exit Handlers:: Calling routines on program exit.
+* Error Reporting:: Mapping errno and signal numbers to
+ more useful string formats.
+@end menu
+
+@node Memory Allocation
+@subsection Memory Allocation
+@cindex memory allocation
+
+The functions beginning with the letter `x' are wrappers around
+standard functions; the functions provided by the system environment
+are called and their results checked before the results are passed back
+to client code. If the standard functions fail, these wrappers will
+terminate the program. Thus, these versions can be used with impunity.
+
+
+@node Exit Handlers
+@subsection Exit Handlers
+@cindex exit handlers
+
+The existence and implementation of the @code{atexit} routine varies
+amongst the flavors of Unix. @libib{} provides an unvarying dependable
+implementation via @code{xatexit} and @code{xexit}.
+
+
+@node Error Reporting
+@subsection Error Reporting
+@cindex error reporting
+
+These are a set of routines to facilitate programming with the system
+@code{errno} interface. The @libib{} source file @file{strerror.c}
+contains a good deal of documentation for these functions.

+functions, which has proven generically useful in GNU programs, such as

+@cindex obstacks
+
+An @dfn{obstack} is a pool of memory containing a stack of objects. You
+can create any number of separate obstacks, and then allocate objects in
+specified obstacks. Within each obstack, the last object allocated must
+always be the first one freed, but distinct obstacks are independent of
+each other.
+
+Aside from this one constraint of order of freeing, obstacks are totally
+general: an obstack can contain any number of objects of any size. They
+are implemented with macros, so allocation is usually very fast as long as
+the objects are usually small. And the only space overhead per object is
+the padding needed to start each object on a suitable boundary.

+@comment GNU
+@deftp {Data Type} {struct obstack}
+An obstack is represented by a data structure of type @code{struct
+obstack}. This structure has a small fixed size; it records the status
+of the obstack and how to find the space in which objects are allocated.
+It does not contain any of the objects themselves. You should not try
+to access the contents of the structure directly; use only the functions
+described in this chapter.
+@end deftp
+
+You can declare variables of type @code{struct obstack} and use them as
+obstacks, or you can allocate obstacks dynamically like any other kind
+of object. Dynamic allocation of obstacks allows your program to have a
+variable number of different stacks. (You can even allocate an
+obstack structure in another obstack, but this is rarely useful.)
+
+All the functions that work with obstacks require you to specify which
+obstack to use. You do this with a pointer of type @code{struct obstack
+*}. In the following, we often say ``an obstack'' when strictly
+speaking the object at hand is such a pointer.
+
+The objects in the obstack are packed into large blocks called
+@dfn{chunks}. The @code{struct obstack} structure points to a chain of
+the chunks currently in use.
+
+The obstack library obtains a new chunk whenever you allocate an object
+that won't fit in the previous chunk. Since the obstack library manages
+chunks automatically, you don't need to pay much attention to them, but
+you do need to supply a function which the obstack library should use to
+get a chunk. Usually you supply a function which uses @code{malloc}
+directly or indirectly. You must also supply a function to free a chunk.
+These matters are described in the following section.
+
+@node Preparing for Obstacks

+@smallexample
+#include <obstack.h>
+@end smallexample
+
+@findex obstack_chunk_alloc
+@findex obstack_chunk_free
+Also, if the source file uses the macro @code{obstack_init}, it must
+declare or define two functions or macros that will be called by the
+obstack library. One, @code{obstack_chunk_alloc}, is used to allocate
+the chunks of memory into which objects are packed. The other,
+@code{obstack_chunk_free}, is used to return chunks when the objects in
+them are freed. These macros should appear before any use of obstacks
+in the source file.
+
+Usually these are defined to use @code{malloc} via the intermediary
+@code{xmalloc} (@pxref{Unconstrained Allocation, , , libc, The GNU C Library Reference Manual}). This is done with
+the following pair of macro definitions:
+
+@smallexample
+#define obstack_chunk_alloc xmalloc
+#define obstack_chunk_free free
+@end smallexample
+
+@noindent
+Though the memory you get using obstacks really comes from @code{malloc},
+using obstacks is faster because @code{malloc} is called less often, for
+larger blocks of memory. @xref{Obstack Chunks}, for full details.
+
+At run time, before the program can use a @code{struct obstack} object
+as an obstack, it must initialize the obstack by calling
+@code{obstack_init}.
+
+@comment obstack.h
+@comment GNU
+@deftypefun int obstack_init (struct obstack *@var{obstack-ptr})

+@node Allocation in an Obstack
+@section Allocation in an Obstack
+@cindex allocation (obstacks)
+
+The most direct way to allocate an object in an obstack is with
+@code{obstack_alloc}, which is invoked almost like @code{malloc}.
+
+@comment obstack.h
+@comment GNU
+@deftypefun {void *} obstack_alloc (struct obstack *@var{obstack-ptr}, int @var{size})
+This allocates an uninitialized block of @var{size} bytes in an obstack
+and returns its address. Here @var{obstack-ptr} specifies which obstack
+to allocate the block in; it is the address of the @code{struct obstack}
+object which represents the obstack. Each obstack function or macro
+requires you to specify an @var{obstack-ptr} as the first argument.
+
+This function calls the obstack's @code{obstack_chunk_alloc} function if
+it needs to allocate a new chunk of memory; it calls
+@code{obstack_alloc_failed_handler} if allocation of memory by
+@code{obstack_chunk_alloc} failed.
+@end deftypefun
+
+For example, here is a function that allocates a copy of a string @var{str}
+in a specific obstack, which is in the variable @code{string_obstack}:
+
+@smallexample
+struct obstack string_obstack;
+
+char *
+copystring (char *string)
+@{
+ size_t len = strlen (string) + 1;
+ char *s = (char *) obstack_alloc (&string_obstack, len);
+ memcpy (s, string, len);
+ return s;
+@}
+@end smallexample
+
+To allocate a block with specified contents, use the function
+@code{obstack_copy}, declared like this:
+
+@comment obstack.h
+@comment GNU
+@deftypefun {void *} obstack_copy (struct obstack *@var{obstack-ptr}, void *@var{address}, int @var{size})
+This allocates a block and initializes it by copying @var{size}
+bytes of data starting at @var{address}. It calls
+@code{obstack_alloc_failed_handler} if allocation of memory by
+@code{obstack_chunk_alloc} failed.
+@end deftypefun
+
+@comment obstack.h
+@comment GNU
+@deftypefun {void *} obstack_copy0 (struct obstack *@var{obstack-ptr}, void *@var{address}, int @var{size})
+Like @code{obstack_copy}, but appends an extra byte containing a null
+character. This extra byte is not counted in the argument @var{size}.
+@end deftypefun
+
+The @code{obstack_copy0} function is convenient for copying a sequence
+of characters into an obstack as a null-terminated string. Here is an
+example of its use:
+
+@smallexample
+char *
+obstack_savestring (char *addr, int size)
+@{
+ return obstack_copy0 (&myobstack, addr, size);
+@}
+@end smallexample
+
+@noindent
+Contrast this with the previous example of @code{savestring} using
+@code{malloc} (@pxref{Basic Allocation, , , libc, The GNU C Library Reference Manual}).
+
+@node Freeing Obstack Objects
+@section Freeing Objects in an Obstack
+@cindex freeing (obstacks)
+
+To free an object allocated in an obstack, use the function
+@code{obstack_free}. Since the obstack is a stack of objects, freeing
+one object automatically frees all other objects allocated more recently
+in the same obstack.
+
+@comment obstack.h
+@comment GNU
+@deftypefun void obstack_free (struct obstack *@var{obstack-ptr}, void *@var{object})
+If @var{object} is a null pointer, everything allocated in the obstack
+is freed. Otherwise, @var{object} must be the address of an object
+allocated in the obstack. Then @var{object} is freed, along with
+everything allocated in @var{obstack} since @var{object}.
+@end deftypefun
+
+Note that if @var{object} is a null pointer, the result is an
+uninitialized obstack. To free all memory in an obstack but leave it
+valid for further allocation, call @code{obstack_free} with the address
+of the first object allocated on the obstack:
+
+@smallexample
+obstack_free (obstack_ptr, first_object_allocated_ptr);
+@end smallexample
+
+Recall that the objects in an obstack are grouped into chunks. When all
+the objects in a chunk become free, the obstack library automatically
+frees the chunk (@pxref{Preparing for Obstacks}). Then other
+obstacks, or non-obstack allocation, can reuse the space of the chunk.
+
+@node Obstack Functions
+@section Obstack Functions and Macros
+@cindex macros
+
+The interfaces for using obstacks may be defined either as functions or
+as macros, depending on the compiler. The obstack facility works with
+all C compilers, including both @w{ISO C} and traditional C, but there are
+precautions you must take if you plan to use compilers other than GNU C.
+
+If you are using an old-fashioned @w{non-ISO C} compiler, all the obstack
+``functions'' are actually defined only as macros. You can call these
+macros like functions, but you cannot use them in any other way (for
+example, you cannot take their address).
+
+Calling the macros requires a special precaution: namely, the first
+operand (the obstack pointer) may not contain any side effects, because
+it may be computed more than once. For example, if you write this:
+
+@smallexample
+obstack_alloc (get_obstack (), 4);
+@end smallexample
+
+@noindent
+you will find that @code{get_obstack} may be called several times.
+If you use @code{*obstack_list_ptr++} as the obstack pointer argument,
+you will get very strange results since the incrementation may occur
+several times.
+
+In @w{ISO C}, each function has both a macro definition and a function
+definition. The function definition is used if you take the address of the
+function without calling it. An ordinary call uses the macro definition by
+default, but you can request the function definition instead by writing the
+function name in parentheses, as shown here:
+
+@smallexample
+char *x;
+void *(*funcp) ();
+/* @r{Use the macro}. */
+x = (char *) obstack_alloc (obptr, size);
+/* @r{Call the function}. */
+x = (char *) (obstack_alloc) (obptr, size);
+/* @r{Take the address of the function}. */
+funcp = obstack_alloc;
+@end smallexample
+
+@noindent
+This is the same situation that exists in @w{ISO C} for the standard library
+functions. @xref{Macro Definitions, , , libc, The GNU C Library Reference Manual}.
+
+@strong{Warning:} When you do use the macros, you must observe the
+precaution of avoiding side effects in the first operand, even in @w{ISO C}.
+
+If you use the GNU C compiler, this precaution is not necessary, because
+various language extensions in GNU C permit defining the macros so as to
+compute each argument only once.
+
+@node Growing Objects
+@section Growing Objects
+@cindex growing objects (in obstacks)
+@cindex changing the size of a block (obstacks)
+
+Because memory in obstack chunks is used sequentially, it is possible to
+build up an object step by step, adding one or more bytes at a time to the
+end of the object. With this technique, you do not need to know how much
+data you will put in the object until you come to the end of it. We call
+this the technique of @dfn{growing objects}. The special functions
+for adding data to the growing object are described in this section.
+
+You don't need to do anything special when you start to grow an object.
+Using one of the functions to add data to the object automatically
+starts it. However, it is necessary to say explicitly when the object is
+finished. This is done with the function @code{obstack_finish}.
+
+The actual address of the object thus built up is not known until the
+object is finished. Until then, it always remains possible that you will
+add so much data that the object must be copied into a new chunk.
+
+While the obstack is in use for a growing object, you cannot use it for
+ordinary allocation of another object. If you try to do so, the space
+already added to the growing object will become part of the other object.

+This function can return a null pointer under the same conditions as
+@code{obstack_alloc} (@pxref{Allocation in an Obstack}).
+@end deftypefun
+
+When you build an object by growing it, you will probably need to know
+afterward how long it became. You need not keep track of this as you grow
+the object, because you can find out the length from the obstack just
+before finishing the object with the function @code{obstack_object_size},
+declared as follows:
+
+@comment obstack.h
+@comment GNU
+@deftypefun int obstack_object_size (struct obstack *@var{obstack-ptr})
+This function returns the current size of the growing object, in bytes.
+Remember to call this function @emph{before} finishing the object.
+After it is finished, @code{obstack_object_size} will return zero.
+@end deftypefun
+
+If you have started growing an object and wish to cancel it, you should
+finish it and then free it, like this:
+
+@smallexample
+obstack_free (obstack_ptr, obstack_finish (obstack_ptr));
+@end smallexample
+
+@noindent
+This has no effect if no object was growing.
+
+@cindex shrinking objects
+You can use @code{obstack_blank} with a negative size argument to make
+the current object smaller. Just don't try to shrink it beyond zero
+length---there's no telling what will happen if you do that.
+
+@node Extra Fast Growing
+@section Extra Fast Growing Objects
+@cindex efficiency and obstacks
+
+The usual functions for growing objects incur overhead for checking
+whether there is room for the new growth in the current chunk. If you
+are frequently constructing objects in small steps of growth, this
+overhead can be significant.
+
+You can reduce the overhead by using special ``fast growth''
+functions that grow the object without checking. In order to have a
+robust program, you must do the checking yourself. If you do this checking
+in the simplest way each time you are about to add data to the object, you
+have not saved anything, because that is what the ordinary growth
+functions do. But if you can arrange to check less often, or check
+more efficiently, then you make the program faster.
+
+The function @code{obstack_room} returns the amount of room available
+in the current chunk. It is declared as follows:
+
+@comment obstack.h
+@comment GNU
+@deftypefun int obstack_room (struct obstack *@var{obstack-ptr})

+growing object (or to an object about to be started) in obstack
+@var{obstack} using the fast growth functions.

+
+When you check for space using @code{obstack_room} and there is not
+enough room for what you want to add, the fast growth functions
+are not safe. In this case, simply use the corresponding ordinary
+growth function instead. Very soon this will copy the object to a
+new chunk; then there will be lots of room available again.
+
+So, each time you use an ordinary growth function, check afterward for
+sufficient space using @code{obstack_room}. Once the object is copied
+to a new chunk, there will be plenty of space again, so the program will
+start using the fast growth functions again.

+@node Obstacks Data Alignment
+@section Alignment of Data in Obstacks
+@cindex alignment (in obstacks)
+
+Each obstack has an @dfn{alignment boundary}; each object allocated in
+the obstack automatically starts on an address that is a multiple of the
+specified boundary. By default, this boundary is 4 bytes.
+
+To access an obstack's alignment boundary, use the macro
+@code{obstack_alignment_mask}, whose function prototype looks like
+this:
+
+@comment obstack.h
+@comment GNU
+@deftypefn Macro int obstack_alignment_mask (struct obstack *@var{obstack-ptr})
+The value is a bit mask; a bit that is 1 indicates that the corresponding
+bit in the address of an object should be 0. The mask value should be one
+less than a power of 2; the effect is that all object addresses are
+multiples of that power of 2. The default value of the mask is 3, so that
+addresses are multiples of 4. A mask value of 0 means an object can start
+on any multiple of 1 (that is, no alignment is required).
+
+The expansion of the macro @code{obstack_alignment_mask} is an lvalue,
+so you can alter the mask by assignment. For example, this statement:
+
+@smallexample
+obstack_alignment_mask (obstack_ptr) = 0;
+@end smallexample
+
+@noindent
+has the effect of turning off alignment processing in the specified obstack.
+@end deftypefn
+
+Note that a change in alignment mask does not take effect until
+@emph{after} the next time an object is allocated or finished in the
+obstack. If you are not growing an object, you can make the new
+alignment mask take effect immediately by calling @code{obstack_finish}.
+This will finish a zero-length object and then do proper alignment for
+the next object.
+
+@node Obstack Chunks
+@section Obstack Chunks
+@cindex efficiency of chunks
+@cindex chunks
+
+Obstacks work by allocating space for themselves in large chunks, and
+then parceling out space in the chunks to satisfy your requests. Chunks
+are normally 4096 bytes long unless you specify a different chunk size.
+The chunk size includes 8 bytes of overhead that are not actually used
+for storing objects. Regardless of the specified size, longer chunks
+will be allocated when necessary for long objects.
+
+The obstack library allocates chunks by calling the function
+@code{obstack_chunk_alloc}, which you must define. When a chunk is no
+longer needed because you have freed all the objects in it, the obstack
+library frees the chunk by calling @code{obstack_chunk_free}, which you
+must also define.
+
+These two must be defined (as macros) or declared (as functions) in each
+source file that uses @code{obstack_init} (@pxref{Creating Obstacks}).
+Most often they are defined as macros like this:
+
+@smallexample
+#define obstack_chunk_alloc malloc
+#define obstack_chunk_free free
+@end smallexample
+
+Note that these are simple macros (no arguments). Macro definitions with
+arguments will not work! It is necessary that @code{obstack_chunk_alloc}
+or @code{obstack_chunk_free}, alone, expand into a function name if it is
+not itself a function name.
+
+If you allocate chunks with @code{malloc}, the chunk size should be a
+power of 2. The default chunk size, 4096, was chosen because it is long
+enough to satisfy many typical requests on the obstack yet short enough
+not to waste too much memory in the portion of the last chunk not yet used.
+
+@comment obstack.h
+@comment GNU
+@deftypefn Macro int obstack_chunk_size (struct obstack *@var{obstack-ptr})
+This returns the chunk size of the given obstack.
+@end deftypefn
+
+Since this macro expands to an lvalue, you can specify a new chunk size by
+assigning it a new value. Doing so does not affect the chunks already
+allocated, but will change the size of chunks allocated for that particular
+obstack in the future. It is unlikely to be useful to make the chunk size
+smaller, but making it larger might improve efficiency if you are
+allocating many objects whose size is comparable to the chunk size. Here
+is how to do so cleanly:
+
+@smallexample
