Library Maintenance
*******************
How to Install the GNU C Library
================================
Installation of the GNU C library is relatively simple.
You need the latest version of GNU `make'. Modifying the GNU C
Library to work with other `make' programs would be so hard that we
recommend you port GNU `make' instead. *Really.*
To configure the GNU C library for your system, run the shell script
`configure' with `sh'. Use an argument which is the conventional GNU
name for your system configuration--for example, `sparc-sun-sunos4.1',
for a Sun 4 running Sunos 4.1. *Note Installation:
(gcc.info)Installation, for a full description of standard GNU
configuration names. If you omit the configuration name, `configure'
will try to guess one for you by inspecting the system it is running
on. It may or may not be able to come up with a guess, and the its
guess might be wrong. `configure' will tell you the canonical name of
the chosen configuration before proceeding.
The GNU C Library currently supports configurations that match the
following patterns:
alpha-dec-osf1
i386-ANYTHING-bsd4.3
i386-ANYTHING-gnu
i386-ANYTHING-isc2.2
i386-ANYTHING-isc3.N
i386-ANYTHING-sco3.2
i386-ANYTHING-sco3.2v4
i386-ANYTHING-sysv
i386-ANYTHING-sysv4
i386-force_cpu386-none
i386-sequent-bsd
i960-nindy960-none
m68k-hp-bsd4.3
m68k-mvme135-none
m68k-mvme136-none
m68k-sony-newsos3
m68k-sony-newsos4
m68k-sun-sunos4.N
mips-dec-ultrix4.N
mips-sgi-irix4.N
sparc-sun-solaris2.N
sparc-sun-sunos4.N
While no other configurations are supported, there are handy aliases
for these few. (These aliases work in other GNU software as well.)

sun4-solaris2.N sun4-sunos5.N
sun4-sunos4.N sun4
Here are some options that you should specify (if appropriate) when
you run `configure':
`--with-gnu-ld'
Use this option if you plan to use GNU `ld' to link programs with
the GNU C Library. (We strongly recommend that you do.) This
option enables use of features that exist only in GNU `ld'; so if
you configure for GNU `ld' you must use GNU `ld' *every time* you
link with the GNU C Library, and when building it.
`--with-gnu-as'
Use this option if you plan to use the GNU assembler, `gas', when
building the GNU C Library. On some systems, the library may not
build properly if you do *not* use `gas'.
`--nfp'
Use this option if your computer lacks hardware floating point
support.
`--prefix=DIRECTORY'
Install machine-independent data files in subdirectories of
`DIRECTORY'. (You can also set this in `configparms'; see below.)
`--exec-prefix=DIRECTORY'
Install the library and other machine-dependent files in
subdirectories of `DIRECTORY'. (You can also set this in
`configparms'; see below.)
The simplest way to run `configure' is to do it in the directory
that contains the library sources. This prepares to build the library
in that very directory.
You can prepare to build the library in some other directory by going
to that other directory to run `configure'. In order to run configure,
you will have to specify a directory for it, like this:
mkdir sun4
cd sun4
../configure sparc-sun-sunos4.1
`configure' looks for the sources in whatever directory you specified
for finding `configure' itself. It does not matter where in the file
system the source and build directories are--as long as you specify the
source directory when you run `configure', you will get the proper
results.
This feature lets you keep sources and binaries in different
directories, and that makes it easy to build the library for several
different machines from the same set of sources. Simply create a build
directory for each target machine, and run `configure' in that
directory specifying the target machine's configuration name.
The library has a number of special-purpose configuration parameters.
These are defined in the file `Makeconfig'; see the comments in that
file for the details.
But don't edit the file `Makeconfig' yourself--instead, create a
file `configparms' in the directory where you are building the library,
and define in that file the parameters you want to specify.
`configparms' should *not* be an edited copy of `Makeconfig'; specify
only the parameters that you want to override. To see how to set these
parameters, find the section of `Makeconfig' that says "These are the
configuration variables." Then for each parameter that you want to
change, copy the definition from `Makeconfig' to your new `configparms'
file, and change the value as appropriate for your system.
It is easy to configure the GNU C library for cross-compilation by
setting a few variables in `configparms'. Set `CC' to the
cross-compiler for the target you configured the library for; it is
important to use this same `CC' value when running `configure', like
this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler
to use for for programs run on the build system as part of compiling
the library. You may need to set `AR' and `RANLIB' to cross-compiling
versions of `ar' and `ranlib' if the native tools are not configured to
work with object files for the target you configured for.
Some of the machine-dependent code for some machines uses extensions
in the GNU C compiler, so you may need to compile the library with GCC.
(In fact, all of the existing complete ports require GCC.)
The current release of the C library contains some header files that
the compiler normally provides: `stddef.h', `stdarg.h', and several
files with names of the form `va-MACHINE.h'. The versions of these
files that came with older releases of GCC do not work properly with
the GNU C library. The `stddef.h' file in release 2.2 and later of GCC
is correct. If you have release 2.2 or later of GCC, use its version
of `stddef.h' instead of the C library's. To do this, put the line
`override stddef.h =' in `configparms'. The other files are corrected
in release 2.3 and later of GCC. `configure' will automatically detect
whether the installed `stdarg.h' and `va-MACHINE.h' files are
compatible with the C library, and use its own if not.
There is a potential problem with the `size_t' type and versions of
GCC prior to release 2.4. ANSI C requires that `size_t' always be an
unsigned type. For compatibility with existing systems' header files,
GCC defines `size_t' in `stddef.h' to be whatever type the system's
`sys/types.h' defines it to be. Most Unix systems that define `size_t'
in `sys/types.h', define it to be a signed type. Some code in the
library depends on `size_t' being an unsigned type, and will not work
correctly if it is signed.
The GNU C library code which expects `size_t' to be unsigned is
correct. The definition of `size_t' as a signed type is incorrect.
Versions 2.4 and later of GCC always define `size_t' as an unsigned
type, and GCC's `fixincludes' script massages the system's
`sys/types.h' so as not to conflict with this.
In the meantime, we work around this problem by telling GCC
explicitly to use an unsigned type for `size_t' when compiling the GNU C
library. `configure' will automatically detect what type GCC uses for
`size_t' arrange to override it if necessary.
To build the library, type `make lib'. This will produce a lot of
output, some of which looks like errors from `make' (but isn't). Look
for error messages from `make' containing `***'. Those indicate that
something is really wrong.
To build and run some test programs which exercise some of the
library facilities, type `make tests'. This will produce several files
with names like `PROGRAM.out'.
To format the `GNU C Library Reference Manual' for printing, type
`make dvi'. To format the Info version of the manual for on line
reading with `C-h i' in Emacs or with the `info' program, type
`make info'.
To install the library and its header files, and the Info files of
the manual, type `make install', after setting the installation
directories in `configparms'. This will build things if necessary,
before installing them.
Reporting Bugs
==============
There are probably bugs in the GNU C library. There are certainly
errors and omissions in this manual. If you report them, they will get
fixed. If you don't, no one will ever know about them and they will
remain unfixed for all eternity, if not longer.
To report a bug, first you must find it. Hopefully, this will be the
hard part. Once you've found a bug, make sure it's really a bug. A
good way to do this is to see if the GNU C library behaves the same way
some other C library does. If so, probably you are wrong and the
libraries are right (but not necessarily). If not, one of the libraries
is probably wrong.
Once you're sure you've found a bug, try to narrow it down to the
smallest test case that reproduces the problem. In the case of a C
library, you really only need to narrow it down to one library function
call, if possible. This should not be too difficult.
The final step when you have a simple test case is to report the bug.
When reporting a bug, send your test case, the results you got, the
results you expected, what you think the problem might be (if you've
thought of anything), your system type, and the version of the GNU C
library which you are using. Also include the files `config.status'
and `config.make' which are created by running `configure'; they will
be in whatever directory was current when you ran `configure'.
If you think you have found some way in which the GNU C library does
not conform to the ANSI and POSIX standards (*note Standards and
Portability::.), that is definitely a bug. Report it!
Send bug reports to the Internet address `bug-glibc@prep.ai.mit.edu'
or the UUCP path `mit-eddie!prep.ai.mit.edu!bug-glibc'. If you have
other problems with installation or use, please report those as well.
If you are not sure how a function should behave, and this manual
doesn't tell you, that's a bug in the manual. Report that too! If the
function's behavior disagrees with the manual, then either the library
or the manual has a bug, so report the disagreement. If you find any
errors or omissions in this manual, please report them to the Internet
address `bug-glibc-manual@prep.ai.mit.edu' or the UUCP path
`mit-eddie!prep.ai.mit.edu!bug-glibc-manual'.
Adding New Functions
====================
The process of building the library is driven by the makefiles, which
make heavy use of special features of GNU `make'. The makefiles are
very complex, and you probably don't want to try to understand them.
But what they do is fairly straightforward, and only requires that you
define a few variables in the right places.
The library sources are divided into subdirectories, grouped by
topic. The `string' subdirectory has all the string-manipulation
functions, `stdio' has all the standard I/O functions, etc.
Each subdirectory contains a simple makefile, called `Makefile',
which defines a few `make' variables and then includes the global
makefile `Rules' with a line like:
include ../Rules
The basic variables that a subdirectory makefile defines are:
`subdir'
The name of the subdirectory, for example `stdio'. This variable
*must* be defined.
`headers'
The names of the header files in this section of the library, such
as `stdio.h'.
`routines'
`aux'
The names of the modules (source files) in this section of the
library. These should be simple names, such as `strlen' (rather
than complete file names, such as `strlen.c'). Use `routines' for
modules that define functions in the library, and `aux' for
auxiliary modules containing things like data definitions. But the
values of `routines' and `aux' are just concatenated, so there
really is no practical difference.
`tests'
The names of test programs for this section of the library. These
should be simple names, such as `tester' (rather than complete file
names, such as `tester.c'). `make tests' will build and run all
the test programs. If a test program needs input, put the test
data in a file called `TEST-PROGRAM.input'; it will be given to
the test program on its standard input. If a test program wants
to be run with arguments, put the arguments (all on a single line)
in a file called `TEST-PROGRAM.args'.
`others'
The names of "other" programs associated with this section of the
library. These are programs which are not tests per se, but are
other small programs included with the library. They are built by
`make others'.
`install-lib'
`install-data'
`install'
Files to be installed by `make install'. Files listed in
`install-lib' are installed in the directory specified by `libdir'
in `configparms' or `Makeconfig' (*note Installation::.). Files
listed in `install-data' are installed in the directory specified
by `datadir' in `configparms' or `Makeconfig'. Files listed in
`install' are installed in the directory specified by `bindir' in
`configparms' or `Makeconfig'.
`distribute'
Other files from this subdirectory which should be put into a
distribution tar file. You need not list here the makefile itself
or the source and header files listed in the other standard
variables. Only define `distribute' if there are files used in an
unusual way that should go into the distribution.
`generated'
Files which are generated by `Makefile' in this subdirectory.
These files will be removed by `make clean', and they will never
go into a distribution.
`extra-objs'
Extra object files which are built by `Makefile' in this
subdirectory. This should be a list of file names like `foo.o';
the files will actually be found in whatever directory object
files are being built in. These files will be removed by
`make clean'. This variable is used for secondary object files
needed to build `others' or `tests'.
Porting the GNU C Library
=========================
The GNU C library is written to be easily portable to a variety of
machines and operating systems. Machine- and operating system-dependent
functions are well separated to make it easy to add implementations for
new machines or operating systems. This section describes the layout of
the library source tree and explains the mechanisms used to select
machine-dependent code to use.
All the machine-dependent and operating system-dependent files in the
library are in the subdirectory `sysdeps' under the top-level library
source directory. This directory contains a hierarchy of
subdirectories (*note Hierarchy Conventions::.).
Each subdirectory of `sysdeps' contains source files for a
particular machine or operating system, or for a class of machine or
operating system (for example, systems by a particular vendor, or all
machines that use IEEE 754 floating-point format). A configuration
specifies an ordered list of these subdirectories. Each subdirectory
implicitly appends its parent directory to the list. For example,
specifying the list `unix/bsd/vax' is equivalent to specifying the list
`unix/bsd/vax unix/bsd unix'. A subdirectory can also specify that it
implies other subdirectories which are not directly above it in the
directory hierarchy. If the file `Implies' exists in a subdirectory,
it lists other subdirectories of `sysdeps' which are appended to the
list, appearing after the subdirectory containing the `Implies' file.
Lines in an `Implies' file that begin with a `#' character are ignored
as comments. For example, `unix/bsd/Implies' contains:
# BSD has Internet-related things.
unix/inet
and `unix/Implies' contains:
posix
So the final list is `unix/bsd/vax unix/bsd unix/inet unix posix'.
`sysdeps' has two "special" subdirectories, called `generic' and
`stub'. These two are always implicitly appended to the list of
subdirectories (in that order), so you needn't put them in an `Implies'
file, and you should not create any subdirectories under them.
`generic' is for things that can be implemented in machine-independent
C, using only other machine-independent functions in the C library.
`stub' is for "stub" versions of functions which cannot be implemented
on a particular machine or operating system. The stub functions always
return an error, and set `errno' to `ENOSYS' (Function not
implemented). *Note Error Reporting::.
A source file is known to be system-dependent by its having a
version in `generic' or `stub'; every system-dependent function should
have either a generic or stub implementation (there is no point in
having both).
If you come across a file that is in one of the main source
directories (`string', `stdio', etc.), and you want to write a machine-
or operating system-dependent version of it, move the file into
`sysdeps/generic' and write your new implementation in the appropriate
system-specific subdirectory. Note that if a file is to be
system-dependent, it *must not* appear in one of the main source
directories.
There are a few special files that may exist in each subdirectory of
`sysdeps':
`Makefile'
A makefile for this machine or operating system, or class of
machine or operating system. This file is included by the library
makefile `Makerules', which is used by the top-level makefile and
the subdirectory makefiles. It can change the variables set in the
including makefile or add new rules. It can use GNU `make'
conditional directives based on the variable `subdir' (see above)
to select different sets of variables and rules for different
sections of the library. It can also set the `make' variable
`sysdep-routines', to specify extra modules to be included in the
library. You should use `sysdep-routines' rather than adding
modules to `routines' because the latter is used in determining
what to distribute for each subdirectory of the main source tree.
Each makefile in a subdirectory in the ordered list of
subdirectories to be searched is included in order. Since several
system-dependent makefiles may be included, each should append to
`sysdep-routines' rather than simply setting it:
sysdep-routines := $(sysdep-routines) foo bar
`Subdirs'
This file contains the names of new whole subdirectories under the
top-level library source tree that should be included for this
system. These subdirectories are treated just like the
system-independent subdirectories in the library source tree, such
as `stdio' and `math'.
Use this when there are completely new sets of functions and header
files that should go into the library for the system this
subdirectory of `sysdeps' implements. For example,
`sysdeps/unix/inet/Subdirs' contains `inet'; the `inet' directory
contains various network-oriented operations which only make sense
to put in the library on systems that support the Internet.
`Dist'
This file contains the names of files (relative to the
subdirectory of `sysdeps' in which it appears) which should be
included in the distribution. List any new files used by rules in
the `Makefile' in the same directory, or header files used by the
source files in that directory. You don't need to list files that
are implementations (either C or assembly source) of routines
whose names are given in the machine-independent makefiles in the
main source tree.
`configure'
This file is a shell script fragment to be run at configuration
time. The top-level `configure' script uses the shell `.' command
to read the `configure' file in each system-dependent directory
chosen, in order. The `configure' files are often generated from
`configure.in' files using Autoconf.
A system-dependent `configure' script will usually add things to
the shell variables `DEFS' and `config_vars'; see the top-level
`configure' script for details. The script can check for
`--with-PACKAGE' options that were passed to the top-level
`configure'. For an option `--with-PACKAGE=VALUE' `configure'
sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE
converted to underscores) to VALUE; if the option is just
`--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to
`yes'.
`configure.in'
This file is an Autoconf input fragment to be processed into the
file `configure' in this subdirectory. *Note Introduction:
(autoconf.info)Introduction, for a description of Autoconf. You
should write either `configure' or `configure.in', but not both.
The first line of `configure.in' should invoke the `m4' macro
`GLIBC_PROVIDES'. This macro does several `AC_PROVIDE' calls for
Autoconf macros which are used by the top-level `configure'
script; without this, those macros might be invoked again
unnecessarily by Autoconf.
That is the general system for how system-dependencies are isolated.
Layout of the `sysdeps' Directory Hierarchy
-------------------------------------------
A GNU configuration name has three parts: the CPU type, the
manufacturer's name, and the operating system. `configure' uses these
to pick the list of system-dependent directories to look for. If the
`--nfp' option is *not* passed to `configure', the directory
`MACHINE/fpu' is also used. The operating system often has a "base
operating system"; for example, if the operating system is `sunos4.1',
the base operating system is `unix/bsd'. The algorithm used to pick
the list of directories is simple: `configure' makes a list of the base
operating system, manufacturer, CPU type, and operating system, in that
order. It then concatenates all these together with slashes in
between, to produce a directory name; for example, the configuration
`sparc-sun-sunos4.1' results in `unix/bsd/sun/sparc/sunos4.1'.
`configure' then tries removing each element of the list in turn, so
`unix/bsd/sparc' and `sun/sparc' are also tried, among others. Since
the precise version number of the operating system is often not
important, and it would be very inconvenient, for example, to have
identical `sunos4.1.1' and `sunos4.1.2' directories, `configure' tries
successively less specific operating system names by removing trailing
suffixes starting with a period.
As an example, here is the complete list of directories that would be
tried for the configuration `sparc-sun-sunos4.1' (without the `--nfp'
option):
sparc/fpu
unix/bsd/sun/sunos4.1/sparc
unix/bsd/sun/sunos4.1
unix/bsd/sun/sunos4/sparc
unix/bsd/sun/sunos4

Different machine architectures are conventionally subdirectories at
the top level of the `sysdeps' directory tree. For example,
`sysdeps/sparc' and `sysdeps/m68k'. These contain files specific to
those machine architectures, but not specific to any particular
operating system. There might be subdirectories for specializations of
those architectures, such as `sysdeps/m68k/68020'. Code which is
specific to the floating-point coprocessor used with a particular
machine should go in `sysdeps/MACHINE/fpu'.
There are a few directories at the top level of the `sysdeps'
hierarchy that are not for particular machine architectures.
`generic'
`stub'
As described above (*note Porting::.), these are the two
subdirectories that every configuration implicitly uses after all
others.
`ieee754'
This directory is for code using the IEEE 754 floating-point
format, where the C type `float' is IEEE 754 single-precision
format, and `double' is IEEE 754 double-precision format. Usually
this directory is referred to in the `Implies' file in a machine
architecture-specific directory, such as `m68k/Implies'.
`posix'
This directory contains implementations of things in the library in
terms of POSIX.1 functions. This includes some of the POSIX.1
functions themselves. Of course, POSIX.1 cannot be completely
implemented in terms of itself, so a configuration using just
`posix' cannot be complete.
`unix'
This is the directory for Unix-like things. *Note Porting to
Unix::. `unix' implies `posix'. There are some special-purpose
subdirectories of `unix':
`unix/common'
This directory is for things common to both BSD and System V
release 4. Both `unix/bsd' and `unix/sysv/sysv4' imply
`unix/common'.
`unix/inet'
This directory is for `socket' and related functions on Unix
systems. The `inet' top-level subdirectory is enabled by
`unix/inet/Subdirs'. `unix/common' implies `unix/inet'.
`mach'
This is the directory for things based on the Mach microkernel
from CMU (including the GNU operating system). Other basic
operating systems (VMS, for example) would have their own
directories at the top level of the `sysdeps' hierarchy, parallel
to `unix' and `mach'.
Porting the GNU C Library to Unix Systems
-----------------------------------------
Most Unix systems are fundamentally very similar. There are
variations between different machines, and variations in what
facilities are provided by the kernel. But the interface to the
operating system facilities is, for the most part, pretty uniform and
simple.
The code for Unix systems is in the directory `unix', at the top
level of the `sysdeps' hierarchy. This directory contains
subdirectories (and subdirectory trees) for various Unix variants.
The functions which are system calls in most Unix systems are
implemented in assembly code in files in `sysdeps/unix'. These files
are named with a suffix of `.S'; for example, `__open.S'. Files ending
in `.S' are run through the C preprocessor before being fed to the
assembler.
These files all use a set of macros that should be defined in
`sysdep.h'. The `sysdep.h' file in `sysdeps/unix' partially defines
them; a `sysdep.h' file in another directory must finish defining them
for the particular machine and operating system variant. See
`sysdeps/unix/sysdep.h' and the machine-specific `sysdep.h'
implementations to see what these macros are and what they should do.
The system-specific makefile for the `unix' directory (that is, the
file `sysdeps/unix/Makefile') gives rules to generate several files
from the Unix system you are building the library on (which is assumed
to be the target system you are building the library *for*). All the
generated files are put in the directory where the object files are
kept; they should not affect the source tree itself. The files
generated are `ioctls.h', `errnos.h', `sys/param.h', and `errlist.c'
(for the `stdio' section of the library).
Contributors to the GNU C Library
=================================
The GNU C library was written almost entirely by Roland McGrath, who
now maintains it. Some parts of the library were contributed or worked
on by other people.
* The `getopt' function and related code were written by Richard
Stallman, David J. MacKenzie, and Roland McGrath.
* Most of the math functions are taken from 4.4 BSD; they have been
modified only slightly to work with the GNU C library. The
Internet-related code (most of the `inet' subdirectory) and several
other miscellaneous functions and header files have been included
with little or no modification.

* The random number generation functions `random', `srandom',
`setstate' and `initstate', which are also the basis for the
`rand' and `srand' functions, were written by Earl T. Cohen for
the University of California at Berkeley and are copyrighted by the
Regents of the University of California. They have undergone minor
changes to fit into the GNU C library and to fit the ANSI C
standard, but the functional code is Berkeley's.
* The merge sort function `qsort' was written by Michael J. Haertel.
* The quick sort function used as a fallback by `qsort' was written
by Douglas C. Schmidt.
* The memory allocation functions `malloc', `realloc' and `free' and
related code were written by Michael J. Haertel.
* Fast implementations of many of the string functions (`memcpy',
`strlen', etc.) were written by Torbjorn Granlund.
* Some of the support code for Mach is taken from Mach 3.0 by CMU,
and is under the following copyright terms:

GNU C Library NEWS -- history of user-visible changes. 26 January 1995
Copyright (C) 1992, 1993, 1994, 1995 Free Software Foundation, Inc.
See the end for copying conditions.
Please send GNU C library bug reports to bug-glibc@prep.ai.mit.edu.
Version 1.10
* The library has changed from using GNU ld symbol aliases to using weak
symbols where available. The ELF object file format supports weak
symbols; GNU ld also supports weak symbols in the a.out format. (There
is also now support for other GNU ld extensions in ELF. Use the
`--with-elf' option to configure to indicate you have elf, and
`--with-gnu-ld' if using GNU ld.) This changed resulted in the deletion
of many files which contained only symbol aliases, reducing the size of
the source and the compiled library; many other files were renamed to
less cryptic names previously occupied by the symbol alias files.
* The pgrp functions have been regularized, slightly incompatibly but much
less confusingly. The core functions are now `getpgid' and `setpgid',
which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
argument) and BSD `setpgrp' (identical to `setpgid') functions are
provided for compatibility. There is no longer an incompatible `getpgrp'
with an argument declared under _BSD_SOURCE; no BSD code uses it.
* The new header file <fts.h> and suite of functions simplify programs that
operate on directory trees. This code comes from 4.4 BSD.
* Converted to Autoconf version 2, so `configure' has more options.
Run `configure --help' to see the details.
* The resolver code has been updated from the BIND-4.9.3-BETA14 release.
* The new function `malloc_find_object_address' finds the starting address
of a malloc'd block, given any address within the block. This can be
useful for debugging.
* The new functions `strtoq' and `strtouq' parse integer values from
strings, like `strtol' and `strtoul', but they return `long long int' and
`unsigned long long int' values, respectively (64-bit quantities).
* There is a new malloc debugging hook `__memalign_hook'.
* There are new typedefs `ushort' for `unsigned short int' and `uint' for
`unsigned int' in <sys/types.h>. These are for compatibility only and
their use is discouraged.
* The `-lmcheck' library to enable standard malloc debugging hooks is now
done differently, so that it works even without GNU ld.
Version 1.09
* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
* The new function `daemon' from 4.4 BSD is useful for server programs that
want to put themselves in the background.
* Joel Sherrill has contributed support for several standalone boards that
run without an operating system.
* `printf', `scanf' and friends now accept a `q' type modifier for long
long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
* All of the code taken from BSD (notably most of the math and networking
routines) has been updated from the BSD 4.4-Lite release.
* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
* The new functions `getdomainname' and `setdomainname' fetch or change the
YP/NIS domain name. These are system calls which exist on systems which
have YP (aka NIS).
* The time zone data files have been updated for the latest international
conventions.
* The SunRPC programs `portmap' and `rpcinfo' are now installed in
$(sbindir) (usually /usr/local/sbin) instead of $(bindir).
Version 1.08
* The C library now includes support for Sun RPC, from Sun's free
RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
are included. (There is still no support for YP.)
* Tom Quinn has contributed a port of the C library to SGI machines running
Irix 4 (mips-sgi-irix4).
* The new `lockf' function is a simplified interface to the locking
facilities of `fcntl', included for compatibility.
* New time functions `timegm', `timelocal', and `dysize' for compatibility.
* New header file <sys/timeb.h> and new function `ftime' for compatibility.
* New header files <poll.h> and <sys/poll.h> and new function `poll' for
compatibility.
* The error message printed by `assert' for a failed assertion now includes
the name of the program (if using GNU ld) and the name of the calling
function (with versions of GCC that support this).
* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
* The library now includes the <sys/mman.h> header file and memory
management functions `mmap', `munmap', `mprotect', `msync', and
`madvise', on systems that support those facilities.
* The interface for `mcheck' has changed slightly: the function called to
abort the program when an allocation inconsistency is detected now takes
an argument that indicates the type of failure. The new function
`mprobe' lets you request a consistency check for a particular block at
any time (checks are normally done only when you call `free' or `realloc'
on a block).
* It is now possible to easily cross-compile the C library, building on one
system a library to run on another machine and/or operating system. All
you need to do is set the variable `HOST_CC' in `configparms' to the
native compiler for programs to run on the machine you are building on (a
few generator programs are used on Unix systems); set `CC' to the
cross-compiler.
* The new function `fexecve' (only implemented on the GNU system) executes
a program file given a file descriptor already open on the file.
Version 1.07
* Brendan Kehoe has contributed most of a port to the DEC Alpha
running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
* You can set the variable `libprefix' in `configparms' to specify a prefix
to be prepended to installed library files; this makes it easy to install
the GNU C library to be linked as `-lgnuc' or whatever.
* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
copies a limited number of characters from a string, and returns the
address of the last character written.
* You no longer need to check for whether the installed `stddef.h' is
compatible with the GNU C library. configure now checks for you.
* You can now define a per-stream `fileno' function to convert the
stream's cookie into an integral file descriptor.
* ``malloc (0)'' no longer returns a null pointer. Instead, it
allocates zero bytes of storage, and returns a unique pointer which
you can pass to `realloc' or `free'. The behavior is undefined if
you dereference this pointer.
* The C library now runs on Sony NEWS m68k machines running either
NewsOS 3 or NewsOS 4.
* The new `syscall' function is a system-dependent primitive function
for invoking system calls. It has the canonical behavior on Unix
systems, including unreliable return values for some calls (such as
`pipe', `fork' and `getppid').
* The error code `EWOULDBLOCK' is now obsolete; it is always defined
to `EAGAIN', which is the preferred name. On systems whose kernels
use two distinct codes, the C library now translates EWOULDBLOCK to
EAGAIN in every system call function.
Version 1.06
* The GNU C Library Reference Manual is now distributed with the library.
`make dvi' will produce a DVI file of the printed manual.
`make info' will produce Info files that you can read on line using C-h i
in Emacs or the `info' program.
Please send comments on the manual to bug-glibc-manual@prep.ai.mit.edu.
* The library now supports SVR4 on i386s (i386-unknown-sysv4).
* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
* Jason Merrill has contributed a port to the Sequent Symmetry running
Dynix version 3 (i386-sequent-dynix).
* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
* New function `memory_warnings' lets you arrange to get warnings when
malloc is running out of memory to allocate, like Emacs gives you.
* The C library now contains the relocating allocator used in Emacs 19 for
its editing buffers. This allocator (ralloc) minimizes allocation
overhead and fragmentation by moving allocated regions around whenever it
needs to. You always refer to a ralloc'd region with a "handle" (a
pointer to a pointer--an object of type `void **').
* There is a new `printf' format: `%m' gives you the string corresponding
to the error code in `errno'.
* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
or `%[' conversion, but instead of filling in a fixed-sized buffer you
pass, the `a' modifier says to fill in a `char **' you pass with a
malloc'd string.
* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
`FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
* `mkstemp' is a traditional Unix function to atomically create and open a
uniquely-named temporary file.
Version 1.05
* The standard location for the file that says what the local timezone is
has changed again. It is now `/usr/local/etc/localtime' (or more
precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
* The distribution no longer contains any files with names longer than 14
characters.
* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
* New functions `ttyslot' and `syslog' from 4.4 BSD.
Version 1.04
* The configuration process has changed quite a bit. The `configure'
script is now used just like the configuration scripts for other GNU
packages. The `sysdeps' directory hierarchy is much rearranged.
The file `INSTALL' explains the new scheme in detail.
* The header files no longer need to be processed into ANSI C and
traditional C versions. There is just one set of files to install, and
it will work with ANSI or old C compilers (including `gcc -traditional').
* Brendan Kehoe and Ian Lance Taylor have ported the library to the
MIPS DECStation running Ultrix 4.
* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
Tom Quinn contributed the initial code. The GNU C library can NOT yet be
made itself into a shared library.
* Yet further improved support for the i386, running 4.3 BSD-like systems
(such as Mach 3 with the Unix single-server), or System V.
* New function `strncasecmp' to do case-insensitive string comparison
with limited length.
* New function `strsep' is a reentrant alternative to `strtok'.
* New functions `scandir' and `alphasort' for searching directories.
* New function `setenv' is a better interface to `putenv'.
* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
function for traversing a directory tree.
* The GNU obstack package is now also part of the C library.
The new function `open_obstack_stream' creates a stdio stream that
writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
formatted output directly to an obstack.
* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
* The new functions `strfry' and `memfrob' do mysterious and wonderful
things to your strings.
* There are some new test programs: test-fseek, testmb, and testrand.
* Some work has been done to begin porting the library to 4.4 BSD and Linux.
These ports are not finished, but are a good starting place for really
supporting those systems.
* `/etc/localtime' is now the standard location for the file that says what
the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
This follows the general principle that `/etc' is the place for all local
configuration files.
* The C library header files now use `extern "C"' when used by the C++
compiler, so the C library should now work with C++ code.
* The header file <bstring.h> is gone. <string.h> now declares bcopy,
bcmp, bzero, and ffs.
* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
function which uses the `merge sort' algorithm, and is said to be
significantly faster than the old GNU `qsort' function. Merge sort is
now the standard `qsort' function. The new algorithm can require a lot
of temporary storage; so, the old sorting function is called when the
required storage is not available.
* The C library now includes Michael Glad's Ultra Fast Crypt, which
provides the Unix `crypt' function, plus some other entry points.
Because of the United States export restriction on DES implementations,
we are distributing this code separately from the rest of the C library.
There is an extra distribution tar file just for crypt; it is called
`glibc-VERSION-crypt.tar.Z', e.g. `glibc-1.04-crypt.tar.Z'. You can just
unpack the crypt distribution along with the rest of the C library and
build; you can also build the library without getting crypt. Users
outside the USA can get the crypt distribution via anonymous FTP from
ftp.uni-c.dk [129.142.6.74], or another archive site outside the U.S.
* The code and header files taken from 4.4 BSD have been updated with the
latest files released from Berkeley.

Feature Test Macros
-------------------
The exact set of features available when you compile a source file
is controlled by which "feature test macros" you define.
If you compile your programs using `gcc -ansi', you get only the
ANSI C library features, unless you explicitly request additional
features by defining one or more of the feature macros. *Note GNU CC
Command Options: (gcc.info)Invoking GCC, for more information about GCC
options.
You should define these macros by using `#define' preprocessor
directives at the top of your source code files. These directives
*must* come before any `#include' of a system header file. It is best
to make them the very first thing in the file, preceded only by
comments. You could also use the `-D' option to GCC, but it's better
if you make the source files indicate their own meaning in a
self-contained way.
- Macro: _POSIX_SOURCE
If you define this macro, then the functionality from the POSIX.1
standard (IEEE Standard 1003.1) is available, as well as all of the
ANSI C facilities.
- Macro: _POSIX_C_SOURCE
If you define this macro with a value of `1', then the
functionality from the POSIX.1 standard (IEEE Standard 1003.1) is
made available. If you define this macro with a value of `2',
then both the functionality from the POSIX.1 standard and the
functionality from the POSIX.2 standard (IEEE Standard 1003.2) are
made available. This is in addition to the ANSI C facilities.
- Macro: _BSD_SOURCE
If you define this macro, functionality derived from 4.3 BSD Unix
is included as well as the ANSI C, POSIX.1, and POSIX.2 material.
Some of the features derived from 4.3 BSD Unix conflict with the
corresponding features specified by the POSIX.1 standard. If this
macro is defined, the 4.3 BSD definitions take precedence over the
POSIX definitions.
Due to the nature of some of the conflicts between 4.3 BSD and
POSIX.1, you need to use a special "BSD compatibility library"
when linking programs compiled for BSD compatibility. This is
because some functions must be defined in two different ways, one
of them in the normal C library, and one of them in the
compatibility library. If your program defines `_BSD_SOURCE', you
must give the option `-lbsd-compat' to the compiler or linker when
linking the program, to tell it to find functions in this special
compatibility library before looking for them in the normal C
library.
- Macro: _SVID_SOURCE
If you define this macro, functionality derived from SVID is
included as well as the ANSI C, POSIX.1, and POSIX.2 material.
- Macro: _GNU_SOURCE
If you define this macro, everything is included: ANSI C, POSIX.1,
POSIX.2, BSD, SVID, and GNU extensions. In the cases where POSIX.1
conflicts with BSD, the POSIX definitions take precedence.
If you want to get the full effect of `_GNU_SOURCE' but make the
BSD definitions take precedence over the POSIX definitions, use
this sequence of definitions:
#define _GNU_SOURCE
#define _BSD_SOURCE
#define _SVID_SOURCE
Note that if you do this, you must link your program with the BSD
compatibility library by passing the `-lbsd-compat' option to the
compiler or linker. *Note:* If you forget to do this, you may get
very strange errors at run time.
We recommend you use `_GNU_SOURCE' in new programs. If you don't
specify the `-ansi' option to GCC and don't define any of these macros
explicitly, the effect is the same as defining `_GNU_SOURCE'.
When you define a feature test macro to request a larger class of
features, it is harmless to define in addition a feature test macro for
a subset of those features. For example, if you define
`_POSIX_C_SOURCE', then defining `_POSIX_SOURCE' as well has no effect.
Likewise, if you define `_GNU_SOURCE', then defining either
`_POSIX_SOURCE' or `_POSIX_C_SOURCE' or `_SVID_SOURCE' as well has no
effect.
Note, however, that the features of `_BSD_SOURCE' are not a subset of
any of the other feature test macros supported. This is because it
defines BSD features that take precedence over the POSIX features that
are requested by the other macros. For this reason, defining
`_BSD_SOURCE' in addition to the other feature test macros does have an
effect: it causes the BSD features to take priority over the conflicting
POSIX features.

/* ANSI and traditional C compatibility macros
ANSI C is assumed if __STDC__ is #defined.
Macro ANSI C definition Traditional C definition
----- ---- - ---------- ----------- - ----------
PTR `void *' `char *'
LONG_DOUBLE `long double' `double'
CONST `const' `'
VOLATILE `volatile' `'
SIGNED `signed' `'
PTRCONST `void *const' `char *'
DEFUN(name, arglist, args)
Defines function NAME.
ARGLIST lists the arguments, separated by commas and enclosed in
parentheses. ARGLIST becomes the argument list in traditional C.
ARGS list the arguments with their types. It becomes a prototype in
ANSI C, and the type declarations in traditional C. Arguments should
be separated with `AND'. For functions with a variable number of
arguments, the last thing listed should be `DOTS'.
DEFUN_VOID(name)
Defines a function NAME, which takes no arguments.
EXFUN(name, prototype)
Is used in an external function declaration.
In ANSI C it is `NAMEPROTOTYPE' (so PROTOTYPE should be enclosed in
parentheses). In traditional C it is `NAME()'.
For a function that takes no arguments, PROTOTYPE should be `(NOARGS)'.
For example:
extern int EXFUN(printf, (CONST char *format DOTS));
int DEFUN(fprintf, (stream, format),
FILE *stream AND CONST char *format DOTS) { ... }
void DEFUN_VOID(abort) { ... }

The GNU C library now includes Michael Glad's Ultra Fast Crypt, which
provides the Unix `crypt' function, plus some other entry points. Because
of the United States export restriction on DES implementations, we are
distributing this code separately from the rest of the C library. There is
an extra distribution tar file just for crypt; it is called
`glibc-1.07-crypt.tar.gz'. You can just unpack the crypt distribution
along with the rest of the C library and build; you can also build the
library without getting crypt. Users outside the USA can get the crypt
distribution via anonymous FTP from ftp.uni-c.dk [129.142.6.74], or another
archive site outside the USA. Archive maintainers are encouraged to copy
this distribution to their archives outside the USA. Please get it from
ftp.uni-c.dk; transferring this distribution from prep.ai.mit.edu (or any
other site in the USA) to a site outside the USA is in violation of US
export laws.

__STRICT_ANSI__ ANSI Standard C.
_POSIX_SOURCE IEEE Std 1003.1.
_POSIX_C_SOURCE If ==1, like _POSIX_SOURCE; if ==2 add IEEE Std 1003.2.
_BSD_SOURCE ANSI, POSIX, and 4.3BSD things.
_SVID_SOURCE ANSI, POSIX, and SVID things.
_GNU_SOURCE All of the above, plus GNU extensions.
The `-ansi' switch to the GNU C compiler defines __STRICT_ANSI__.

If more than one of these are defined, they accumulate.
For example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE
together give you ANSI C, 1003.1, and 1003.2, but nothing else.
These are defined by this file and are used by the
header files to decide what to declare or define:
__USE_POSIX Define IEEE Std 1003.1 things.
__USE_POSIX2 Define IEEE Std 1003.2 things.
__USE_BSD Define 4.3BSD things.
__USE_SVID Define SVID things.
__USE_MISC Define things common to BSD and System V Unix.
__USE_GNU Define GNU extensions.
__FAVOR_BSD Favor 4.3BSD things in cases of conflict.

explicitly undefined if they are not explicitly defined.

Status of Hurd support in libc. Last updated 22 Nov 1994.
Roland McGrath <roland@gnu.ai.mit.edu>
Everything not noted below is implemented, most of it tested. There are
various very small things unfinished or thought to be perhaps wrong
throughout the code, marked by comments containing `XXX'.
* Signals and job control work, but are a very hairy area.
There are various ways the signal thread can block and fail
to respond when the program is losing badly.
* We are not sure about possible races between setpgrp (A, pgrp) from
process B vs process A receiving proc_newids.
* The rest of libc (stdio et al) is not safe for multithreaded programs.
mutex locks should be added to various things.
* Recovery from faults in the signal thread is not implemented yet.
* longjmp needs to clean up reply port, intr_port; needs thought about.
* Cooperation with cthreads is not finished. If you link with cthreads,
libc internal code still does not use real condition variables.
sigsuspend currently does a busy wait where it should use a condition.
Signal state is per kernel thread; for unwired cthreads it should be per
cthread instead.
* sigaltstack/sigstack do not really work: the signal stack needs thread
variables and cthread data set up, which is not done.
* malloc is a kludge.
* Nothing uses mapped io. Eventually stdio and read/write/seek should. I
have written a little code for this, but it is far from finished.
* Resource limits do not really work; current implementation is patchy and
inconsistent.
* libc implicitly uses some environment variables. This is a security
problem for setuid exec. Probably crt0 should remove the variables from
the environment if setuid.
* The miscellaneous msg.defs calls are only partially implemented.
* The default SIGINFO handler needs to be written.
* File locking is not implemented; the RPC interface is not there yet.
* The current getitimer/setitimer implementation is a kludge.
* mmap cannot do MAP_NOEXTEND.
* Unimplemented calls (from the 4.4 system call list):
