  The GNU C Library - Introduction
The GNU C library defines some of the facilities required by the SVID that are not also required by the ANSI or POSIX standards, for compatibility with System V Unix and other Unix systems (such as SunOS) which include these facilities.
The GNU C library header files have been written in such a way that it doesn't matter if a header file is accidentally included more than once; including a header file a second time has no effect.
Some library facilities, such as those for dealing with variadic arguments (see section Variadic Functions) and non-local exits (see section Non-Local Exits), actually require a considerable amount of cooperation on the part of the C compiler, and implementationally it might be easier for the compiler to treat these as built-in parts of the language.

 GNU C Library - GNU Project - Free Software Foundation (FSF)
The GNU C library is used as the C library in the GNU system and most systems with the Linux kernel.
The GNU C library is primarily designed to be a portable and high performance C library.
In 2001 The GNU C Library Steering Committee , was formed and currently consists of Mark Brown, Paul Eggert, Andreas Jaeger, Jakub Jelinek, Roland McGrath and Andreas Schwab.

 The GNU C Library: Language Features
Some of the facilities implemented by the C library really should be thought of as parts of the C language itself.
These facilities ought to be documented in the C Language Manual, not in the library manual; but since we don't have the language manual yet, and documentation for these features has been written, we are publishing it here.
In practice, the GNU C compiler always passes a given set of argument types in the same way regardless of whether they are optional or required.

 The GNU C Library
The GNU C library includes several header files, each of which provides definitions and declarations for a group of related facilities; this information is used by the C compiler when processing your program.
The GNU C library defines some of the facilities required by the SVID that are not also required by the ISO C or POSIX standards, for compatibility with System V Unix and other Unix systems (such as SunOS) which include these facilities.
In the GNU system, opening a file returns this error when the file is translated by a program and the translator program dies while starting up, before it has connected to the file.

 The GNU C Library - Installing the GNU C Library
GNU libc can be compiled in the source directory, but we strongly advise building it in a separate build directory.
If you are installing glibc as your primary C library, we recommend that you shut the system down to single-user mode first, and reboot afterward.
If you think you have found some way in which the GNU C library does not conform to the ISO and POSIX standards (see section Standards and Portability), that is definitely a bug.

 The GNU C Library - Error Reporting
Many functions in the GNU C library detect and report error conditions, and sometimes your programs need to check for these error conditions.
Many library functions are guaranteed to set it to certain nonzero values when they encounter certain kinds of errors.
The library has functions and variables designed to make it easy for your program to report informative error messages in the customary format about the failure of a library call.

 The GNU C Library - Introduction
The GNU C library, described in this document, defines all of the library functions that are specified by the ISO C standard, as well as additional features specific to POSIX and other derivatives of the Unix operating system, and extensions specific to the GNU system.
The GNU C library includes several header files, each of which provides definitions and declarations for a group of related facilities; this information is used by the C compiler when processing your program.
The GNU C library defines most of the facilities required by the SVID that are not also required by the ISO C or POSIX standards, for compatibility with System V Unix and other Unix systems (such as SunOS) which include these facilities.

 The GNU C Library - Library Maintenance
If you think you have found some way in which the GNU C library does not conform to the ANSI and POSIX standards (see section Standards and Portability), that is definitely a bug.
The GNU C library is written to be easily portable to a variety of machines and operating systems.
The GNU C library was written almost entirely by Roland McGrath, who now maintains it.

 The GNU C++ Iostream Library
The iostream classes implement most of the features of AT&T version 2.0 iostream library classes, and most of the features of the ANSI X3J16 library draft (which is based on the AT&T design).
As a special exception, if you link this library with files compiled with a GNU compiler to produce an executable, this does not cause the resulting executable to be covered by the GNU General Public License.
Although these definitions come from a library, rather than being part of the ``core language'', they are sufficiently central to be specified in the latest working papers for C++.

 The GNU C Library - Installation
Installation of the GNU C library is relatively simple.
in the directory where you are building the library, and define in that file the parameters you want to specify.
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.

 Override the GNU C library -- painlessly
This is not for the faint of heart, however, because although the API is well documented, the internal organization of the GNU C library is not.
These libraries can be either complete replacements (that is, a private version of glibc) or subsets -- even a single function.
Writing private versions of GNU C library functions is a great way to debug systems problems or make quick fixes.

 The GNU C Library
Many library functions are guaranteed to set it to certain nonzero values when they encounter certain kinds of errors.
In the GNU system, this error can happen for many calls when the object does not support the particular operation; it is a generic indication that the server knows nothing to do for that call.
In the GNU system, opening a file returns this error when the file is translated by a program and the translator program dies while starting up, before it has connected to the file.

This is in addition to the ISO C facilities.
The problem is that the standardization of the thread safe C library interface still is behind.

 The GNU C Library
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.
The obstack facility works with all C compilers, including both 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 non-ISO C compiler, all the obstack "functions" are actually defined only as macros.
This is the same situation that exists in ISO C for the standard library functions.

 The GNU C Library   (Site not responding. Last check: 2007-10-20)
Libraries for use by C programs really consist of two parts: header files that define types and macros and declare variables and functions; and the actual library or archive that contains the definitions of the variables and functions.
This is so that the compiler has declarations of these facilities available and can correctly process references to them.
The GNU C library provides several header files, each of which contains the type and macro definitions and variable and function declarations for a group of related facilities.
