The GNU C Library is the standard system C library for all GNU systems,
|
|
|
|
|
and is an important part of what makes up a GNU system. It provides the
|
|
|
|
|
system API for all programs written in C and C-compatible languages such
|
|
|
|
|
as C++ and Objective C; the runtime facilities of other programming
|
|
|
|
|
languages use the C library to access the underlying operating system.
|
|
|
|
|
|
|
|
|
|
In GNU/Linux systems, the C library works with the Linux kernel to
|
|
|
|
|
implement the operating system behavior seen by user applications.
|
|
|
|
|
In GNU/Hurd systems, it works with a microkernel and Hurd servers.
|
|
|
|
|
|
|
|
|
|
The GNU C Library implements much of the POSIX.1 functionality in the
|

|
|
|
GNU/Hurd system, using configurations i[4567]86-*-gnu and x86_64-gnu.

When working with Linux kernels, this version of the GNU C Library
|
2017-05-08 10:45:20 +00:00
|
|
|
requires Linux kernel version 3.2 or later.

|
|
|
|
2010-02-10 15:34:34 +00:00
|
|
|
Also note that the shared version of the libgcc_s library must be
|
|
|
|
|
installed for the pthread library to work correctly.

The GNU C Library is (almost) completely documented by the Texinfo manual
|
|
|
|
|
found in the `manual/' subdirectory. The manual is still being updated
|
|
|
|
|
and contains some known errors and omissions; we regret that we do not
|
|
|
|
|
have the resources to work on the manual as much as we would like. For
|
|
|
|
|
corrections to the manual, please file a bug in the `manual' component,
|
|
|
|
|
following the bug-reporting instructions below. Please be sure to check
|
|
|
|
|
the manual in the current development sources to see if your problem has
|
|
|
|
|
already been corrected.
