GNU C Library

https://www.gnu.org/software/libc/
Library for use with GNU/Hurd and GNU/Linux

The GNU C Library (glibc) is the standard C library of the GNU system. It defines the system calls and other basic functionality necessary to write programs in the C language. It handles low-level functionality that communicates with the kernel, such as process and file management, as well as higher-level functionality such as string manipulation or command-line argument handling.

In GNU/Linux distributions, the C library works with the Linux kernel to implement the operating system behavior seen by user applications. In GNU/Hurd, it works with a microkernel and Hurd servers.

The GNU C Library implements much of the POSIX.1 functionality in the GNU system, using configurations i[4567]86-*-gnu. The current GNU/Hurd support requires out-of-tree patches that will eventually be incorporated into an official GNU C Library release.

It is one of the most important components of the GNU operating system and its variants GNU/Linux. It is used by almost all C programs and provides the most essential program interface.
