The C Standard Library is the standard library for the C programming language, as specified in the ANSI C standard. It was developed at the same time as the C POSIX library, which is basically a superset of it. Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C library.
Informally, the terms C standard library or C library or libc are also used to designate a particular implementation on a given system. In the Unix environment, such an implementation is usually shipped with the operating system and its presence is assumed by many applications. For instance, GNU/Linux comes with the GNU implementation glibc.
The C standard library provides macros, type definitions, and functions for tasks like string handling, mathematical computations, input/output processing, memory allocation and several other operating system services.
