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.

Famous quotes containing the words standard and/or library:
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
“... as beauty is in the eye of the beholder, the ideal library is in the wish of its maker.”
—Carolyn Wells (1862–1942)
