The C POSIX library is a language-independent library (using C calling conventions) that adds functions specific to POSIX systems. POSIX (and SUS) specifies a number of routines that should be available over and above those in the C standard library proper. It was developed at the same time as the ANSI C standard and is closely related to C. Some effort was made to make the C and POSIX libraries compatible, but there are a few POSIX functions that were never introduced into ANSI C.
