- C POSIX library
The C POSIX library is a language-independent library (using C
calling convention s) that adds functions specific toPOSIX 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.Facilities are often implemented alongside the
C standard library functionality, with varying degrees of closeness. For example,glibc implements functions such as fork within libc.so, but beforeNPTL was merged into glibc it constituted a separate library with its own linker flag. Often, this POSIX-specified functionality will be regarded as part of the library; the C library proper may be identified as theANSI orISO C library.C POSIX library header files
