21.8 Standards

There are a number of "official" standards for the behavior of portable applications among Unix and Unix-like systems. The first two entries are the standards themselves, the next one is a guide for using the first standard. The final two entries are the formal standards for the C and C++ programming languages.

  1. ISO/IEC Standard 9945-1: 1996 [IEEE/ANSI Std 1003.1, 1996 Edition] Information Technology -- Portable Operating System Interface (POSIX) -- Part 1: System Application: Program Interface (API) [C Language] . IEEE, 1996. ISBN: 1-55937-573-6.

    This edition incorporates extensions for real-time applications (1003.1b-1993, 1003.1i-1995) and threads (1003.1c-1995). Electronic versions are available via subscription, see http://www.standards.ieee.org .

    This book describes the interface to the operating system as seen by the C or C++ programmer.

  2. ISO/IEC Standard 9945-2: 1993 [IEEE/ANSI Std 1003.2-1992 & IEEE/ANSI 1003.2a-1992] Information Technology -- Portable Operating System Interface (POSIX) -- Part 2: Shell and Utilities IEEE, 1996. ISBN: 1-55937-406-3. Includes and shipped with 1003.2d-1994.
