Professional Multicore Programming: Design and Implementation for C++ Developers

Appendix D. POSIX Standard for Process Management

This appendix contains sections from the POSIX Standard for Process Management. Portable Operating System Interface (POSIX) is the open operating system interface standard accepted worldwide. It is produced by IEEE and recognized by ISO and ANSI. Support of POSIX standards ensures code portability between systems and is increasingly mandated for commercial applications and government contracts. The POSIX Standard is the most widely available method for cross-platform multicore development. It is compatible with high-level libraries such as the Standard Template Adaptive Parallel Library (STAPL) and new Standard C++0x. The POSIX Standard is voluminous, containing thousands of pages. Here, for your convenience, are selected sections from the standard on process management. The API functions contained in these selected sections were either covered in this book or are of concern when developing multicore applications.
