UNIX(R), POSIX, and Open Systems: The Open Standards Puzzle

The rapid growth of the UNIX market has resulted in a diversity of implementations of the operating system. To promote application and user portability, standards have been developed to remove incompatibilities among systems. This book will explain how the various UNIX standards have been developed and how they interrelate. The book gives programmers, marketing managers, sales managers, and system developers a place to turn before tackling the actual standards documentation--with complete overviews of the IEEE 1003 set of standards for operating system interfaces, facilities, and languages all commonly known as POSIX, as well as related UNIX communication standards.
