This completely revised and updated edition presents a comprehensive treatment of every form of interprocess communication (ipc), including message passing, synchronization, shared memory, and remote procedure calls (rpcs). Well-implemented ipcs are the key to the performance of virtually every nontrivial unix program. The book begins with a basic introduction to ipc and the problems it is expected to solve. Along the way, the reader is introduced to every current ipc technique and technology, including: pipes and fifos posix and system v message queues mutexes and condition variables read-write locks record locking posix and system v semaphores posix and system v shared memory solaris doors and sun rpc performance measurements of ipc techniques besides gaining an indepth understanding of these topics, the readers will develop capabilities to create implementations of posix message queues, read-write locks, and semaphores. It is an ideal text for computer science students for courses in network programming as well as a useful reference for experienced programmers. - from Amzon
