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.
