Interprocess Communications in UNIX: The Nooks and Crannies / Edition 2

Understanding processes is fundamental to understanding UNIX. This book zeroes right in on the key techniques of processes and interprocess communication (IPC) - from primitive communications to the complexities of sockets.Loaded with examples and illustrations that clarify each technique, Interprocess Communications in UNIX covers topics like: beginning and ending processes; using fork and exec together; using primitive communications; and working with both named and unnamed pipes. Learn how to create message queues; use remote procedure calls (RPCs); create and access semaphore sets; and create shared memory segments. Once you attain a thorough mastery of interprocess communication methodologies, using POSIX threads you'll learn communications techniques for multithreaded applications. Learn to handle multiple threads in both single and multiple processes. From beginning to end, the book truly leads you through the "nooks and crannies" of UNIX - making you a dramatically more effective programmer.
