With this practical book, you will attain a solid understanding of threads and will discover how toput this powerful mode of programming to work in real-world applications. The primary advantageof threaded programming is that it enables your applications to accomplish more than one task atthe same time by using the number-crunching power of multiprocessor parallelism and byautomatically exploiting I/O concurrency in your code, even on a single processor machine. Theresult: applications that are faster, more responsive to users, and often easier to maintain.Threaded programming is particularly well suited to network programming where it helps alleviatethe bottleneck of slow network I/O. В This book offers an in-depth description of the IEEEoperating system interface standard, POSIXAE (Portable Operating System Interface) threads,commonly called Pthreads. Written for experienced C programmers, but assuming no previousknowledge of threads, the book explains basic concepts such as asynchronous programming, thelifecycle of a thread, and synchronization.
