Description
For programmers, system architects, and technical programmer managers.
Providing an overview of the Solaris and POSIX multithreading architectures, this book explains threads at a level that is completely accessible to programmers and system architects with no previous knowledge of threads. Covers the business and technical benefits of threaded programs, along with discussions of third party software that is threaded, pointing out the benefits.
