Threads is a library designed to make threading under C++ simpler. It provides a "pthread" class, with an abstract method called "thread". It also provides classes for mutual exclusion of parallel processes and condition signalling, and a semaphore class that comes in handy when synchronizing constructor and threaded method. The aim of the threads library is to provide a simple, yet powerful means of threading applcations, and to provide shared memory and process scoping to C++ programs.
