Pth -- The GNU Portable Threads 1.2b3 Copy Policy: GNU/GPL Pth is a very portable POSIX/ANSI-C-based library for Unix platforms which provides non-preemptive scheduling for multiple threads of execution ("multithreading") inside server applications. All threads run in the same address space of the server application, but each thread has its own individual program-counter, run-time stack, signal mask and errno variable. The thread scheduling itself is done in a cooperative way, i.e., the threads are managed by a priority- and event-based non-preemptive scheduler. The intention is that this way one can achieve better portability and run-time performance than with preemptive scheduling. The event facility allows threads to wait until various types of events occur, including pending I/O on filedescriptors, asynchronous signals, elapsed timers, pending I/O on message ports, thread and process termination, and even customized callback functions. Additionally, Pth provides an optional emulation API for POSIX.1c threads ("pthreads") which can be used for backward compatibility to existing multithreaded applications.
