## pth-2.0.7p1 – GNU portable threads

## Description

    GNU Pth - GNU Portable Threads

    Pth is a very portable POSIX/ANSI-C based library for Unix platforms
    which provides non-preemptive priority-based 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 it's 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.
