Engelschall <rse@engelschall.com> -GNU 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 it's own -individual program-counter, run-time stack, signal mask and errno variable. +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. +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.
