GNU pth - GNU Portable Threads

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.
|
|
|
|
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.
