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 file descriptors, -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.") + "Pth is a portable library providing non-preemptive, priority-based +scheduling for multiple execution threads.
