Engelschall <rse@engelschall.com> + +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 documentation and latest release can be found on + o http://www.gnu.org/software/pth/ + o ftp://ftp.gnu.org/gnu/pth/ |
