Engelschall. + +NPS is a POSIX/ANSI-C based library for Unix platforms which +provides non-preemtive scheduling for multiple threads of execution +("multi-threading") inside server applications. All threads run in the +same address space of the server application, but each thread has it's +own individual run-time stack and program-counter. + +The thread scheduling itself is done in a cooperative way, i.e. the +threads are managed by a priority- and event-based non-preemtive +scheduler. The intention is that this way one can achieve better +portability and run-time performance than with preemtive scheduling. +The event facility allows threads to wait until various types of events +occur, including pending I/O on filedescriptors, 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 + http://www.engelschall.com/sw/nps/ + ftp://ftp.engelschall.com/sw/nps/ |
