From 48e1819573faee474368a5e59bdf3e75de90530f Mon Sep 17 00:00:00 2001 From: "Ralf S. Engelschall" Date: Sun, 23 May 1999 14:54:10 +0000 Subject: Import of NPS, a non-preeemtive thread scheduling library. 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.
