POSIX Realtime Extensions

POSIX real-time extensions (based on POSIX 1003.1b ) define extensions such as timers, priority scheduling, real-time signals, semaphores, memory queues, shared memory and memory locking that are useful for development of real-time systems. Extensions such as, timers and shared memory are supported by the Librt library , which conforms to the Linux Standard Base (LSB) 3.1 Specification. The Symbian platform supports the Librt library, which enables Symbian Developers to port Librt-based applications onto the Symbian platform quickly and easily.
