The SRR Module (srripc) is a synchronous message-passing module for the Linux kernel versions 2.2.x, 2.4.x, and 2.6.x. This module provides synchronous message passing among processes and threads, queued asynchronous event notification (proxies), timed delivery of proxies and signals, triggering of proxies between tasks, and user-space interrupt handling. Synchronous message passing is a fast, flexible, and robust IPC mechanism, particularly useful for building modular systems. The SRR Module installs automatically and provides an API that allows for porting of applications between QNX and Linux.
