Hi everyone, there is an insteresting article about RTLinux on Dr. Dobb's Journal called "Linux, Real-time Linux, & IPC" (I'm sorry if this article was mentioned before on this list !!!) url: http://www.ddj.com/articles/1999/9911/9911b/9911b.htm Abstract: When dealing with real-time systems, the overhead of interprocess communications (IPC) becomes important. The formalized structures that are used in Linux for IPC can carry with them a significant amount of overhead. This can create timing problems for your applications. In this article, I'll examine two of the best IPC mechanisms available under Linux -- FIFOs and shared memory. - Juanjo Marín --- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] ---- For more information on Real-Time Linux see: http://www.rtlinux.org/~rtlinux/
