I'm trying to implement pwait. It blocks until a specified PID exits, and then it exits. You can use it to do other stuff after a program finishes. While we're on the subject, is there some way to receive notification that some aspect of a process changes (in this case, stopping using CPU, but not exiting). Thanks for the time to help me figure this out. -Joseph -- [EMAIL PROTECTED]/////////////////////////////////////////////// "There is also an entire branch in the physical therapy field dedicated to the treatment of little-finger injuries caused by excessive Emacs use." --Linux Weekly News editor (http://lwn.net/Articles/206916/) ///////260 IATL / The University of Iowa / Iowa City, IA 52242/////// - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
