Hi, how do I go about detecting when a user quits a program by dropping their connection via a network ? Also, is it possible to write a signal handler for a SIGKILL which gets executed when a SIGKILL is received but doesn't stop the impending death ? any help would be appreciated, thanks.. darrenr@mullauna.cs.mu.oz.au

If the networking support is any good, you should get a SIGHUP. >Also, is it possible to write a signal handler for a SIGKILL which gets >executed when a SIGKILL is received but doesn't stop the impending death ? No, SIGKILL cannot be caught or ignored (as the manual says!) SIGKILL is normally sent only as a last resort; SIGTERM is considered a better way to try to kill a process. SIGTERM can be caught.
