Do you mean: Calls kill(2,SIG). kill(3,SIG)....what system call is being used. It is definitely not signal() since that is the system call for installing a signal handler. I would look at the code in kernel/signal.c This has the "kill" system call which appears to do all its dirty work in __send_signal(). -- John -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
