Grrr.... This confuses me. Can you please help me define some terminology and clear things up? 1) In regards to signals, if a signal is BLOCKED, what does that mean? 2) If a signal is IGNORED, that means that it is not CAUGHT, right? 3) If I fill a signal set with all signals and that to the signal mask, what signals are caught by that thread? 4) I'm trying to figure out what parameters I need for pthread_sigmask () and similar functions that will allow me to catch or not catch certain (or all) signals. Please clarify this for me, if you can. Thanks, Kevin -- To unsubscribe: mail -s unsubscribe [EMAIL PROTECTED] < /dev/null
