Subject: Question about Linux signal handling
Date: Sat, 22 Feb 2003 20:45:20 -0800 (PST)	[thread overview]
Message-ID: <20030223044520.87268.qmail@web9804.mail.yahoo.com> (raw)

If I catch a signal (SIGUSR2) using "sigaction" call
then is the signal handler replaced with default
handling, if I don't install the signal handler again?

I remember that in UNIX "signal" system call default
signal bahavior was to replace the signal handler with
default after everytime signal was received?

My observation is that even if I get same signal
twice, I get the same print (which I have in my signal
handler) again, illustrating that signal handler was
not replaced with default !!! Is that the correct
behavior of "sigaction"?

Thanks,
Tom
