Look at
$SIG{INT)=\&catch_signal;
Sub catch_signal {
$signal=shift;
#
# do something
#
exit;
}

Subject: Re: Not catching HUP signal - Perl Sybase
Sorry for replying late...
The task that I want to achieve is to catch the HUP signal and send
notification about the process. But due to addition of sybase::ctlib
it catches the signal and my program fails.
Another issue is that sybase::ctlib is used throughout in our project
and I cannot change it just for this...
My process runs as a daemon and when it starts up it creates a file
containing pid of it. So that indicates the process is up and runing.
But when the m/c is shutdown, HUP signals are sent to all process
runinig and I want to track it and delete the pid file created. But
its not happeining....
Is there any other way to achive this....
Thanks a lot.
