Any thoughts on following code?
Hello all,
I want to catch SIGSEGV signal, do some processing and after that want to
call default SIGSEGV handler.
I was not getting how to call default SIGSEGV handler. Following code
snippet is the work around I'm using.
Let me know if anything wrong in this code or your thaughts on this.
local $SIG{SEGV} = \&seg_handler;
our $sig=0;
sub seg_handler
{
my $sig = shift;
print "seg_handler :: Caught $sig \n";
$SIG{$sig} ='DEFAULT';
print "Sending $sig signale to proc $$\n";
kill $sig,$$;
}
until ($sig) {
print "running...\n";
sleep 1;
}

Hello Gurus,
I'm using following code snipet to catch SIGSEV signal.
local $SIG{SEGV} = \&seg_handler;
sub seg_handler
{
my $sig = shift;
print "seg_handler :: Caught $sig \n";
}
while (1)
{
print ("Still alive \n");
sleep 1;
}
When I send SEGV signal to this process (kill -11 proc_id) from command
promt, I'm able to catch this signal.
I need to call default SEGV signal handler after my processing.
How should I code for this?
Thanks in advance.
