Hello,
having trouble with custom signal handlers.
In my code I have:
sub handleSigs {
my ($signalReceived) = @_;
my $exitVal = 0;
log_terminal("warning: received $signalReceived signal");
if ($signalReceived eq "INT") { $exitVal = 1; }
elsif ($signalReceived eq "USR1") { $exitVal = 2; }
elsif ($signalReceived eq "USR2") { $exitVal = 3; }
myExit($exitVal);
}
$SIG{USR1}=\&handleSigs;
$SIG{USR2}=\&handleSigs;
The application talks to a custom telnet server, waiting for messages and processing those messages.
If I send a SIGUSR1 to my process I get this error message:
Signal SIGUSR1 received, but no signal handler set.
How best to debug this situation?
PS: I read about safe/unsafe signals but the error message I got does not seem to apply unless I miss something.
Using perl v5.20.2 on linux debian.
Thanks.
