^CSIGINT handler "my_handler" not defined. Sigtrap is not able to find handler function.

girijaj has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, Anyone could explain why my sigtrap is not able to see handler function? I am getting "^CSIGINT handler "my_handler" not defined." error.

use sigtrap 'handler' => \&my_handler, 'normal-signals';

and I have declared my_handler as:

sub my_handler {
  die "Caught signal $! \n";
}

Is that a typo? You use `my_handler` and `my_hanlder`. `use sigtrap 'handler' => \&my_handler, 'normal-signals'; sub my_hanlder { die "Caught signal $! \n"; }` [download]	[reply] [d/l] [select]

Thanks for the response. yes it was typo, i fixed it. I think its a scope of my program. Somehow I have to make this handler function visible to sigtrap. But I am not getting it how to do that.	[reply]

You need to provide more context if you want help but reduce it down to a minimal example that still does not work. Here's my minimal yet working example: `#!/bin/env perl use strict; use warnings; use sigtrap 'handler' => \&my_handler, 'normal-signals'; while ( 1 ) { print "running...\n"; sleep 30; } sub my_handler { die "Caught signal $!\n"; }` [download]	[reply] [d/l]
