Re: CTRL+C Handling in Perl Threads

[remiah]

If you have this trouble on windows, Please refer ctrl + c on Win32 (signal handling). Regards.

I am using this in Linux/Unix. So Windows is not an issue for me. Can you help me in Unix. Here is my updated sample code:

use strict;
use threads;
no warnings 'threads';

our @ThreadsArr;

$SIG{INT} = \&INT_HANDLER;

$| = 1;

sub INT_HANDLER {
    print "Received Interrupt. Stopping Main Program\n";
}


for (my $ii = 0; $ii < 10; $ii++) {
    my $Thread = threads->new( "Thread_SUB", $ii );
    push (@ThreadsArr, $Thread);
}

foreach (@ThreadsArr) {
    $_->join();
}

sub Thread_SUB {
    my $thread_id = shift;
    $SIG{'KILL'} = sub {
        print "Killing Thread $thread_id\n";
        threads->exit();
    };
    for (my $ii = 0; $ii <= 15; $ii++) {
        print "$thread_id - Sleeping $ii\n";
        sleep 1;
    }
}

This program is not acknowledging the interrupts when sent as ctrl+c

I am working on FreeBSD.

First example showed me SIG_INT message with correcting a few typo. This time also shows me message like

0 - Sleeping 14
^CReceived Interrupt. Stopping Main Program   <==pressed ctrl+c

I wonder why?

Could you send SIG INT from another terminal? I mean by kill command.
