Re^3: about THREAD SIGNALLING

[Khen1950fx]

Just remember that sub catch_CtrlC {} and SIG{'INT'} = \&catch_CtrlC; must both be included in each thread that you want to SIGINT out of.

#/usr/bin/perl

use strict;
use warnings;
use threads;
use threads::shared;

my @thrList;
my $count = 1;
share $count;

my $counter = 3;

while ($counter) {
    $counter--;
    my $thrHandle = threads->create( \&thrdfun );
    push @thrList, $thrHandle;
}

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

sub thrdfun {

    sub catch_CtrlC {
        $_->kill('TERM');
    }

    $SIG{'INT'} = \&catch_CtrlC;
    print "thrdfun: $count \n";
    $count++;
    while (1) {
        ();
    }
    exit;
}

OK, I got the point. The thread sig handler should be defined inside the thread body, different from the process signal handler.
