Re: Perl threads - capturing value returned from sub

Cancel this one; I found the answer, which was to just assign a
variable to the join:

my $result = $t->join;

Seems like I always have a breakthrough immediately after I post to
this site! :)

Just to amplify slightly, you can return arrays too.
#!/usr/bin/perl
use warnings;
use strict;
use threads;
use threads::shared;

# join() does three things: it waits for a thread to exit,
# cleans up after it, and returns any data the thread may
# have produced.

my $thr = threads->new(\&sub1);

my $return = $thr->join;

print "Thread returned @$return\n";

#hold for key input
<>;
##########################################################
sub sub1 {
my @values = ('1',2, 'ten');
print "@values\n";

while(1){sleep 1}

return \@values;
}

__END__
