Dequeue an array in perl with thread::queue

Question

I am trying to process data with a set of threads and enqueue it with another, currently the enqueueing and dequeueing process doesn't seem to be working

Any thoughs??

sub process() {
    while (my @DataElement = $DataQueue->dequeue()) {
        print "\t".$DataElement[0]."\n";
    }
}

I use the following to enqueue the data

my @l;
push(@l, $directories.$suffix);
push(@l, "testclass");
push(@l, $eachFile);
$DataQueue->enqueue(\@l);

Answer 1

Are you accessing an array reference without dereferencing it? Try

while (my $DataElementRef = $DataQueue->dequeue()) {
    my @DataElement = @$DataElementRef;
    print "\t".$DataElement[0]."\n";
}

@l is not shared, so you can't pass it's reference to another thread. Use threads::shared.
