References in perl are a bit different from C or other languages.

What you have passed is like a scalar with the reference to an array; so the ways to retrieve it are: 


sub spawn_proc_prog {
    my ($r, $command, $argv) = @_;

    # to access the elements of $argv you do
    my $first = $argv->[0];
    my $second = $argv->[1];

    # or
    my @argv = @{$argv};

    # and there's a lot more..

Update: try perldoc perlref for more information about references in perl.

He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.
