Hi monks! i'm trying to communicate with a DLL I have and pass two string variables to it, and get back a double. It isn't returning anything. There are no errors during debugging, but $prwin gets calle. I used the example from cpan. Any help would be greatly appreciated. Here part of my pl file: 
use Win32::API;

sub pl_prwin
{
    my $prwin;
    my $hands;
    my $board;
    my $GetPrwin;
    my $lpBuffer;
    my $return;
    
    $hands = "AhKh|Td9s|QQ+,AQs+,AQo+|JJ-88|XxXx|XxXx|XxXx";
    $board = "Ks7d4d";
    
    $GetPrwin = new Win32::API(
        "OH-DLL.dll", "prwin1($hands, $board)", 'PP', 'N');
    
    $lpBuffer = " " x 80;
    $return = $GetPrwin->Call(80, $lpBuffer);
    $lpBuffer =~ s/\0.*$//;
    $prwin  = $lpBuffer;
    
    return $prwin;
}
