Re^2: calling a function from a dll

Am I perhaps calling the function wrong or something? as I get a
Not a CODE reference at xx.pl line 14
which is where the $function is called in the sub routine

#!/usr/bin/perl 
use Win32::API;  

my $function = Win32::API->new('C:\XYZClientLibrary\x86\XYZClientLibra
+ry.dll', 'XYZDecrypt', 'PPP', 'I');

print call_function('9','8B3A06617FEC4276A5711FBA4861B467', '[000001]C
+0808FC9B3062D91E7B9B1D9A7B79216');

sub call_function {
    my ($value, $key, $encrypted) = @_;
    # Here we pad $value to the expected length, to avoid a buffer ove
+rrun
    # I guess that the result is at most as long as the encrypted stri
+ng
    $value = ' ' x length($encrypted);
    print (" $value, $key, $encrypted\n");
    $value = $function->( $value, $key, $encrypted );
    $value =~ s!\0.*!!; # we assume that the first \0 returned indicat

    return $value
};
