G'day.
I've just stepped into the, erm, wonderful world of Win32 programming. I have a dll which is needed to translate a password in an application we use. I've been given the specs of the dll as follows:

Function: bgfnTextDecrypt
    Description:
    Export Ordinal: 0
    Returns
        Boolean: BOOL
    Parameters
        String: LPSTR
        Receive String: LPSTR

[download]
I'm trying to translate this into either a Win32::API or Win32::API::Prototype programme.
I have tried the following pieces of code:
#!perl
use strict;
use Win32::API;

my $bgfnTextDecrypt = new Win32::API('eq_handy', 'bgfnTextDecrypt','PP
+','P');
if(not defined $bgfnTextDecrypt) {
    die "Can't import API bgfnTextDecrypt: $!\n";
    }
print "Eerk\n";
my $lpBuffer = " " x 80;
print "Eerk2\n";
my $return = $bgfnTextDecrypt->Call('password-crypt', $lpBuffer);
print "Eerk3\n";
my $decrypt = substr($lpBuffer, 0, $return);
print "$decrypt\n";

[download]
and 
#!perl
use strict;
use Win32::API::Prototype;
ApiLink( 'eq_handy.dll', 'BOOL bgfnTextDecrypt( LPSTRING  lpString, LP
+STRING, lpBuffer )' ) || die;
my $lpString="password-crypt";
my $lpBuffer = pack( "L*", $lpString);
    
bgfnTextDecrypt($lpString);
    
my $pass = unpack( "L*", $lpBuffer );
print( "The pass is: $pass\n";

As I have never coded in Win32 before, I'm a little lost.
Is there anyone who can point me in the right direction? Even a similar MS dll as an example would be wonderful.

Thanks.
Neil

EDIT: Changed the dll name in the second example.
