Hi,

As regards Inline::C, you have: 
use strict;
use warnings;
use Inline C => Config =>
MYEXTLIB  => 'd:\path\to\CrappyLibrary.dll',
INC => '-Id:\path\to',
BUILD_NOISY => 1;

use Inline C => 'DATA';

my $result = RegisterClient2($client_id, $S{read_IP});

__DATA__
__C__
#include "Easy4ApiDef.h"

 I think you've *nearly* nailed it. To make it work you could probably invoke the help of the 'autowrap' config option ... see the Inline::C docs (I'm not really up to speed with this aspect of Inline::C).

Instead, I would probably do the wrapping myself. Something like: 
use strict;
use warnings;
use Inline C => Config =>
MYEXTLIB  => 'd:\path\to\CrappyLibrary.dll',
INC => '-Id:\path\to',
BUILD_NOISY => 1;

use Inline C => 'DATA';

my $client_id = 5; #numeric
my $read_IP = 'whatever'; #string
my $result = wrap_RegisterClient2($client_id, $S{read_IP});

__DATA__
__C__
#include "Easy4ApiDef.h"

int wrap_RegisterClient2(int cl_id, char* read_ip) {
  return RegisterClient2(cl_id, read_ip);
}

This should work ok with the gcc compiler (no hope at all with M$ compilers, as they can't link to dll's).

Update: And now ... let's check out yesterday's news ...

Cheers,
Rob
