Help on Win32 API

Hi,

I have a dll by name AduHid.dll.
There is a function with prototype

void * _stdcall OpenAduDeviceBySerialNumber(const char*
psSerialNUmber,unsigned long iTimeout);

I used the following perl code to call the above function

use Win32::API;
my $function = Win32::API->new(
'AduHid.dll','int OpenAduDeviceBySerialNumber(const
char* psSerialNUmber,unsigned long iTimeout)' );

my $return = $function->Call("A03744",0);

But i get an error
1. unknown parameter type const and unsigned
2. Argument A03744 isnt numeric in subroutine entry.

I tried removing const and unsigned.Then I got an error
"Modification of read only value attempted".

Where am i going wrong?
Please advise.

regards,
jis
