Hi
Is there a way to call exported methods from a DLL without using win32::API.
Has anyone tried calling an exported function from C DLL in a Perl Program
using XS.
I have a C DLL's source file and its header file
and using h2xs
D:\DLLProjects\simpledll3>h2xs -n ext2 simpledll3.h
Writing ext2/ext2.pm
Writing ext2/ext2.xs
Writing ext2/Makefile.PL
Writing ext2/README
Writing ext2/test.pl
Writing ext2/Changes
Writing ext2/MANIFEST
D:\DLLProjects\simpledll3>cd ext2
D:\DLLProjects\simpledll3\ext2>perl makefile.pl
Checking if your kit is complete...
Looks good

Stop.
where num is the exported method which I have written in teh file
SimpleDLL3.cpp
int _stdcall num(int x) {
return x+1;
}
I have written the XSUB in ext2.xs file as shown below:
int
num(x)
int x
Why does it give an error for _num or for that matter any exported function
name.
Any help would be greatly appreciated.
Thanks,
Sam.
