autowrapping function declarations: compiler directives and calling conventions

[Garrett Goebel]

[warning C novice here]

I've been playing with typemap. Hoping I could create a typemap that would
allow me to access functions from the Win32API using ENABLE => AUTOWRAP for
function declarations.

Most Win32 api functions use pascal calling conventions. For instance, in
winuser.h the function declaration for MessageBoxA is:

WINUSERAPI
int
WINAPI
MessageBoxA(
    HWND hWnd ,
    LPCSTR lpText,
    LPCSTR lpCaption,
    UINT uType);

might translate roughly to:

__declspec(dllexport)
int
__pascal
MessageBoxA(
    long hWnd ,
    char* lpText,
    char* lpCaption,
    int uType);


Using a typemap file containing:
HWND            T_LONG
LPCSTR          T_PV
UINT            T_UV

I can get the following function definition to work:

int Message_Box_A(
    HWND hWnd,
    LPCSTR lpText,
    LPCSTR lpCaption,
    UINT uType) {
  printf("%d, %s, %s, %d\n", hWnd, lpText, lpCaption, uType);
  return 1;
}


But the compiler directives are throwing me when it comes to enabling
autowrapping function declarations.

use Inline C => Config => ENABLE => AUTOWRAP 
             => LIBS => '-luser32' 
             => TYPEMAPS => './typemap';
use Inline C => DATA;
MessageBoxA(0, "text", "caption", 0);
__END__
__C__
#include <windows.h>

???


Is it possible to autowrap functions with different calling conventions? If
so, what do I need to provide to make it work?
