Welcome to the forum.

Here is a quick example :

#include <stdio.h>

extern int __stdcall testproc(int x, int y);

int main(int argc,char *argv[])
{
int x=125,y=75;
printf("125 + 75 = %d",testproc(x,y));
return 0;
}


.386
.model flat,stdcall
option casemap:none

.code

testproc PROC x:DWORD,y:DWORD

mov eax,x
add eax,y
ret

testproc ENDP


thank you Vortex for your help and your example
now understand how do i do it :)
