ASM Community

Hello. I got an asm function. I did with RADASM and MASM32. It generated an obj file.

On Devc++ (my Ide) I included the obj file. in project options

But I dont know what should I put on this .h file and then how to call it from the main.c

I did this but I am not sure.

float MyProc(float var1, float var2);


This is my assembly function

.386 
.model flat, stdcall
option casemap:none



.data


.code

Myproc proc var1:REAL4, var2:REAL4
    LOCAL retval:REAL4
    finit
    fld var1
    fld var2

    fadd
    fstp retval
    fwait                ;<- is this really needed?
    mov eax, retval
    ret
Myproc endp


end;

I did this on my C program

#include "H:\Practica Arquitectura del Computador\include\flotantes.h"


float MyProc(float, float);

void sum(void)
{
     float total2;
     total2 = MyProc(3.2, 4.2);
     printf("Total is: %d", total2);
}

But I get an error

  undefined reference to `MyProc'


my .h file is this

#ifndef _FLOTANTE_H
#define _FLOTANTE_H


float MyProc(float var1, float var2);


#endif
