[Dev-C++] assembly (not inline!)

[Marco R. <ma...@ne...>]

Hello all,

 

I wish to know if is there a way to make a function in assembly, compile it
in masm and then use it in c++. I search the web but found nothing about it.
My idea is something like linking the masm result with my c++ program.

 

Tanks in advance

 

Marco.

Have you looked at http://www.masm32.com/ ?

A would guess that masm produces a normal object file. Just declare the f=
unction
as extern C to avoid problem with name-mangling.

Hmm... need to try it before saying too much...

downloading masm32...

(some sounds of your choice to illustrate work)

Results:

I tried this simple example:


.386
.model flat,stdcall
option casemap:none

include \masm32\include\windows.inc

.code
asmfunc proc inp:UINT
   mov eax, (inp)
   add eax, 10

   ret

asmfunc endp

end


linked the resulting .obj (project->project options, parameters add libra=
ry or
object) with the following:

#include <iostream>
#include <stdlib.h>

extern "C" int asmfunc(int);


using namespace std;

int main(int argc, char *argv[])
{
 =20
  int x =3D 15;=20
  x =3D asmfunc(x);=09
 =20
  cout << x << endl;
 =20
  system("PAUSE");=09
  return 0;
}


I do get a linker warning, but it does work.


So, I guess the answer is yes...

Check out vesa graphics - a bios extension to control high-resolution
graphics. I would actually recommend that you use the djgpp compiler
instead of mingw. djgpp is also a gcc port, but building dos applications
with dos-extender to support much memory and protected mode.

Scan through the following links:
