  Listen, I apologize if this is sort of a beginner question. I need to
find out how to return a value from an asm procedure. I'm using o2c (the
obj to coff converter), so this is for tasm.

  Also, how do I set up the prototype in my c++ program? Can I return
structs etcetera, or only pointers to them? Here is a sample:

p386
ideal
model flat,c

extern malloc: proc

virt dd ?

public  makevirt
proc    makevirt
        push    64000
        push    0
        call    malloc
        pop     virt
        ;I want to return virt to the c++ program
        ret
endp    makevirt
end

/* C++ program */

void main ()
{ unsigned char * virtscreen = makevirt ();
}


So my question is, what do I add to make this compile?

All help greatly appreciated,
