D - int86

However I couldn't get int86 to work (I have WinXP). I thought maybe I could
get it to work in D, but it didn't anyway (I did translate part of dos.h).
Any idea of how I could do it?

Maybe you are. I created dos.d with a line
extern (C) int int86(int,REGS *,REGS *);
and I previously defined REGS, but when I compile the program, I get "Error
42: Symbol Undefined _int86". The same happens when I try to compile a
similar program using dmc.

Error 42 is not a compiler error, it's a linker error. I suspect you haven't supplied the body of the function int86() to the linker.

[I admit this should've been in some c++ forum, but now that we're at it...]
Yes, my mistake: I should've said "... when I link...". int86() is declared
in dos.h, however I can't use it not even with dmc. Yes, it's right below a
"#ifndef __NT__" and I have XP, but I expected that it would be fully
supported in some library.

What memory model are you using? int86() accesses interrupts, which is not available to Win32 memory model programming.

You lost me there... hehe... I don't know, I really don't. Well, I guess
I'll leave it there.

I wanted int86() because I wanted to implement some (portable) functions for
the console. But if int86() is not available, is there any other option?

Win32 has a whole slew of functions to manipulate the console - but none of it is portable. But you can use the DMC portable shell around them, www.digitalmars.com/rtl/disp.html

No platform that D supports will ever have access to the bad-old-days DOS int86 functions. You'll have to figure out what the particular int86 function calls are supposed to do, and re-write them using standard functions.
