    Okay, this is going to be an unorthodox answer, but it may get you where
    you need to go...

    If your program is only going to run on PC's, you can always go to the
    BIOS memory. I can't remember the exact address (though I'll look it up
    when I get home, if you like) but the BIOS has a keyboard buffer and two
    pointers. When I was writing a video game way back in '91-'92, we took
    control of the buffer and buffer pointers with C pointers, and it worked
    great!

    Of course, you'd have no portability....
