You can download Allegro, an excellent graphics-sound-and-the-kitchen-
sink library which also features keyboard-handling routines. In your
program you can install the Allegro keyboard handler, and then use it in
two ways: with a buffer-type system, a la int 16h, or merely by checking
whether a certain key is pressed or released. (With this second method
you can detect multiple keypresses.) You don't have to know any of the
intimate details, although as always it wouldn't hurt :-)

You can download Allegro from:
