Ok, I know this sounds stupid. However:

I have been looking, for ages, for a way of doing a non-waiting getchar.

Normally, getchar() waits until you give it a carriage return. If you are
in cbreak/raw mode (or something equivalent) it waits until you hit a
key. Is there any portable call (i.e., one that can be expected to work
on most computers, without hardware hacks) that will return *whether or not*
you have hit a key, and return a meaningful value? I would like to have such
a routine so I can check to see what the user wants to do without halting
my program. How is this done, pray tell?
