This question probably will require a somewhat lengthy answer.  I hope that
someone out there will take the time.

I have the SAS/C compiler for the AMIGA and I want to write a routine that
I can call that will check for a keypress.  If a key is being pressed, I want
the routine to report the key being pressed.  If not I want it to return -1
or some such thing.  Can anyone tell me how to do this (or direct me to some
source code that does this)?  I have a feeling that I'm going to have to use
the keyboard device or the input device or the console device.  If so, I'm
really going to need some help getting started.

Thanks much in advance.
