how to poll keyboard

[Paul Nakada]

I am in need of a way to read a terminal keyboard without
stopping if there is no keypress...  this is the scenario..

   for(ever)
	   checkkeypress();
	   dostuff according to keypress()
   endforever

what i need is to do the keyprocessing even if there is no keypress..
in essence skipping over the checkkeypress if there is no keypress...
is there any way to do this?  i have been unsuccessful in using
rawmode and curses....   can someone please enlighten me??
thanks... please respond by email...
