There isn't any portable way of doing it in C, because some of the
operating systems C is available on cannot do it.  The best you can do
is make up two names (kb_getch, kb_ready, perhaps) and write an
implementation for each of the systems you are concerned with.

Perhaps it is time the net collaborated to produce model implementations
of these functions for MS-DOS, OS/2, VMS, BSD, S5, put them on a mail
server somewhere, and added the location to the FAQ?
