input ready under UNIX ??!!??

[William E. Davidsen Jr]

Once upon a time I did this, but the source code is hiding...

The basic technique is to set the input stream nonblocking and do a read
of one char. If you don't get it, kbhit returns zero. If you do, push
back the character (with ungetc as I recall) and return one. In any case
restore the original state of the stream. On SysV you can play with the
wait time, etc, to produce a function which provides "if kbhit in N
secs" if it's useful.

Wish I could find or remember more of the details, but this should give
you a start on a solution.
