Non-destructive read of keyboard buffer

[jit at slic.cellbio.duke.edu]

Hi, I am trying to find out if a keyboard buffer is empty but not reading
it because I don't want to get stuck if there isn't any buffered.
(on ATT SVR3)

Is there a 'standard' way on unix to do this ?

(I am currently reading using non-canonical mode with vmin=0, then
ungetc if there is any.  Hopefully there is an easier way.)

Thanks in advance.
