You can do non-blocking reads by using fcntl (in reference manual sections
2 and 7) do set the O_NDELAY status flag. Or you can open a file with
O_NDELAY set if you aren't using stdin. I should warn you that if your
program dies or absent-mindedly quits with O_NDELAY set for stdin, then
the shell will mistake the return without delay for an EOF and log you off
immediately.
