This option is only effective if @code{read} is reading input from a
terminal, pipe, or other special file; it has no effect when reading
from regular files.
If @var{timeout} is 0, @code{read} returns success if input is available on
the specified file descriptor, failure otherwise.
If @var{timeout} is 0, @code{read} returns immediately, without trying to
read and data. The exit status is 0 if input is available on
the specified file descriptor, non-zero otherwise.
The exit status is greater than 128 if the timeout is exceeded.
