@deftypefun int rl_timeout_remaining (unsigned int *secs, unsigned int *usecs)
Return the number of seconds and microseconds remaining in the current
timeout duration in @code{*secs} and @code{*usecs}, respectively.
Returns -1 on error or when there is no timeout set, 0 when the timeout has
expired (leaving @code{*secs} and @code{*usecs} unchanged), and 1 if the
timeout has not expired. If @code{secs} and @code{usecs} are @code{NULL},
timeout duration in @var{*secs} and @var{*usecs}, respectively.
Both @var{*secs} and @var{*usecs} must be non-NULL to return any values.
The return value is -1 on error or when there is no timeout set,
0 when the timeout has expired (leaving @var{*secs} and @var{*usecs}
unchanged),
and 1 if the timeout has not expired.
If either of @var{secs} and @var{usecs} is @code{NULL},
the return value indicates whether the timeout has expired.
