19 .. cpp:function:: int ioctl( int fd, int request, __u32 *timeout)
25 File descriptor returned by open().
28 LIRC_GET_MIN_TIMEOUT or LIRC_GET_MAX_TIMEOUT
31 Timeout, in microseconds.
37 Some devices have internal timers that can be used to detect when
38 there's no IR activity for a long time. This can help lircd in
39 detecting that a IR signal is finished and can speed up the decoding
40 process. Returns an integer value with the minimum/maximum timeout
45 Some devices have a fixed timeout, in that case
46 both ioctls will return the same value even though the timeout
47 cannot be changed via :ref:`LIRC_SET_REC_TIMEOUT`.
53 On success 0 is returned, on error -1 and the ``errno`` variable is set
54 appropriately. The generic error codes are described at the
55 :ref:`Generic Error Codes <gen-errors>` chapter.
