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