36Description
37===========
38
39Get and set the integer value for IR inactivity timeout.
40
41If supported by the hardware, setting it to 0  disables all hardware timeouts
42and data should be reported as soon as possible. If the exact value
43cannot be set, then the next possible value _greater_ than the
44given value should be set.
45
46.. note::
47
48   The range of supported timeout is given by :ref:`LIRC_GET_MIN_TIMEOUT`.

50Return Value
51============
52
53On success 0 is returned, on error -1 and the ``errno`` variable is set
54appropriately. The generic error codes are described at the
55:ref:`Generic Error Codes <gen-errors>` chapter.
