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