Synopsis ======== .. c:function:: int ioctl( int fd, LIRC_GET_MIN_TIMEOUT, __u32 *timeout) :name: LIRC_GET_MIN_TIMEOUT .. c:function:: int ioctl( int fd, LIRC_GET_MAX_TIMEOUT, __u32 *timeout) :name: LIRC_GET_MAX_TIMEOUT Arguments ========= ``fd`` File descriptor returned by open(). ``timeout`` Timeout, in microseconds. Description =========== 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 ` chapter.
