+**************************
+
+Name
+====
+
+LIRC_SET_REC_TIMEOUT - sets the integer value for IR inactivity timeout.
+
+Synopsis
+========
+
+.. cpp:function:: int ioctl( int fd, int request, __u32 *timeout )
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by open().
+
+``request``
+    LIRC_SET_REC_TIMEOUT
+
+``timeout``
+    Timeout, in microseconds.
+
+
+Description
+===========
+
+Sets the integer value for IR inactivity timeout.
+
+If supported by the hardware, setting it to 0  disables all hardware timeouts
+and data should be reported as soon as possible. If the exact value
+cannot be set, then the next possible value _greater_ than the
+given value should be set.
+
+.. note::
+
+   The range of supported timeout is given by :ref:`LIRC_GET_MIN_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.
