+Synopsis

+
+.. cpp:function:: int ioctl( int fd, int request = DMX_GET_EVENT, struct dmx_event *ev)
+
+
+Arguments
+---------
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  int fd
+
+       -  File descriptor returned by a previous call to open().
+
+    -  .. row 2
+
+       -  int request
+
+       -  Equals DMX_GET_EVENT for this command.
+
+    -  .. row 3
+
+       -  struct dmx_event \*ev
+
+       -  Pointer to the location where the event is to be stored.
+
+
+Description
+-----------
+
+This ioctl call returns an event if available. If an event is not
+available, the behavior depends on whether the device is in blocking or
+non-blocking mode. In the latter case, the call fails immediately with
+errno set to ``EWOULDBLOCK``. In the former case, the call blocks until an
+event becomes available.
+
+
+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.

+    :header-rows:  0
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  ``EWOULDBLOCK``
+
+       -  There is no event pending, and the device is in non-blocking mode.
