Name

DMX_GET_EVENT

Synopsis

--------

.. c:function:: int ioctl( int fd, DMX_GET_EVENT, struct dmx_event *ev)

    :name: DMX_GET_EVENT

Arguments

---------

``fd``

    File descriptor returned by :c:func:`open() <dvb-dmx-open>`.

``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.

    -  .. row 1

       -  ``EWOULDBLOCK``

       -  There is no event pending, and the device is in non-blocking mode.
