The ioctl DMX_GET_EVENT has never been implemented. I guess no software is using it because of its lack of implementation. Future software won't use it, too, because this API doesn't make much sense the way it is: Frontend events have their own different API. Scrambling events can't be generated in a useful way by the hardware I know of. Signed-off-by: Andreas Oberritter <obi@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
