What outcome are you trying to get at, what device are you using and
what driver are you using with that device?

If it is a USB V4L1 device, and you are using cuse4bsd/webcamd, you
will need a very recent version of cuse4bsd to translate v4l2 ioctls
into v4l1 ioctls that your device will understand.
