ioctl parameters

[Esa Ikonen <esa.ikonen@xxxxxx>]

Hi! Could someone help a newcomer a little bit?

The parameters of ioctl calls are unclear to me. For excample in
	ioctl ( xxx, VIDIOC_QUERYCAP, yyy);
What is the meaning of parameters xxx and yyy? I guess that xxx is a
pointer to struct v4l2_capability, but what is yyy?

Where could I read more about the subject?
