| H A D | v4l2-fh.rst | 6 struct v4l2_fh provides a way to easily keep file handle specific
10 New drivers must use struct v4l2_fh
14 The users of :c:type:`v4l2_fh` (in the V4L2 framework, not the driver) know
15 whether a driver uses :c:type:`v4l2_fh` as its ``file->private_data`` pointer
19 struct v4l2_fh is allocated as a part of the driver's own file handle
23 In many cases the struct v4l2_fh will be embedded in a larger
38 struct v4l2_fh fh;
66 struct v4l2_fh *fh = file->private_data;
76 Below is a short description of the :c:type:`v4l2_fh` functions used:
