9 struct v4l2_fh is allocated in the driver's ``open()`` file operation handler.
11 :c:type:`v4l2_fh` must be initialized with a call to :c:func:`v4l2_fh_init`,
13 :c:type:`v4l2_fh` with the :c:type:`file` by setting ``file->private_data`` to
14 point to the :c:type:`v4l2_fh`.
16 Similarly, the struct v4l2_fh is freed in the driver's ``release()`` file
22 :c:type:`v4l2_fh` associated with a :c:type:`file` by calling
32 struct v4l2_fh fh;
59 struct v4l2_fh *fh = file_to_v4l2_fh(file);
69 Below is a short description of the :c:type:`v4l2_fh` functions used:
