Dv4l2-fh.rst4 struct :c:type:`v4l2_fh` provides a way to easily keep file handle specific
8 New drivers must use struct :c:type:`v4l2_fh`
12 The users of :c:type:`v4l2_fh` (in the V4L2 framework, not the driver) know
13 whether a driver uses :c:type:`v4l2_fh` as its ``file->private_data`` pointer
17 struct :c:type:`v4l2_fh` is allocated as a part of the driver's own file handle
21 In many cases the struct :c:type:`v4l2_fh` will be embedded in a larger
36 struct v4l2_fh fh;
64 struct v4l2_fh *fh = file->private_data;
74 Below is a short description of the :c:type:`v4l2_fh` functions used:

Dv4l2-event.rst6 The driver must use :c:type:`v4l2_fh` to be able to support V4L2 events.
13 The :c:type:`v4l2_fh` struct has a list of subscribed events on its
17 struct is added to :c:type:`v4l2_fh`\ ``.subscribed``, one for every
35 list of the :c:type:`v4l2_fh` struct so :ref:`VIDIOC_DQEVENT` will
46 - struct :c:type:`v4l2_fh` has two lists: one of the ``subscribed`` events,

Dv4l2-framework.txt86 结构体保存 V4L2 设备节点的数据；将来 v4l2_fh 结构体将跟踪文件句柄
783 v4l2_fh 结构体
786 v4l2_fh 结构体提供一个保存用于 V4L2 框架的文件句柄特定数据的简单方法。
788 必须使用 v4l2_fh 结构体，因为它也用于实现优先级处理（VIDIOC_G/S_PRIORITY）。
790 v4l2_fh 的用户（位于 V4l2 框架中，并非驱动）可通过测试
792 v4l2_fh 作为他的 file->private_data 指针。这个位会在调用 v4l2_fh_init()
795 v4l2_fh 结构体作为驱动自身文件句柄结构体的一部分被分配，且驱动在
798 在许多情况下，v4l2_fh 结构体会嵌入到一个更大的结构体中。这钟情况下，
