A Dv4l2-event.rst7 The driver must use :c:type:`v4l2_fh` to be able to support V4L2 events.

36 list of the :c:type:`v4l2_fh` struct so :ref:`VIDIOC_DQEVENT` will

A 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

790 v4l2_fh 的用户（位于 V4l2 框架中，并非驱动）可通过测试

844 以下是 v4l2_fh 函数使用的简介：
851 void v4l2_fh_add(struct v4l2_fh *fh)
863 清理文件句柄。在清理完 v4l2_fh 后，相关内存会被释放。
866 如果 v4l2_fh 不是嵌入在其他结构体中的，则可以用这些辅助函数：
876 v4l2_fh 并释放空间。
