-    <para>This ioctl is part of the <link linkend="mmap">memory
-mapping</link> I/O method. It can be used to query the status of a
-buffer at any time after buffers have been allocated with the
-&VIDIOC-REQBUFS; ioctl.</para>
-
-    <para>Applications set the <structfield>type</structfield> field
-    of a &v4l2-buffer; to the same buffer type as was previously used with
-&v4l2-format; <structfield>type</structfield> and &v4l2-requestbuffers;
-<structfield>type</structfield>, and the <structfield>index</structfield>
-    field. Valid index numbers range from zero
-to the number of buffers allocated with &VIDIOC-REQBUFS;
-    (&v4l2-requestbuffers; <structfield>count</structfield>) minus one.
-The <structfield>reserved</structfield> field should to set to 0.
-When using the <link linkend="planar-apis">multi-planar API</link>, the
-<structfield>m.planes</structfield> field must contain a userspace pointer to an
-array of &v4l2-plane; and the <structfield>length</structfield> field has
-to be set to the number of elements in that array.
-After calling <constant>VIDIOC_QUERYBUF</constant> with a pointer to
-    this structure drivers return an error code or fill the rest of
-the structure.</para>
-
-    <para>In the <structfield>flags</structfield> field the
-<constant>V4L2_BUF_FLAG_MAPPED</constant>,
-<constant>V4L2_BUF_FLAG_QUEUED</constant> and
-<constant>V4L2_BUF_FLAG_DONE</constant> flags will be valid. The
-<structfield>memory</structfield> field will be set to the current
-I/O method. For the single-planar API, the <structfield>m.offset</structfield>
-contains the offset of the buffer from the start of the device memory,
-the <structfield>length</structfield> field its size. For the multi-planar API,
-fields <structfield>m.mem_offset</structfield> and
-<structfield>length</structfield> in the <structfield>m.planes</structfield>
-array elements will be used instead. The driver may or may not set the remaining
-fields and flags, they are meaningless in this context.</para>
