Arguments
``fd``
File descriptor returned by :ref:`open() <func-open>`.

``argp``
To enumerate frame sizes applications initialize the ``pad``, ``which``
, ``code`` and ``index`` fields of the struct
-:ref:`v4l2_subdev_mbus_code_enum <v4l2-subdev-mbus-code-enum>` and
+:c:type:`v4l2_subdev_mbus_code_enum` and
call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_SIZE` ioctl with a pointer to the
structure. Drivers fill the minimum and maximum frame sizes or return an
EINVAL error code if one of the input parameters is invalid.
