Arguments
``fd``
File descriptor returned by :ref:`open() <func-open>`.
-``request``
- VIDIOC_SUBDEV_ENUM_MBUS_CODE
-
``argp``
To enumerate media bus formats available at a given sub-device pad
applications initialize the ``pad``, ``which`` and ``index`` fields of
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_MBUS_CODE` ioctl with a pointer to this
structure. Drivers fill the rest of the structure or return an ``EINVAL``
error code if either the ``pad`` or ``index`` are invalid. All media bus
information about the try formats.

The struct
- :ref:`v4l2_subdev_mbus_code_enum <v4l2-subdev-mbus-code-enum>`
+ :c:type:`v4l2_subdev_mbus_code_enum`
``pad`` references a non-existing pad, or the ``index`` field is out
of bounds.
