Arguments
``fd``
File descriptor returned by :ref:`open() <func-open>`.
-``request``
- VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL
-
``argp``
To enumerate frame intervals applications initialize the ``index``,
``pad``, ``which``, ``code``, ``width`` and ``height`` fields of struct
-:ref:`v4l2_subdev_frame_interval_enum <v4l2-subdev-frame-interval-enum>`
+:c:type:`v4l2_subdev_frame_interval_enum`
and call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL` ioctl with a pointer
to this structure. Drivers fill the rest of the structure or return an
EINVAL error code if one of the input fields is invalid. All frame
implemented it on a single pad only. Its behaviour when supported on
multiple pads of the same sub-device is not defined.

EINVAL
The struct
- :ref:`v4l2_subdev_frame_interval_enum <v4l2-subdev-frame-interval-enum>`
+ :c:type:`v4l2_subdev_frame_interval_enum`
``pad`` references a non-existing pad, one of the ``code``,
``width`` or ``height`` fields are invalid for the given pad or the
``index`` field is out of bounds.
