91 <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> the driver returns the
100 <constant>VIDIOC_QUERYMENU</constant> ioctl with a pointer to this
104 by calling <constant>VIDIOC_QUERYMENU</constant> with successive
108 for <constant>VIDIOC_QUERYMENU</constant> to return an &EINVAL; for some
145 bound for <constant>V4L2_CTRL_TYPE_INTEGER</constant> controls and the
146 lowest valid index for <constant>V4L2_CTRL_TYPE_MENU</constant> controls.
147 For <constant>V4L2_CTRL_TYPE_STRING</constant> controls the minimum value
150 <constant>V4L2_CTRL_TYPE_INTEGER64</constant> controls. Note that this is a
157 bound for <constant>V4L2_CTRL_TYPE_INTEGER</constant> controls and the
