- in_driver:
The video driver that owns this object.
- in_is_settable:
A Boolean value that indicates whether the control value can be set.
- in_control_value:
A Boolean value for the control’s current value.
- in_control_element:

Return Value
The control, if it was successfully allocated and initialized.
Discussion
If you subclass IOUserVideoBooleanControl to override behavior, don’t use this method to allocate or initialize the custom subclass.
