StopIO
Tells the clock device to stop IO.
Declaration
virtual kern_return_t StopIO(IOUserVideoStartStopFlags in_flags);Parameters
- in_flags:
IOUserVideoStartStopFlags to indicate how IO is stopping.
Discussion
The default implementation always returns kIOReturnSuccess. Subclass and override this method to handle any hardware specific things when IO is stopping, then call the superclass implementation to update IO state.
