SetClockAlgorithm
Sets the algorithm for the video clock device.
Declaration
kern_return_t SetClockAlgorithm(IOUserVideoClockAlgorithm in_clock_algorithm);Parameters
- in_clock_algorithm:
The IOUserVideoClockAlgorithm value to set.
Return Value
A kern_return_t value indicating success or failure.
Discussion
Drivers can change the clock algorithm of the clock device dynamically. If successful, the clock device sends a notification to the host to update the object state.
