SetInputLatency
Sets the input latency of the clock device.
Declaration
kern_return_t SetInputLatency(uint32_t in_latency);Parameters
- in_latency:
The input latency value to set.
Return Value
kIOReturnSuccess on success, or another value if an error occurs. For a list of error codes, see Error Codes.
Discussion
Drivers can change the input latency of the clock device dynamically. If successful, changing the available input latency sends a notification to the host to update the object state.
This method synchronizes by using the work queue created by the object.
