CVDisplayLink and CVBase only.Expand description
Retrieves the nominal latency of a CVDisplayLink.
This call allows one to retrieve the device’s built in output latency. An NTSC device with one frame of latency might report back 1001/30000 or 2002/60000, for example.
Parameter displayLink: The CVDisplayLink to get the latency period from.
Returns: A CVTime struct that holds the latency. This value may be indefinite.
