IAudioEndpoint::GetLatency method (audioengineendpoint.h)
The GetLatency method gets the latency of the audio endpoint.
Syntax
HRESULT GetLatency(
[out] HNSTIME *pLatency
);
Parameters
[out] pLatency
A pointer to an HNSTIME variable that receives the latency that is added to the stream by the audio endpoint.
Return value
If the method succeeds, it returns S_OK.
Remarks
There is some latency for an endpoint so that the buffer can stay ahead of the data already committed for input/output (I/O) transfer (playback or capture). For example, if an audio endpoint is using 5-millisecond buffers to stay ahead of the I/O transfer, the latency returned by this method is 5 milliseconds.
This method must not be called from a real-time processing thread.
The Remote Desktop Services AudioEndpoint API is for use in Remote Desktop scenarios; it is not for client applications.
