IAudioInputEndpointRT::ReleaseInputDataPointer method (audioengineendpoint.h)
The ReleaseInputDataPointer method releases the acquired data pointer.
Syntax
void ReleaseInputDataPointer(
[in] UINT32 u32FrameCount,
[in] UINT_PTR pDataPointer
);
Parameters
[in] u32FrameCount
The number of frames that have been consumed by the audio engine. This count might not be the same as the value returned by the IAudioInputEndpointRT::GetInputDataPointer method in the pConnectionProperty->u32ValidFrameCount member.
[in] pDataPointer
The pointer to the buffer retrieved by the GetInputDataPointer method received in the pConnectionProperty->pBuffer member.
Return value
None
Remarks
ReleaseInputDataPointer notifies the endpoint that the audio engine no longer requires the input data pointer and also indicates the number of frames used during the session. For example, an endpoint, which represents a looped buffer, is connected to the input of the audio engine and can advance its read pointer by using the actual frame count. If u32FrameCount is zero, this indicates that the client did not use any data from the specified input buffer. The u32FrameCount must be less than or equal to the maximum frame count supported by the endpoint. To get the supported number of frames, the audio engine calls the IAudioEndpoint::GetFramesPerPacket method.
This method can be called from a real-time processing thread. The implementation of this method must not block, access paged memory, or call any blocking system routines.
The Remote Desktop Services AudioEndpoint API is for use in Remote Desktop scenarios; it is not for client applications.
