GetPosition method retrieves the current play or record position as a byte offset from the beginning of the buffer.
- AudioPosition [out]
Pointer to a KSAUDIO_POSITION structure. For a wave rendering stream, the method writes the write position and the play position into this structure. For a wave-capture stream, the method writes the read position and the record position into the structure. Positions are specified as byte offsets from the beginning of the cyclic buffer.
GetPosition returns STATUS_SUCCESS if the call was successful. Otherwise, the function returns an appropriate error status code.
The WaveRT port driver calls this method in response to a KSPROPERTY_AUDIO_POSITION property request from a client.
