Render method renders wave data into a destination sink.
- pbBuffer [in]
Pointer to the buffer that the synth sink wants data written to
- dwLength [in]
Specifies the length (in bytes) of the data to be rendered.
- llPosition [in]
Specifies the position (in bytes) in the PCM buffer at which to begin rendering. Rendering continues from this position for the number of bytes specified in dwLength.
The port driver's synth-sink object calls this method when the miniport driver needs to render more wave data into the destination buffer.
