I am some confused in using IDmaChannel::copyto and copyfrom. I am writing a
virtual wdm audio catpute driver, since it is a virtual driver, the audio
data is not from a real device, it is from an application. Which function
copyto or coypfrom I should use to send the data to the driver? Thank you
very much.
