bool AudioIO::destroy (   )  [virtual]
 

deletes the data source for this IO class.

* not implemented, senseless for audio device!

Implements IO.

bool AudioIO::setToFrameNumber (  u32  frameNumber  )  [inline, virtual]
 

repositions the IO class to the given frame.

Will return false in the following cases:

  • an illegal frame number (too large) was specified
  • the stream is not seekable, because the underlying device is a network device and the requested frame is already out of range: FIXME: implement

Reimplemented from IO.
