Note, you'll have to also put the file size "count" into OutputData,
and a position tracker, I'll call it "position", which should be
initialized to zero.

Then something like, (not tested):

------------------------------------
// Interleaved buffers
int output( void *outputBuffer, void *inputBuffer, unsigned int nBufferFrames,
            double streamTime, RtAudioStreamStatus status, void *data )
{
  int i;
  OutputData *oData = (OutputData*) data;
  MY_TYPE *out = (MY_TYPE *)outputBuffer;
  MY_TYPE *buf = &((MY_TYPE *)oData->buffer)[oData->position];
  for (i=0; i < nBufferFrames; i++) {
    if (oData->position < oData->count) {
        *out++ = *buf++;
        ++oData->position;
    } else
        *out++ = 0.0;
  }
  return (oData->position >= oData->count);
}
------------------------------------
