DirectMusic Stream Data Format

This example uses a KSDATAFORMAT structure to describe the data format of a DirectMusic stream.

  DataFormat.FormatSize  = sizeof(KSDATAFORMAT);
  DataFormat.Flags       = 0;
  DataFormat.SampleSize  = 0;
 DataFormat.Reserved    = 0;
  DataFormat.MajorFormat = STATICGUIDOF(KSDATAFORMAT_TYPE_MUSIC);
  DataFormat.SubFormat   = STATICGUIDOF(KSDATAFORMAT_SUBTYPE_DIRECTMUSIC);
  DataFormat.Specifier   = STATICGUIDOF(KSDATAFORMAT_SPECIFIER_NONE);
