The following code illustrates how to determine the storage system of a data object.

   MMIOINFO mmioinfo;
   FOURCC fccType;
   PSZ pszParsedFileName;
   ULONG rc;
    ...

   rc = mmioDetermineSSIOProc( "DAN.BND+SUE.WAV",
                               &mmioinfo,
                               &fccType,
                               pszParsedFileName);
   if (rc)
     /* error */
   else
    ...
