The following code illustrates how to open a file for I/O.

   HMMIO hmmio1;
   MMIOINFO mmioinfo;
   ULONG ulFlags = 0L;
    ...

   memset( &mmioinfo, '\0', sizeof(MMIOINFO) );
   mmioinfo.fccIOProc = FOURCC_WAVE;
   ulFlags |= MMIO_READ | MMIO_DENYNONE;

   hmmio1 = mmioOpen("sounds.bnd+train.wav", &mmioinfo, ulFlags);
   if (!hmmio1)

     /* error */
   else
    ...
