The following code illustrates how to open a file.

   HMMCF hmmcf1;
   MMCFINFO mmcfinfo;
   MMIOINFO mmioinfo;
   ULONG ulFlags;
    ...

   memset( &mmcfinfo, '\0', sizeof(MMCFINFO));
   memset( &mmioinfo, '\0', sizeof(MMIOINFO));
   strcpy( pFileName, "myfile.bnd" );
   ulFlags = 0L;

   hmmcf1 = mmioCFOpen( pFileName, &mmcfinfo, &mmioinfo, ulFlags)
   if (!hmmcf1)
     /* error */
   else
    ...
