 * Purpose: Implicit (Non Index) chunked I/O functions.  
 *      This is used when the dataset is:
 *          extendible but with fixed max. dims
 *          with early allocation
 *          without filter
 *      The chunk coordinate is mapped into the actual disk addresses
 *      for the chunk without indexing.
