 * Function:	H5Dcreate2
 *
 * Purpose:	Creates a new dataset named NAME at LOC_ID, opens the
 *		dataset for access, and associates with that dataset constant
 *		and initial persistent properties including the type of each
 *		datapoint as stored in the file (TYPE_ID), the size of the
 *		dataset (SPACE_ID), and other initial miscellaneous
 *		properties (DCPL_ID).
 *
 *		All arguments are copied into the dataset, so the caller is
 *		allowed to derive new types, dataspaces, and creation
 *		parameters from the old ones and reuse them in calls to
 *		create other datasets.
 *
 * Return:	Success:	The object ID of the new dataset.  At this
 *				point, the dataset is ready to receive its
 *				raw data.  Attempting to read raw data from
 *				the dataset will probably return the fill
 *				value.	The dataset should be closed when the
 *				caller is no longer interested in it.

 * Function:	H5Diterate
 *
 * Purpose:	This routine iterates over all the elements selected in a memory

 *      that any elements already iterated over are removed from the selection

 *      returning non-zero) in the "middle" of the iteration and may be
 *      re-started by the user where it left off.
 *
 *      NOTE: Until "subtracting" elements from a selection is implemented,
 *          the selection is not modified.
 *
 * Parameters:
 *      void *buf;          IN/OUT: Pointer to the buffer in memory containing
 *                              the elements to iterate over.

 *                              called for each element in BUF iterated over.
 *      void *operator_data;    IN/OUT: Pointer to any user-defined data
 *                              associated with the operation.
 *
 * Operation information:
 *      H5D_operator_t is defined as:
 *          typedef herr_t (*H5D_operator_t)(void *elem, hid_t type_id,
 *              unsigned ndim, const hsize_t *point, void *operator_data);
 *
 *      H5D_operator_t parameters:
 *          void *elem;         IN/OUT: Pointer to the element in memory containing
 *                                  the current point.
 *          hid_t type_id;      IN: Datatype ID for the elements stored in ELEM.
 *          unsigned ndim;       IN: Number of dimensions for POINT array
 *          const hsize_t *point; IN: Array containing the location of the element
 *                                  within the original dataspace.
 *          void *operator_data;    IN/OUT: Pointer to any user-defined data
 *                                  associated with the operation.
 *
 *      The return values from an operator are:
 *          Zero causes the iterator to continue, returning zero when all
 *              elements have been processed.
 *          Positive causes the iterator to immediately return that positive
 *              value, indicating short-circuit success.  The iterator can be
 *              restarted at the next element.
 *          Negative causes the iterator to immediately return that value,
 *              indicating failure. The iterator can be restarted at the next
 *              element.
 *
 * Return:	Returns the return value of the last operator if it was non-zero,
 *          or zero if all elements were processed. Otherwise returns a
 *          negative value.
