 * Function:    H5Diterate
 *
 * Purpose: This routine iterates over all the elements selected in a memory
 *      buffer.  The callback function is called once for each element selected
 *      in the dataspace.  The selection in the dataspace is modified so
 *      that any elements already iterated over are removed from the selection
 *      if the iteration is interrupted (by the H5D_operator_t function
 *      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.
 *      hid_t type_id;      IN: Datatype ID for the elements stored in BUF.
 *      hid_t space_id;     IN: Dataspace ID for BUF, also contains the
 *                              selection to iterate over.
 *      H5D_operator_t op; IN: Function pointer to the routine to be
 *                              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.
