loc_id	File or group identifier specifying location of subject group.
group_name	Name of subject group.
index_type	Type of index which determines the order: H5_INDEX_NAME_F - Alphanumeric index on name H5_INDEX_CRT_ORDER_F - Index on creation order
order	Order within index: H5_ITER_INC_F - Increasing order H5_ITER_DEC_F - Decreasing order H5_ITER_NATIVE_F - Fastest available order
idx	Iteration position at which to start, or Position at which an interrupted iteration may be restarted
op	Callback function passing data regarding the link to the calling application.
op_data	User-defined pointer to data required by the application for its processing of the link.
return_value	Return context: Success: The return value of the first operator that returns non-zero, or zero if all members were processed with no operator returning non-zero. Failure: Negative if something goes wrong within the library, or the negative value returned by one of the operators.
hdferr	Returns 0 if successful and -1 if it fails.
lapl_id	Link access property list
