index_typeType of index which determines the order:
  • H5_INDEX_NAME_F - Alphanumeric index on name
  • H5_INDEX_CRT_ORDER_F - Index on creation order
orderOrder within index:
  • H5_ITER_INC_F - Increasing order
  • H5_ITER_DEC_F - Decreasing order
  • H5_ITER_NATIVE_F - Fastest available order
idxIteration position at which to start, or
Position at which an interrupted iteration may be restarted
opCallback function passing data regarding the link to the calling application.
op_dataUser-defined pointer to data required by the application for its processing of the link.
return_valueReturn 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.
hdferrReturns 0 if successful and -1 if it fails.
