itaps-parallel tiny question

[Mark Miller]

I have a question on the 'Arr' form of these functions (below)...

  void prefix_getPartsArrOnRank(iMesh_Instance instance,
                       const prefix_PartitionHandle partition_handle,
             /*in*/    const int *rank,
             /*in*/    const int rank_size,
             /*inout*/ prefix_PartHandle **part_handles,
             /*inout*/ int *part_handles_allocated,
             /*out*/   int *part_handles_size,
                       int *err);

We pass in an array of ranks and get back an array of part_handles.
How do we know which entries in part_handles go with which rank
in the input list of ranks? I guess we could iterate over the returned
part_handles using prefix_getPartRank.

    void prefix_getPartNborsArr(iMesh_Instance instance,
                       const prefix_PartitionHandle partition_handle,
             /*in*/    const prefix_PartHandle *part_handles,
             /*in*/    const int part_handles_size,
             /*in*/    int entity_type,
             /*inout*/ prefix_PartHandle **nbor_part_handles,
             /*inout*/ int *nbor_part_handles_allocated,
             /*out*/   int *nbor_part_handles_size,
                       int *err);

In the above, we pass an array of part_handles and get back an
array of neighboring part handles. How do we know which part
handles in nbor_part_handles go with whith entries in part_handles?
