[Mpi-forum] MPI_Type_create_struct vs. other datatype creation routines

Is there a reason why MPI_Type_create_struct was given the special privilege of using MPI_Aint to store displacements, while the remaining datatype creation routines use int? This would essentially disallow creation of a datatype as an offset to MPI_BOTTOM. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
