In Fortran, the functions MPI_TYPE_CREATE_HVECTOR, MPI_TYPE_CREATE_HINDEXED, MPI_TYPE_CREATE_HINDEXED_BLOCK, MPI_TYPE_CREATE_STRUCT, and MPI_GET_ADDRESS accept arguments of type INTEGER(KIND=MPI_ADDRESS_KIND), wherever arguments of type MPI_Aint are used in C. On Fortran 77 systems that do not support the Fortran 90 KIND notation, and where addresses are 64 bits whereas default INTEGERs are 32 bits, these arguments will be of type INTEGER*8.
