int MPI_Type_get_contents(datatype, max_integers, max_addresses, max_datatypes, array_of_integers, array_of_addresses, array_of_datatypes)
MPI_Datatype  datatype;
int           max_integers;
int           max_addresses;
int           max_datatypes;
int           *array_of_integers;
MPI_Aint      *array_of_addresses;
MPI_Datatype  *array_of_datatypes;

Input Parameters

Output Parameters

	datatype	datatype to access (handle)
	max_integers	number of elements in array_of_integers (non-negative integer)
	max_addresses	number of elements in array_of_addresses (non-negative integer)
	max_datatypes	number of elements in array_of_datatypes (non-negative integer)
	array_of_integers	contains integer arguments used in constructing datatype (array of integers)
	array_of_addresses	contains address arguments used in constructing datatype (array of integers)
	array_of_datatypes	contains datatype arguments used in constructing datatype (array of handles)

Notes for Fortran

All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement.

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGER in Fortran.
