       int MPI_File_get_type_extent(MPI_File fh, MPI_Datatype datatype,
				    MPI_Aint *extent)

INPUT PARAMETERS

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.
       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', 'MPI_File') are of type 'INTEGER' in Fortran.
