SYNOPSIS
       #include "mpi.h"
       int MPI_File_get_size(MPI_File fh, MPI_Offset *size)

       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.
