.TH MPI_File_get_size 3 "2/5/1998" " " "MPI-2".SH NAMEMPI_File_get_size \-  Returns the file size .SH SYNOPSIS.nf#include "mpi.h"int MPI_File_get_size(MPI_File fh, MPI_Offset *size).fi.SH INPUT PARAMETERS.PD 0.TP.B fh - file handle (handle).PD 1.SH OUTPUT PARAMETERS.PD 0.TP.B size - size of the file in bytes (nonnegative integer).PD 1.SH NOTES FOR FORTRANAll 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 ofthe routine in C.  In Fortran, MPI routines are subroutines and areinvoked with the 'call' statement.All MPI objects (e.g., 'MPI_Datatype', 'MPI_Comm', 'MPI_File') are oftype 'INTEGER' in Fortran.
