[ IN fh] file handle (handle)
[ OUT size] size of the file in bytes (integer)
int MPI_File_get_size(MPI_File fh, MPI_Offset *size)

INTEGER FH, IERROR
MPI::Offset MPI::File::Get_size() const
MPI_FILE_GET_SIZE returns, in size, the current size in bytes of the file associated with the file handle fh. As far as consistency semantics are concerned, MPI_FILE_GET_SIZE is a data access operation (see Section File Consistency ).
