MPI_FILE_GET_SIZE(fh, size)
IN fhfile handle (handle)
OUT sizesize of the file in bytes (integer)

int MPI_File_get_size(MPI_File fh, MPI_Offset *size)
MPI_FILE_GET_SIZE(FH, SIZE, IERROR)
INTEGER FH, IERROR
INTEGER(KIND=MPI_OFFSET_KIND) SIZE
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 , page File Consistency ).
