MPI_File_get_type_extent(3)

NAME
MPI_File_get_type_extent - Returns the extent of datatype in the file

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

INPUT PARAMETERS
fh  - file handle (handle)
datatype
    - datatype (handle)

OUTPUT PARAMETERS
extent
    - extent of the datatype (nonnegative integer)

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. ierr is an integer and has the same meaning as the return value of 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 ) are of type INTEGER in Fortran.
