                             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', 'MPI_File') are of type 'INTEGER' in Fortran.
