MPI_File_write_at - Write using explict offset

fh     - file handle (handle)
       offset - file offset (nonnegative integer)
       buf    - initial address of buffer (choice)
       count  - number of elements in buffer (nonnegative integer)
       datatype
              - datatype of each buffer element (handle)

       MPI_File_write_at -  Write using explict offset

       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.

status - status object (Status)
