             int count, MPI_Datatype datatype, MPI_Status *status)

INPUT PARAMETERS

       fh     - file handle (handle)
       offset - file offset (nonnegative integer)
       count  - number of elements in buffer (nonnegative integer)
       datatype

OUTPUT PARAMETERS

       buf    - initial address of buffer (choice)

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.
       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.
