INPUT PARAMETERS

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

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.
