MPI_Datatype datatype)
.fi
.SH INPUT PARAMETERS
.PD 0
.TP
.B fh
- file handle (handle)
.PD 1
.PD 0
.TP
.B buf
- initial address of buffer (choice)
.PD 1
.PD 0

.SH NOTES FOR FORTRAN
All MPI routines in Fortran (except for
.I MPI_WTIME
and
.I MPI_WTICK
)
have an additional argument
.I ierr
at the end of the argument list.
.I 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
.I call
statement.
All MPI objects (e.g.,
.I MPI_Datatype
,
.I MPI_Comm
) are of type
.I INTEGER
in Fortran.
