NOTES FOR FORTRAN INTERFACE

The Fortran interface to this routine is different from its C counterpart and it has an additional argument, ierr, at the end of the argument list, i.e. the returned function value (the error code) in C interface is returned as the additional argument in Fortran interface. The Fortran interface is invoked with the CALL statement.

All MPI and MPE objects, MPI_Comm, MPE_XGraph and MPE_Color, are of type INTEGER in Fortran.
