       group1    First group (handle).

       n         Number of ranks in ranks1 and ranks2 arrays (integer).

       ranks1    Array of zero or more valid ranks in group1.

       group2    Second group (handle).


OOUUTTPPUUTT PPAARRAAMMEETTEERRSS
       ranks2    Array of corresponding ranks in group2, MPIUNDEFINED when no
                 correspondence exists.

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       This  function  is  important for determining the relative numbering of
       the same processes in two different groups. For instance, if one  knows
       the  ranks  of  certain  processes  in the group of MPICOMMWORLD, one
       might want to know their ranks in a subset of that group.


EERRRROORRSS
       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORSTHROWEXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI  error  handler  is
       called.  By  default, this error handler aborts the MPI job, except for
       I/O  function  errors.  The  error  handler   may   be   changed   with
       MPICommseterrhandler; the predefined error handler MPIERRORSRETURN
       may be used to cause error values to be returned. Note  that  MPI  does
       not guarantee that an MPI program can continue past an error.
