DESCRIPTION
       This routine removes the pair (servicename, portname) so that  appli-
       cations may no longer retrieve portname by calling MPILookupname. It
       is an error to unpublish a servicename  that  was  not  published  via
       MPIPublishname.  Both  the  servicename  and  portname arguments to
       MPIUnpublishname must be identical to the arguments to  the  previous
       call to MPIPublishname.

       The  info  parameter  should be MPIINFONULL, as this routine does not
       parse any MPI Info arguments.


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.

       See the MPI man page for a full list of MPI error codes.
