       servicename  A service name (string).

       info          Options  to  the  name  service  functions  (handle).  No
                     options currently supported.

       portname     a port name (string).

       IERROR        Fortran only: Error status (integer).


DESCRIPTION
       This function retrieves a portname published under servicename  by  a
       previous  invocation of MPIPublishname. The application must supply a
       portname buffer large enough to hold the largest  possible  port  name
       (i.e., MPIMAXPORTNAME bytes).

       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.
