DESCRIPTION
       MPIOpenport  establishes  a network address, encoded in the portname
       string, at which the server will be able  to  accept  connections  from
       clients. portname is supplied by the system.

       MPI  copies a system-supplied port name into portname. portname iden-
       tifies the newly opened port and can be used by a client to contact the
       server.  The  maximum size string that may be supplied by the system is
       MPIMAXPORTNAME.

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.
