MPI_Unpublish_name(3OpenMPI)                                                    MPI_Unpublish_name(3OpenMPI)



NAME
       MPI_Unpublish_name - Unpublishes a service name


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Unpublish_name(char *service_name, MPI_Info info,
            char *port_name)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_UNPUBLISH_NAME(SERVICE_NAME, INFO, PORT_NAME, IERROR)
            CHARACTER*(*)  SERVICE_NAME, PORT_NAME
            INTEGER        INFO, IERROR


C++ Syntax
       #include <mpi.h>
       void MPI::Unpublish_name(const char* service_name, const MPI::Info& info,
            char* port_name)


INPUT PARAMETERS
       service_name  A service name (string).

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

       port_name     A port name (string).


OUTPUT PARAMETER
       IERROR        Fortran only: Error status (integer).


DESCRIPTION
       This  routine  removes the pair (service_name, port_name) so that applications may no longer retrieve
       port_name by calling MPI_Lookup_name. It is an error to unpublish a service_name that  was  not  pub-lished published
       lished via MPI_Publish_name. Both the service_name and port_name arguments to MPI_Unpublish_name must
       be identical to the arguments to the previous call to MPI_Publish_name.

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


ERRORS
       Almost all MPI routines return an error value; C routines as the value of the  function  and  Fortran
       routines  in  the  last argument. C++ functions do not return errors. If the default error handler is
       set to MPI::ERRORS_THROW_EXCEPTIONS, 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
       MPI_Comm_set_errhandler;  the  predefined  error handler MPI_ERRORS_RETURN 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.
