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 published 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++ func-
       tions 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.

NAME

       MPI_Comm_accept	- Establishes communication with a client.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Comm_accept(char *port_name, MPI_Info info, int root, MPI_Comm comm, MPI_Comm *newcomm)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_ACCEPT(PORT_NAME, INFO, ROOT, COMM, NEWCOMM, IERROR)
	    CHARACTER*(*)  PORT_NAME
	    INTEGER	   INFO, ROOT, COMM, NEWCOMM, IERROR

C++ Syntax
       #include <mpi.h>
       MPI::Intercomm MPI::Intracomm::Accept(const char* port_name,
	    const MPI::Info& info, int root) const

INPUT PARAMETERS

       port_name Port name (string, used only on root).

       info	 Options given by root for the accept (handle, used only on root). No options currently supported.

       root	 Rank in comm of root node (integer).

       comm	 Intracommunicator over which call is collective (handle).

OUTPUT PARAMETERS

       newcomm	 Intercommunicator with client as remote group (handle)

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Comm_accept	establishes  communication  with a client. It is collective over the calling communicator. It returns an intercommunicator
       that allows communication with the client, after the client has connected with the  MPI_Comm_accept  function  using  the  MPI_Comm_connect
       function.

       The port_name must have been established through a call to MPI_Open_port on the root.

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++ func-
       tions 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.
