MPI_Open_port(3OpenMPI)                                                              MPI_Open_port(3OpenMPI)



NAME
       MPI_Open_port - Establishes a network address for a server to accept connections from clients.


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


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


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


INPUT PARAMETER
       info      Options on how to establish an address (handle). No options currently supported.


OUTPUT PARAMETERS
       port_name Newly established port (string).

       IERROR    Fortran only: Error status (integer).


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

       MPI copies a system-supplied port name into port_name. port_name identifies 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 MPI_MAX_PORT_NAME.


SUPPORTED INFO KEYS
       None.


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.
