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.
