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.
