.. _mpi_open_port:
MPI_Open_port
=============
.. include_body
:ref:`MPI_Open_port` |mdash| Establishes a network address for a server to accept
connections from clients.
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_Open_port(MPI_Info info, char *port_name)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_OPEN_PORT(INFO, PORT_NAME, IERROR)
CHARACTER*(*) PORT_NAME
INTEGER INFO, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_Open_port(info, port_name, ierror)
TYPE(MPI_Info), INTENT(IN) :: info
CHARACTER(LEN=MPI_MAX_PORT_NAME), INTENT(OUT) :: port_name
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
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
-----------
:ref:`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
------
