: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.
