MPI_Open_port(3)                   Open MPI                   MPI_Open_port(3)



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.
