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 iden-
tifies 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++ func-
tions 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
Open MPI 1.2 March 2007 MPI_Open_port(3OpenMPI)
