This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the udp socket to use. Parameters:

handle Use this handle (fd or SOCKET). Note: close() will not be called on this handle.

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_UDP_SET_SERVICE, const char * service_name)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the udp service name to listen on. Parameters:

service_name The service name to use when setting up the listener. If the service name cannot be resolved, the port (if one is set) will be used instead.

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_UDP_GET_SERVICE, char ** service_name_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the service name to listen on. Parameters:

service_name_out A pointer to the service name will be stored here If none is set, NULL will be passed back. Otherwise, the name will be duplicated with strdup() and the user should call free() on it.

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_UDP_SET_PORT, int listener_port)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the port number to listen on. The default is 0 (system assigned)

Parameters:

listener_port The port number to use when setting up the listener. If the service name is also set, this will only be used if that can't be resolved.

globus_result_t globus_xio_attr_cntl (attr, driver, GLOBUS_XIO_UDP_GET_PORT, int * listener_port_out)

Used only where no specific service or port has been set. It overrides the range set in the GLOBUS_UDP_PORT_RANGE env variable. If 'restrict port' is true, the listening port will be constrained to the range specified.

Parameters:

See also:

GLOBUS_XIO_UDP_CONNECT

globus_result_t globus_xio_handle_cntl (handle, driver, GLOBUS_XIO_UDP_CONNECT, char * contact_string)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Set the default destination contact. Connecting a handle to a specific contact blocks packets from any other contact. It also sets the default destination of all outgoing packets so, using GLOBUS_XIO_UDP_SET_CONTACT is unnecessary.

Parameters:

contact_string A pointer to a contact string of the format <hostname/ip>:<port/service>

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Join a multicast group. Specifiy a multicast group to join. All packets received will be to the specified multicast address. Do not use GLOBUS_XIO_UDP_CONNECT, GLOBUS_XIO_UDP_SET_PORT, or pass a contact string on the open. Consider using GLOBUS_XIO_UDP_SET_REUSEADDR to allow other apps to join this group. Use GLOBUS_XIO_UDP_SET_INTERFACE to specify the interface to use. Will not affect handles set with GLOBUS_XIO_UDP_SET_HANDLE. GLOBUS_XIO_UDP_SET_RESTRICT_PORT is ignored.

Parameters:

contact_string A pointer to a contact string of the multicast group to join with the format: <hostname/ip>:<port/service>
