           GLOBUS_XIO_GET_LOCAL_CONTACT

   globus_result_t globus_xio_data_descriptor_cntl (dd, driver,
       GLOBUS_XIO_UDP_GET_NUMERIC_CONTACT, char ** contact_string_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 contact string associated with a
       handle or data descriptor.

       Use with globus_xio_handle_cntl() to get a contact string for the udp listener. Use with
       globus_xio_data_descriptor_cntl() to get the sender's contact string from a data
       descriptor passed to globus_xio_register_read().

       Parameters
           contact_string_out A pointer to a contact string will be stored here. The user should
           free() it when done with it. It will be in the format: <ip>:<port>

   globus_result_t globus_xio_data_descriptor_cntl (dd, driver, GLOBUS_XIO_UDP_SET_CONTACT, 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 destination contact.

       Use on a data descriptor passed to globus_xio_register_write() to specify the recipient of
       the data. This is necessary with unconnected handles or to send to recipients other than
       the connected one.

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

   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>

   globus_result_t globus_xio_handle_cntl (handle, driver, GLOBUS_XIO_UDP_GET_CONTACT, char **
       contact_string_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 contact string associated with a
       handle or data descriptor.

       Use with globus_xio_handle_cntl() to get a contact string for the udp listener. Use with
       globus_xio_data_descriptor_cntl() to get the sender's contact string from a data
       descriptor passed to globus_xio_register_read().

       Parameters
           contact_string_out A pointer to a contact string will be stored here. The user should
           free() it when done with it. It will be in the format: <hostname>:<port>

       This is an overloaded member function, provided for convenience. It differs from the above
       function only in what argument(s) it accepts. Get the socket handle on an attr or handle.

       Parameters
           handle_out The udp socket will be stored here. If none is set,
           GLOBUS_XIO_UDP_INVALID_HANDLE will be set.
