       rtnl_open
              Open a rtnetlink socket and save the state into the rth handle.
              This handle is passed to all subsequent calls.  subscriptions is
              a bitmap of the rtnetlink multicast groups the socket will be a
              member of.


       rtnl_wilddump_request
              Request a full dump of the type database for family addresses.
              type is a rtnetlink message type.


       rtnl_dump_request
              Request a full dump of the type data buffer into buf with
              maximum length of len. type is a rtnetlink message type.


       rtnl_dump_filter
              Receive netlink data after a request and filter it.  The filter
              callback checks if the received message is wanted. It gets the
              source address of the message, the message itself and arg1 as
              arguments. 0 as return means that the filter passed, a negative
              value is returned by rtnl_dump_filter in case of error. NULL for
              filter means to not use a filter.  junk is used to filter
              messages not destined to the local socket.  Only one message
              bundle is received. If there is a message pending, this function
              does not block.


       rtnl_listen
              Receive netlink data after a request and pass it to handler.
              handler is a callback that gets the message source address,
              anscillary data, the message itself, and the jarg cookie as
              arguments. It will get called for all received messages.  Only
              one message bundle is received. If there is a message pending
              this function does not block.

              rtnetlink.

       The following functions are useful to construct custom rtnetlink
       messages. For simple database dumping with filtering it is better to
       use the higher level functions above. See rtnetlink(3)  and netlink(3)
       on how to generate a rtnetlink message. The following utility functions
       require a continuous buffer that already contains a netlink message
       header and a rtnetlink request.


       rtnl_send
              Send the rtnetlink message in buf of length len to handle rth.
