16   Initializes the dumping handle, grabs the statistic lock and appends
17   an empty TLV header to the socket buffer for use a container for all
18   other statistic TLVS.

21   The dumping handle is marked to be in backward compatibility mode telling
22   all <code class="function">gnet_stats_copy_XXX</code> functions to fill a local copy of struct tc_stats.

24
25   Returns 0 on success or -1 if the room in the socket buffer was not sufficient.
