 246 structure that will then be used by other libmemcached(3) functions to
 247 communicate with the server. You should either pass a statically declared

 254 <a class="reference internal" href="#_CPPv412memcached_st" title="memcached_st"><code class="xref cpp cpp-type docutils literal notranslate"><span class="pre">memcached_st</span></code></a>. If you pass a null as the argument for the source
