 <p class="level0">Pass a pointer to your callback function, which should match the prototype shown above. 
 <p class="level0">This callback function gets called by libcurl instead of the <span Class="emphasis">socket(2)</span> call. The callback's <span Class="emphasis">purpose</span> argument identifies the exact purpose for this particular socket: <span Class="emphasis">CURLSOCKTYPE_IPCXN</span> is for IP based connections and <span Class="emphasis">CURLSOCKTYPE_ACCEPT</span> is for sockets created after accept() - such as when doing active FTP. Future versions of libcurl may support more purposes. 
 <p class="level0">The <span Class="emphasis">clientp</span> pointer contains whatever user-defined value set using the <a Class="emphasis" href="./CURLOPT_OPENSOCKETDATA.html">CURLOPT_OPENSOCKETDATA</a> function. 
 <p class="level0">The callback gets the resolved peer address as the <span Class="emphasis">address</span> argument and is allowed to modify the address or refuse to connect completely. The callback function should return the newly created socket or <span Class="emphasis">CURL_SOCKET_BAD</span> in case no connection could be established or another error was detected. Any additional <span Class="emphasis">setsockopt(2)</span> calls can of course be done on the socket at the user's discretion.  A <span Class="emphasis">CURL_SOCKET_BAD</span> return value from the callback function will signal an unrecoverable error to libcurl and it will return <span Class="emphasis">CURLE_COULDNT_CONNECT</span> from the function that triggered this callback. This return code can be used for IP address blacklisting. 
 <p class="level0">If you want to pass in a socket with an already established connection, pass the socket back with this callback and then use <a Class="emphasis" href="./CURLOPT_SOCKOPTFUNCTION.html">CURLOPT_SOCKOPTFUNCTION</a> to signal that it already is connected. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
