Callback for socket options in curl + c-ares

From: Francisco Sedano Crippa (fsedanoc) <fsedanoc_at_cisco.com>

Hello folks,

In our environment, we need to setup some socket options before sockets can be used, and we need to use curl + c-ares.

Ideally I’d like to setup a callback with ares_set_socket_configure_callback(), but in order to do so, I need access to internal libcurl c-ares channel, which is embedded in the Curl_easy structure.

Is there any way to access such c-ares channel so I can properly intercept c-ares socket usage, like we can do with CURLOPT_OPENSOCKETFUNCTION in libcurl?

Thanks!
