Yesterday I was going to ask a similar question, so I will use this
thread instead.

I've been reviewing the libcurl multi functions several times and I'm
unable to grasp how I could integrate CURL with my custom event loop.
The main obstacle is how to obtain the socket descriptor from a CURL
easy handle. Having a CURLMOPT_SOCKETFUNCTION does not seem to solve
the problem as it is only invoked with curl_multi_socket_action, where
you already need to know the descriptor.

I know I'm missing something, I just don't know what.
