You need to use the multi_socket API. It is designed to export the sockets
libcurl use and to allow you to do all the event and socket handling.
See http://curl.haxx.se/libcurl/c/curl_multi_socket_action.html

No, you can also call it as a timeout (see the man page for details on how),
which you can/should do as a first call to get it going the first time.
