EXAMPLE

     static gboolean timeout_cb(gpointer user_data)
     {
       int running;
       if(user_data) {
         g_free(user_data);
         curl_multi_setopt(curl_handle, CURLMOPT_TIMERDATA, NULL);
       }
       curl_multi_socket_action(multi, CURL_SOCKET_TIMEOUT, 0, &running);
       return G_SOURCE_REMOVE;
     }

     static int timerfunc(CURLM *multi, long timeout_ms, void *userp)
     {
       guint *id = userp;

       if(id)
         g_source_remove(*id);

       /* -1 means we should just delete our timer. */
       if(timeout_ms == -1) {
         g_free(id);
         id = NULL;
       }
       else {
         if(!id)
           id = g_new(guint, 1);
         *id = g_timeout_add(timeout_ms, timeout_cb, id);
       }
       curl_multi_setopt(multi, CURLMOPT_TIMERDATA, id);
