[Libevent-users] Re: question about evhttp_connection_free

[Han LIU <cn.liuhan@xxxxxxxxx>]

Sorry there was some mistake in the dummy code

The code should be

http_request_done_callback(struct evhttp_request *req, void *arg)
{
    if (req->evcon != NULL)
        evhttp_connection_free(req->evcon);
}

request_function()
{
   struct evhttp_connection *evcon = NULL;
   struct evhttp_request *req = NULL;
   evcon = evhttp_connection_base_new (u->eb, NULL, server_name, server_port);

   evhttp_connection_set_timeout (evcon, 30);
   evhttp_connection_set_retries (evcon, 5);

   req = evhttp_request_new (http_request_done_callback, NULL);

   if (evhttp_make_request (evcon, req, EVHTTP_REQ_GET, uri) == -1)
   {
       evhttp_connection_free (hco->evcon);
   }
}
