Re: [Libevent-users] Handling the connection close

This is an example in http.c
I wonder how can I get EVHTTP_CON_READING_ERROR?? Since when the connection is closed, I can only get an error code, and this code seems only telling your send or recv has finished or not. 

evhttp_connection_read_on_write_error(struct evhttp_connection *evcon,
    struct evhttp_request *req)
{
    struct evbuffer *buf;

    /** Second time, we can't read anything */
    if (evcon->flags & EVHTTP_CON_READING_ERROR) {
        evcon->flags &= ~EVHTTP_CON_READING_ERROR;
        evhttp_connection_fail_(evcon, EVREQ_HTTP_EOF);
        return;
    }

    req->kind = EVHTTP_RESPONSE;

    buf = bufferevent_get_output(evcon->bufev);
    evbuffer_unfreeze(buf, 1);
    evbuffer_drain(buf, evbuffer_get_length(buf));
    evbuffer_freeze(buf, 1);

    evhttp_start_read_(evcon);
    evcon->flags |= EVHTTP_CON_READING_ERROR;
}

Hi all,

I want to ask what should I do when the connection is closed while I am
sending or recving data. For example the connection is closed by the server
explicitly or because the server is down, when the client is still sending
data or recving data. For libevent, if the connection is closed, event
callback is invoked. But in this callback what should we do? Is there any
common practice?

That depends on your needs, you can take a look at http server for
example:
$ grep EOF libevent/http.c
