Re: [Libevent-users] Connect to server failed, libevent return BEV_EVENT_ERROR event and BEV_EVENT_CONNECTED event?

[Dawen Rie <dawenhing@xxxxxxx>]

As nobody answer my question for a long time, 

I try to solve the problem by adding a 

event_base_loopbreak(base);

When BEV_EVENT_ERROR occurred. 

Is it really the normal solution for such kind of problem?

I just write a simple client, and try to connect to a server which NOT

running.

libevent will trigger eventcb too times, the first time is BEV_EVENT_ERROR

and the second time is BEV_EVENT_CONNECTED. Is there some wrong with me?

The code like following:

static void eventcb(struct bufferevent *bev, short events, void *ptr)

{

    if (events & BEV_EVENT_CONNECTED) {

printf("Connected\n");

//login(bev);

    } else if (events & BEV_EVENT_ERROR) {

     printf("NOT Connected\n");

    }

}

static void readcb(struct bufferevent *bev, void *ctx)

{

}

int main(int argc, char **argv)

{

    if (argc != 3) {

printf("Usage: client <host> <port>\n");

return 1;

    }

    const char *host = argv[1];

    int port = atoi(argv[2]);

    struct event_base *base = event_base_new();

    if (!base) {

printf("Couldn't open event base\n");

return 1;

    }

    

    struct bufferevent *bev = bufferevent_socket_new(base, -1,

BEV_OPT_CLOSE_ON_FREE);

    bufferevent_setcb(bev, readcb, NULL, eventcb, NULL);

    bufferevent_enable(bev, EV_READ|EV_WRITE);

    printf("Connecting to %s:%d\n", host, port);

    if(bufferevent_socket_connect_hostname(bev, NULL, AF_INET, host, port)

!= 0)

    {

        printf("Connect host failed\n");

        return 1;

    }

    

    event_base_dispatch(base);

    bufferevent_free(bev);

    event_base_free(base);

    return 0;

}
