paho_mqtt_thread 里面的connect_callback连接成功回调怎么是在连接开始的时候，不应该是连接服务器成功之后吗，不知道我理解对不对

_mqtt_start:
//源码位置，这个是连接开始前调用
if (c->connect_callback)
{
c->connect_callback(c);
}

rc = net_connect(c);
if (rc != 0)
{
    LOG_E("Net connect error(%d).", rc);
    goto _mqtt_restart;
}

rc = MQTTConnect(c);
if (rc != 0)
{
    LOG_E("MQTT connect error(%d): %s.", rc, MQTTSerialize_connack_string(rc));
    goto _mqtt_restart;
}
//此处连接成功，应该调用？
//if (c->connect_callback)
//{

// c->connect_callback(c);
// }
LOG_I("MQTT server connect success.");
