mqttkit 如何取消自动重连

Question

如题，项目需要，我们用mqtt协议做远程控制。通信双方为mqtt服务器和两个ios APP，A和B .
现在我用同一个账号（如账号：[e-mail] 密码：123456）先在A客户端登录，然后再用这个账号登录B客户端。这时B会把A挤掉，重新连上，（重连成功后发订阅，也会一直发订阅）。待B登陆成功，A掉线后，A又自动重连。就这样一直挤掉对方。请问该如何取消mqtt Client的自动重连？

int mosquitto_loop_forever(struct mosquitto *mosq, int timeout, int max_packets)
{
int run = 1;
int rc;
unsigned int reconnects = 0;
unsigned long reconnect_delay;

if(!mosq) return MOSQ_ERR_INVAL;

if(mosq->state == mosq_cs_connect_async){
    mosquitto_reconnect(mosq);
}

while(run){
    do{
        rc = mosquitto_loop(mosq, timeout, max_packets);
        if (reconnects !=0 && rc == MOSQ_ERR_SUCCESS){
            reconnects = 0;
        }
    }while(rc == MOSQ_ERR_SUCCESS);
    if(errno == EPROTO){
        return rc;
    }
    pthread_mutex_lock(&mosq->state_mutex);
    if(mosq->state == mosq_cs_disconnecting){
        run = 0;
        pthread_mutex_unlock(&mosq->state_mutex);
    }else{
        pthread_mutex_unlock(&mosq->state_mutex);

        if(mosq->reconnect_delay > 0 && mosq->reconnect_exponential_backoff){
            reconnect_delay = mosq->reconnect_delay*reconnects*reconnects;
        }else{
            reconnect_delay = mosq->reconnect_delay;
        }

        if(reconnect_delay > mosq->reconnect_delay_max){
            reconnect_delay = mosq->reconnect_delay_max;
        }else{
            reconnects++;
        }

#ifdef WIN32
Sleep(reconnect_delay*1000);
#else
sleep(reconnect_delay);
#endif

        pthread_mutex_lock(&mosq->state_mutex);
        if(mosq->state == mosq_cs_disconnecting
           || mosq->state == mosq_cs_connected){
            run = 0;
            pthread_mutex_unlock(&mosq->state_mutex);
        }else{
            pthread_mutex_unlock(&mosq->state_mutex);
            mosquitto_reconnect(mosq);
        }
    }
}
return rc;
