mosquitto_loop_forever()是一个阻塞调用,适用于你只想在回调中处理传入消息的情况。换句话说,调用这个函数,该函数内部调用了一个while(1)循环和mosquitto_loop(),接下来你什么也不能干。 mosquitto_loop_start() & mosquitto_loop_stop()# mosquitto_loop_start(),调用一次以启动一个新线程来处理网络流量。mosqu...

loop函数主要的用途在于读取、写入接收缓存区的或者发送缓冲区中的数据,并调用对应的回调函数。 Understanding The Loop -Using The Python MQTT Client When writing code using the Paho Python client you would have had to use the loop() function . ...

no-loop:可以理解为它只针对当前规则生效,如果当前规则的RHS部分发生了变更,导致当前规则触发,那么它不会在执行。 lock-on-active:这个一般和agenda-group或ruleflow-group结合使用,它可以保证当前规则只...
But on windows, pthread_win32 implementation, socket family system call is not thread cancellation point, that means if i enable the thread support in mosquitto, there wouldn't be any thread cacellation point in mosquitto_loop_forever. So if calling mosquitto_loop_stop(mosq, true), then the...
