/*
|

|
|
* 这个例程适用于`Linux`这类支持pthread的POSIX设备, 它演示了用SDK配置MQTT参数并建立连接, 之后创建2个线程
|
||
|
|
*
|
||
|
|
* + 一个线程用于保活长连接
|
||
|
|
* + 一个线程用于接收消息, 并在有消息到达时进入默认的数据回调, 在连接状态变化时进入事件回调
|
||
|
|
*
|
||
|
|
* 接着在MQTT连接上发送NTP查询请求, 如果云平台的回应报文到达, 从接收线程会调用NTP消息处理的回调函数, 把对时后的本地时间打印出来
|
||
|
|
*
|
||
|
|
* 需要用户关注或修改的部分, 已经用 TODO 在注释中标明
|
