原创：vxworks的消息队列
一个任务运行时的数据和状态怎么告诉其他任务？信号量为任务间同步和互斥提供了提供了高效的方法，但它不能携带更多的任务信息。因而需要使用更高级的通讯方式，即消息队列和管道。这节主要讲消息队列。-Original: vxworks task message queue for run-time data and how to tell the status of other tasks? Semaphore for inter-task synchronization and mutual exclusion provides a way to provide a highly efficient, but it can not carry more information of the task. Therefore need to use more advanced means of communication, that is, message queue and the pipeline. This section stresses the main message queue.
