# SYSTEM QUEUE

##  简介

该示例会在开始的时候创建两个线程， `__queue_post_task` 和 `__queue_fetch_task` ，`__queue_post_task` 线程会每隔 5s 就回向队列中释放一条数据，`__queue_fetch_task` 线程一直阻塞着等待着队列中有数据到来，然后打印从队列中取出来的数据。

## 运行结果
```C
[01-01 00:00:13 ty D][tal_thread.c:203] Thread:queue_post Exec Start. Set to Running Stat
[01-01 00:00:13 ty N][example_queue.c:51] post queue

[01-01 00:00:13 ty D][tal_thread.c:203] Thread:queue_fetch Exec Start. Set to Running Stat
