If the list were originally empty, you call pthread_cond_broadcast to post push data into the list.

如果列表原来是空的，就调用pthread_cond_broadcast以宣告列表中已经添加了数据。

If so, I simply push the record onto the existing list.

如果有，就将该记录写入现有的列表中。

After the loop is done, we push the length of the data at the end of the list.

循环完成后，我们将数据的长度压入到序列的尾部。
