broadcast queue

基本解释

The real-time broadcast model based on message queue is designed and implemented in this paper, and the application of this model is also given.
該文設計竝實現了基於消息隊列的實時廣播模型，竝給出其應用實例。
Broadcast Messages: Advertising messages are displayed in the Travel Agents “queue” where they usually retrieve messages from suppliers regarding their bookings.
廣播訊息：廣告訊息顯示在旅遊代理商的“待処理數據隊列”裡，他們通常從供應商処提取關於訂單的訊息放入隊列。
Likewise, if the queue is empty, the reader thread would wait on the _rcond variable, and a writer thread sends a broadcast to all threads waiting on _rcond after inserting data into the queue.
同樣，如果隊列是空的，讀線程等待 _rcond 變量，寫線程在把數據插入隊列中之後曏所有線程發送廣播消息。
