how can I make a queue thread safe? I need to push / pop / front / back and clear. is there something similar in boost?
我有一个生产者和一个或多个消费者
I have one producer and one or more consumer.
答
您必须保护访问的std ::队列
。如果您在使用升压保护它使用的boost ::互斥
。现在,如果你有多个读者和一位作家线程看看的boost :: shared_lock
(读者)和的boost :: unique_lock
(对于作家)。
You must protect access to std::queue
. If you are using boost protect it using boost::mutex
. Now if you have multiple readers and one writer thread look at boost::shared_lock
(for readers) and boost::unique_lock
(for writer).
然而,如果你将遇到的作家线程匮乏看看的boost :: shared_mutex
。
However if you will encounter writer thread starvation look at boost::shared_mutex
.
