推荐答案

您必须保护对 std::queue 的访问.如果你使用 boost 保护它使用 boost::mutex.现在，如果您有多个阅读器和一个编写器线程，请查看 boost::shared_lock(用于阅读器)和 boost::unique_lock(用于编写器).

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).

但是，如果您遇到编写器线程不足的情况，请查看 boost::shared_mutex.

However if you will encounter writer thread starvation look at boost::shared_mutex.
