is std::queue thread safe with producer and multiple consumers

Question

how can I make a queue thread safe? I need to push / pop / front / back and clear. is there something similar in boost?

I have one producer and one or more consumer.

Answer 1

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).

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