<queue> queue threadsafe?

[Pixinger77]

Hi, I speak of the class std::queue / #include In my case the question is: 1. Is it safe to execute m_queue.push from thread A, while thread B executes m_queue.pop? 2. Is it safe to execute m_queue.push from thread A, while thread B executes m_queue.empty? 3. Is it safe to execute m_queue.push from thread A and also from thread B? I hope you understand what i mean, thanks in advance Snow.

None of the STL objects are thread safe. Wrap the calls in critical sections. Tim Smith I'm going to patent thought. I have yet to see any prior art.

Thanks for your answer Tim. I found an MSDN article "Thread Safety in the Standard C++ Library" which statet that some of the STL container classes are threadsafe (but only in certain cases). But I think it will be better to write a wrapper for the queue class as you wrote before. It seems to be the only way to be on the safe side. Thanks, Snow.
