std :: __ Atomic_thread_fence（大写A）正确吗？

Question

The Visual Studio 2012 c++ documentation states that _ReadBarrier and _WriteBarrier intrinsics are now deprecated:

The _ReadBarrier , _WriteBarrier , and _ReadWriteBarrier compiler intrinsics and the MemoryBarrier macro are all deprecated and should not be used. For inter-thread communication, use mechanisms such as atomic_thread_fence and std::atomic<T> that are defined in the C++ Standard Library Reference. For hardware access, use the /volatile:iso compiler option together with the volatile (C++) keyword.

Following the indications, I then jump to the atomic_thread_fence documentation and it states that the function is defined on header <atomic> . If I include such header on my solution, I can't find the function, but I do find std::_Atomic_thread_fence instead.

The naming suggests me this is a Microsoft-specific implementation. Is this a documentation problem or should I modify perhaps the default #include search paths?

This seems to simply be a problem with the Visual Studio intellisense. If you correct it to atomic_thread_fence it should work just as intended.
