_ReadWriteBarrier

Microsoft Specific

Limits the compiler optimizations that can reorder memory accesses across the point of the call.

Caution note Caution

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>, which are defined in the C++ Standard Template Library. For hardware access, use the /volatile:iso compiler option together with the volatile (C++) keyword.

void _ReadWriteBarrier(void);
