_ReadBarrier
Microsoft Specific
Limits the compiler optimizations that can reorder memory access operations across the point of the call.
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> that are defined in the C++ Standard Library. For hardware access, use the /volatile:iso compiler option together with the volatile keyword.
Syntax
void _ReadBarrier(void);

Remarks
The _ReadBarrier
intrinsic limits the compiler optimizations that can remove or reorder memory access operations across the point of the call.
