InterlockedExchangePointer是否有替换c ++ 11(或boost)？

Question

寻找Win32 InterlockedExchangePointer的便携,简单和优雅的替代品.理想情况下只使用C++ 11,但也会使用boost.

Answer 1

该标准的原子类型有一个原子exchange功能.所以微软公司

PVOID volatile target;
old_value = InterlockedExchangePointer(&target, new_value);

会成为

std::atomic<T*> target;
old_value = target.exchange(new_value);
