std::atomic_fetch_xor
STD：：原子[医]去取[医]XOR，STD：：原子[医]去取[医]异或[医]显式
| Defined in header | | |
|---|---|---|
| | (1) | (since C++11) |
| template< class Integral > Integral atomic_fetch_xor( std::atomic<Integral>* obj, Integral arg | | |
| template< class Integral > Integral atomic_fetch_xor( volatile std::atomic<Integral>* obj, Integral arg | | |
| | (2) | (since C++11) |
| template< class Integral > Integral atomic_fetch_xor_explicit( std::atomic<Integral>* obj, Integral arg, std::memory_order order | | |
| template< class Integral > Integral atomic_fetch_xor_explicit( volatile std::atomic<Integral>* obj, Integral arg, std::memory_order order | |
原子地替换obj的旧值之间的按位异或的结果。obj和arg返回值obj以前持有。
执行该操作时，就好像执行了以下操作一样：
1%29obj->fetch_xor(arg)
2%29obj->fetch_xor(arg, order)
参数
| obj | - | pointer to the atomic object to modify |
|---|---|---|
| arg | - | the value to bitwise XOR to the value stored in the atomic object |
| order | - | the memory sycnhronization ordering for this operation: all values are permitted. |
返回值
中此函数的效果之前的值。修改顺序成*obj...
例外
noexcept规格：

| fetch_xor | atomically performs bitwise XOR between the argument and the value of the atomic object and obtains the value held previously (public member function of std::atomic) |
|---|---|
| atomic_fetch_oratomic_fetch_or_explicit (C++11)(C++11) | replaces the atomic object with the result of logical OR with a non-atomic argument and obtains the previous value of the atomic (function template) |
| atomic_fetch_andatomic_fetch_and_explicit (C++11)(C++11) | replaces the atomic object with the result of logical AND with a non-atomic argument and obtains the previous value of the atomic (function template) |
