STD：：原子：：获取[医]异或
| | | (since C++11) (member only of atomic |
|---|---|---|
| T fetch_xor( T arg, std::memory_order order = std::memory_order_seq_cst | | |
| T fetch_xor( T arg, std::memory_order order = std::memory_order_seq_cst ) volatile; | | |
原子化地用值的按位异或的结果替换当前值arg.操作是读-修改-写操作.。的值影响内存。order...
参数
| arg | - | the other argument of bitwise XOR |
|---|---|---|
| order | - | memory order constraints to enforce |
返回值
中此函数的效果之前的值。修改顺序成*this...
