原子取代的
3-4) arg
岁之间的值按位异或的结果所指向的数值obj
arg
,并返回值obj
举行之前,如果由obj->fetch_and(arg)原文:
Atomically replaces the value pointed by
arg
with the result of bitwise XOR between the old value of obj
and arg
, and returns the value obj
held previously, as if by obj->fetch_and(arg)原子取代的
arg
岁之间的值按位异或的结果所指向的数值obj
arg
,并返回值obj
举行之前,如果由obj->fetch_and(arg, order)原文:
Atomically replaces the value pointed by
arg
with the result of bitwise XOR between the old value of obj
and arg
, and returns the value obj
held previously, as if by obj->fetch_and(arg, order)目录 |
[编辑] 参数
obj | - | 指针的原子对象修改
原文: pointer to the atomic object to modify |
arg | - | 值的原子对象中存储的值按位异或
原文: the value to bitwise XOR to the value stored in the atomic object |
order | - | 的的内存sycnhronization订购此操作:所有的允许值.
原文: the memory sycnhronization ordering for this operation: all values are permitted. |
[编辑] 返回值
以前保存的值的原子对象所指向的
obj
原文:
The value held previously by the atomic object pointed to by
obj
[编辑] 例外
[编辑] 可能的实现
template< class T > typename std::enable_if<std::is_integral<T>::value && !std::is_same<T, bool>::value, T>::type atomic_fetch_xor( std::atomic<T>* obj, T arg ); { return obj->fetch_xor(arg); } |
