Atomically replaces the value pointed by arg
with the result of bitwise XOR between the old value of obj
and arg
. Returns the value obj
held previously.
The operation is performed as if the following is executed:
1) obj->fetch_xor(arg)
2) obj->fetch_xor(arg, order)

[edit] Parameters
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. |
[edit] Return value
The value immediately preceding the effects of this function in the modification order of *obj
.
[edit] Exceptions
noexcept specification:

[edit] Possible implementation
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); } |
