std::atomic<T>::fetch_xor
From cppreference.com
member only of atomic<Integral > specializations |

T fetch_xor( T arg, std::memory_order order = std::memory_order_seq_cst ) noexcept; |
(1) | (since C++11) |
T fetch_xor( T arg, std::memory_order order = std::memory_order_seq_cst ) volatile noexcept; |
(2) | (since C++11) |
Atomically replaces the current value with the result of bitwise XOR of the value and arg. The operation is read-modify-write operation. Memory is affected according to the value of order.
It is deprecated if std::atomic<T>::is_always_lock_free is false and overload (2) participates in overload resolution. |
(since C++20) |
[edit] Parameters
arg | - | the other argument of bitwise XOR |
order | - | memory order constraints to enforce |
[edit] Return value
The value immediately preceding the effects of this function in the modification order of *this.
