std::atomic::fetch_xor

From cppreference.com
< cpp‎ | atomic‎ | atomic
 
 
 
 
(since C++11)
(member only of atomic<Integral> template specialization)
T fetch_xor( T arg,
             memory_order = std::memory_order_seq_cst );
T fetch_xor( T arg,
             memory_order = std::memory_order_seq_cst ) volatile;

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 memory_order.

[edit] Parameters

arg - the other argument of bitwise XOR
