NAME
std::atomic_fetch_xor,std::atomic_fetch_xor_explicit - std::atomic_fetch_xor,std::atomic_fetch_xor_explicit

Synopsis
   Defined in header <atomic>
   template< class T >
   T atomic_fetch_xor( std::atomic<T>* obj, (1) (since C++11)
                       typename std::atomic<T>::value_type arg )
   noexcept;
   template< class T >
   T atomic_fetch_xor( volatile std::atomic<T>* obj, (2) (since C++11)
                       typename std::atomic<T>::value_type arg )
   noexcept;
   template< class T >
   T atomic_fetch_xor_explicit( std::atomic<T>* obj,
                        typename std::atomic<T>::value_type (3) (since C++11)
   arg,
                        std::memory_order order) noexcept;
   template< class T >
   T atomic_fetch_xor_explicit( volatile std::atomic<T>* obj,
                        typename std::atomic<T>::value_type (4) (since C++11)
   arg,
                        std::memory_order order) noexcept;
   Atomically replaces the value pointed by obj 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:
   1,2) obj->fetch_xor(arg)
   3,4) obj->fetch_xor(arg, order)
   If std::atomic<T> has no fetch_xor member (this member is only provided for integral
   types except bool), the program is ill-formed.

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 synchronization ordering

Return value
   The value immediately preceding the effects of this function in the modification
   order of *obj.

   Defect reports
   The following behavior-changing defect reports were applied retroactively to
   previously published C++ standards.
     DR Applied to Behavior as published Correct behavior
   P0558R1 C++11 exact type match was required because T is only deduced
                      T was deduced from multiple arguments from obj
