std::atomic_ref<T>::operator&=,|=,^=

Atomically replaces the current value of the referenced object with the result of computation involving the previous value and arg. These operations are read-modify-write operations.

# Declarations

Provided only when T is an integral type other than cv bool

value_type operator&=( value_type arg ) const noexcept;

(since C++20)

value_type operator|=( value_type arg ) const noexcept;

(since C++20)

value_type operator^=( value_type arg ) const noexcept;

(since C++20)

# Parameters

• arg: the argument for the arithmetic operation

# Return value

The resulting value (that is, the result of applying the corresponding binary operator to the value immediately preceding the effects of the corresponding member function).

# Notes

Unlike most compound assignment operators, the compound assignment operators for atomic_ref do not return a reference to their left-hand arguments. They return a copy of the stored value instead.
