NAME¶

std::atomic_ref::notify_one - std::atomic_ref::notify_one

Synopsis¶

void notify_one() const noexcept; (1) (since C++20)
void notify_one() const volatile noexcept; (2) (since C++20)

Performs atomic notifying operations.

If there is a thread blocked in atomic waiting operation (i.e. wait()) on *this,
then unblocks at least one such thread; otherwise does nothing.

Return value¶

(none)

Notes¶

This form of change-detection is often more efficient than simple polling or pure
spinlocks.
