NAME¶

std::atomic_ref::notify_all - std::atomic_ref::notify_all

Synopsis¶

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

Performs atomic notifying operations.

Unblocks all threads blocked in atomic waiting operations (i.e. wait()) on *this, if
there are any; otherwise does nothing.

Return value¶

(none)

Notes¶

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