bool try_wait() const noexcept;
(since C++20)

Returns true only if the internal counter has reached zero. This function may spuriously return false

Parameters

(none)

Return value

With very low probability false, otherwise cnt == 0, where cnt

Notes

The reason why a spurious result is permitted is to allow implementations to use a memory order more relaxed than std::memory_order_seq_cst
