NAME¶

std::latch::try_wait - std::latch::try_wait

Synopsis¶

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

Returns true only if the internal counter has reached zero. This function may
spuriously return false with very low probability even if the internal counter has
reached zero.

Parameters¶

(none)

Return value¶

With very low probability false, otherwise cnt == 0, where cnt is the value of the
internal counter.

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.
