std::experi...:count_down(3)

💖 std::experimental::latch::count_down 💖

okay so bestie, vibe check: this is the manual page std::experi...:count_down(3) from the C++ Standard Libary manual — yes, that’s the exact manual name on the page, typo and all 😭✨.

🎀 NAME 🎀

• std::experimental::latch::count_down — std::experimental::latch::count_down

✨ Synopsis ✨

void count_down( ptrdiff_t n = 1 ); (1) (concurrency TS)

It atomically decrements the internal counter by n without blocking the caller. Slay, but make it atomic 💅.

⚠️ If n is greater than the value of the internal counter or is negative, the behavior is undefined. That’s the dangerous little gremlin clause, bestie — respect it 🫶.

This operation synchronizes with all calls that block on this latch and all is_ready calls on this latch that returns true. yep, that’s the exact sync tea ☕✨.

🌸 Parameters 🌸

• n — the value by which the internal counter is decreased.

🦋 Return value 🦋

• (none) — literally nothing comes back, bestie. No return value, no cap.

💀 Exceptions 💀

Throws nothing. not even a tiny dramatic throw 😌.
