std::counti...g_semaphore(3)

okay bestie, welcome to the C++ Standard Libary manual page for std::counti...g_semaphore(3) — aka the std::counting_semaphore destructor page. It’s giving tiny page, huge “do not touch me while I’m destructing” energy. 🦋✨

💖 NAME 💖

• std::counting_semaphore::~counting_semaphore — the destructor, and the description is literally std::counting_semaphore::~counting_semaphore too. Repetition is the brand. 💅

🦋 Synopsis 🦋

~counting_semaphore();  (since C++20)

This destructor destroys the counting_semaphore object. Periodt. 🎀

⚠️ UB ALERT, bestie: the behavior is undefined if any thread is concurrently calling any other member function on this semaphore. This includes threads blocked in acquire(), try_acquire_for(), or try_acquire_until(). So like… do not have another thread in there doing member-function things while this destructor is running. That’s the whole warning. 😭💀

okay that’s the page, bestie. 🫶 It came from http://cppreference.com and is dated 2024.06.10. slay and destruct safely. 💅✨
