hey bestie!! welcome to the Library Functions Manual page for std::atomic_flag ✨ this is the whole vibe, no cap.

✨ NAME ✨

std::atomic_flag — atomic_flag

🌸 SYNOPSIS 🌸

#include <atomic>

💅 Public Member Functions 💅

okay so here's the full roster, every single one, periodt:

  • constexpr atomic_flag (bool __i) noexcept — the constexpr constructor that takes a bool __i and is noexcept 🫶
  • atomic_flag (const atomic_flag &)=delete — copy constructor? deleted. not invited to the party 💀
  • void clear (memory_order __m=memory_order_seq_cst) noexcept — clears it, with memory_order __m defaulting to memory_order_seq_cst, and it's noexcept 🧚
  • void clear (memory_order __m=memory_order_seq_cst) volatile noexcept — same clear, but the volatile flavor, same default memory_order_seq_cst, still noexcept ✨
  • atomic_flag & operator= (const atomic_flag &) volatile =delete — volatile assignment operator, deleted. nope 🙈
  • atomic_flag & operator= (const atomic_flag &)=delete — regular assignment operator, also deleted. double nope 💅
  • bool test (memory_order __m=memory_order_seq_cst) const noexcept — tests it, takes memory_order __m=memory_order_seq_cst, const, noexcept, returns bool 🔥
  • bool test (memory_order __m=memory_order_seq_cst) const volatile noexcept — the const volatile test, same default memory_order_seq_cst, noexcept, returns bool 🌈
  • bool test_and_set (memory_order __m=memory_order_seq_cst) noexcept — test and set, memory_order __m=memory_order_seq_cst, noexcept, returns bool ⭐
  • bool test_and_set (memory_order __m=memory_order_seq_cst) volatile noexcept — the volatile test and set, same default memory_order_seq_cst, noexcept, returns bool 👑

🦋 Detailed Description 🦋

atomic_flag

that's literally it. the whole detailed description. iconic minimalism, honestly 😭

and that's the page, bestie!! footer says libstdc++ and it's the std::atomic_flag(3) manual page — no date on this one, just that source/version energy. bye, ily, go atomically flag something 💖🦋✨
