std::atomic_ref::fetch_or(3)

💅 std::atomic_ref::fetch_or(3) 💅

okay so bestie, welcome to the manual page for std::atomic_ref::fetch_or, straight outta the C++ Standard Libary (yes, that spelling is doing its own thing 😭). it's giving atomic-OR main character energy, and we're gonna get you comfy with it. no cap.

🌸 NAME 🌸

std::atomic_ref::fetch_or - std::atomic_ref::fetch_or

🦋 Synopsis 🦋

member only of atomic_ref<Integral> specializations

T fetch_or( T arg,
            std::memory_order order = std::memory_order_seq_cst )

(since C++20)

const noexcept;

so what's the tea? it atomically replaces the current value of the referenced object with the result of bitwise OR of the value and arg. this operation is a read-modify-write operation, periodt. memory is affected according to the value of order. ✨

💖 Parameters 💖

• arg — the other argument of bitwise OR. literally the other side of the OR moment 🫶
• order — memory order constraints to enforce. the vibe check for memory ordering 💅

✨ Return value ✨

the value of the referenced object, immediately preceding the effects of this function. iykyk — it's the value from right before this function did its thing 😭

cute sign-off, bestie: source/version/date = http://cppreference.com · 2024.06.10 🎀 mwah 💋
