raw_atomic_long_read(9)

💖 raw_atomic_long_read(9) — Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual page for raw_atomic_long_read(9). This is the raw, relaxed-order atomic-load girlie. She's lowkey iconic and very specific about the vibe. ✨

---

🌸 NAME 🌸

raw_atomic_long_read — atomic load with relaxed ordering 💅

✨ SYNOPSIS ✨

long raw_atomic_long_read (const atomic_long_t *v );

🎀 ARGUMENTS 🎀

• v — pointer to atomic_long_t. That's it. That's the whole argument. 🫶

💅 DESCRIPTION 💅

So like, raw_atomic_long_read atomically loads the value of v with relaxed ordering. No cap. It's literally the raw atomic long read.

It's safe to use in noinstr code; prefer atomic_long_read elsewhere. Yes bestie, that “elsewhere” is doing a lot of work — don't make raw_atomic_long_read your default main character unless you're in the noinstr zone. 💀

Vibe check: the page says safe in noinstr code and prefer atomic_long_read elsewhere. Keep that energy. 🫡

🦋 RETURN 🦋

It returns the value loaded from v. Periodt. 💖
