raw_atomic64_and(9)

📦 version 7.3.1, in nixpkgs unstable

raw_atomic64_and(9) — pulled straight from the Kernel API Manual, and yes bestie we’re getting into it 💅

✨ NAME ✨

raw_atomic64_and — atomic bitwise AND with relaxed ordering

🌸 SYNOPSIS 🌸

void raw_atomic64_and (s64 i , atomic64_t *v );

🎀 ARGUMENTS 🎀

  • i — an s64 value. That’s the value, bestie.
  • v — pointer to atomic64_t. That’s the atomic thing getting updated.

💫 DESCRIPTION 💫

Atomically updates v to (v & i) with relaxed ordering.

Safe to use in noinstr code; prefer atomic64_and elsewhere.

lowkey important: this one is the raw atomic64 version, and the ordering is relaxed. Also, noinstr code can use it; everywhere else, the page says prefer atomic64_and.

🫶 RETURN 🫶

Nothing. Not a value, not a vibe, literally nothing.
