raw_atomic_long_xor(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so bestie, meet raw_atomic_long_xor from the Kernel API Manual — it's the atomic bitwise XOR with relaxed ordering situation. Very demure, very atomic, very relaxed. 💖

✨ SYNOPSIS ✨

void raw_atomic_long_xor (long i , atomic_long_t *v );

🌸 ARGUMENTS 🌸

  • i — a long value. This is the XOR buddy. 🫶
  • v — pointer to atomic_long_t. This is the thing getting updated. 👑

🦋 DESCRIPTION 🦋

Atomically updates v to (v ^ i) with relaxed ordering. That's the whole plot, no cap. 🎀

Safety note straight from the page: this is safe to use in noinstr code; prefer atomic_long_xor elsewhere. iykyk 💅

🍓 RETURN 🍓

Nothing. Not 0, not a little success token, literally nothing. 😭🫶
