raw_atomic_l...tive_relaxed(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

raw_atomic_long_add_negative_relaxed — atomic add and test if negative with relaxed ordering. That’s the function, bestie, and she’s literally doing exactly what it says on the tin 💅

🛠️ SYNOPSIS 🛠️

okay so the whole call looks like this, character for character:

bool raw_atomic_long_add_negative_relaxed (long i , atomic_long_t *v );

🎀 ARGUMENTS 🎀

two little params, no cap:

  • i — long value to add. this is the number you’re adding in, and yes she’s a long.
  • v — pointer to atomic_long_t. this is the atomic long you’re updating, passed as a pointer 🫶

💅 DESCRIPTION 💅

okay so the actual behavior: it atomically updates v to (v + i) with relaxed ordering. that’s the whole plot, fr fr 💖

also, important caveat bestie: this one is safe to use in noinstr code. everywhere else, prefer atomic_long_add_negative_relaxed — like, she’s the one you want in normal-land. no cap ✨

🔥 RETURN 🔥

it returns true if the resulting value of v is negative, and false otherwise. so you get your little “did this end up negative?” answer. iconic 🔥
