atomic_long_set_release(9)

📦 version 7.3.1, in nixpkgs unstable

💅 atomic_long_set_release(9)

okay so this is atomic_long_set_release(9), straight out of the Kernel API Manual, and bestie… it's a whole vibe. it's small, it's mighty, it's giving "one job and she does it flawlessly." let's get into it 🫶

🌸 NAME

atomic_long_set_release — an atomic set, but make it release-ordered ✨

✨ SYNOPSIS

void atomic_long_set_release (atomic_long_t *v , long i );

🎀 ARGUMENTS

  • v — pointer to atomic_long_t. this is the thing you're writing into, she's the main character 💅
  • i — the long value you're assigning. this is what goes in 👑

💖 DESCRIPTION

so basically: this atomically sets v to i, with release ordering. that's it, that's the whole slay. one write, atomically, with the ordering semantics handled for you 🌈

⚠️ real talk though — this is unsafe to use in noinstr code. if you're in noinstr land, use raw_atomic_long_set_release there instead. no cap, don't skip this one 💀

🦋 RETURN

Nothing. literally nothing. she does the thing and leaves, no receipts, no follow-up, periodt 💜

and now… the entire friend group 😭 like genuinely the whole cast, buckle up:

and the 64-bit side of the family 💫

and finally the long besties — aka OUR GIRL's home squad 👑🔥

and that's the whole roster, bestie, we got through it together 🫶 iykyk 💖
