queued_write_trylock(9)

📦 version 7.3.1, in nixpkgs unstable

💅 queued_write_trylock — the manual page bestie 💅

okay so real talk, we're in the Kernel API Manual today and the main character is queued_write_trylock. she's a little function with big "try to acquire write lock of a queued rwlock" energy, and honestly? iconic. no cap, this is the whole vibe. 🦋

✨ SYNOPSIS ✨

int queued_write_trylock (struct qrwlock *lock );

like, that's literally the whole signature. short king behavior fr fr 👑

🎀 ARGUMENTS 🎀

  • lock — pointer to the queued rwlock structure. that's it, that's the one (1) argument. she takes a pointer, she don't take notes. 💅

🌸 RETURN 🌸

  • 1 — yasss, lock acquired, you ate that 💖
  • 0 — nope, failed, better luck next time bestie 😭
not me emphasizing that it literally returns 1 if the lock was acquired and 0 if it failed — because that's lowkey the whole point and I need you to remember it. 🫶

🦋 SEE ALSO 🦋
