💅 yama_task_prctl(9) — like, the Kernel API Manual edition ✨

okay so bestie, welcome to yama_task_prctl 🎀 this is one of those little functions living in the Kernel API Manual and she's here to do exactly one job: check for Yama-specific prctl operations. no cap, that's the whole vibe. 🦋

✨ NAME ✨

yama_task_prctl — check for Yama-specific prctl operations 👑

🌸 SYNOPSIS 🌸

int yama_task_prctl (int option , unsigned long arg2 , unsigned long
       arg3 , unsigned long arg4 , unsigned long arg5 );

🫶 ARGUMENTS 🫶

• option — the operation, i.e. which thing we're being asked about 💫
• arg2 — argument 👀
• arg3 — argument 👀
• arg4 — argument 👀
• arg5 — argument 👀

(yeah, arg2 through arg5 are literally just "argument" in the original and we are not out here inventing lore, bestie 🙈)

💜 DESCRIPTION 💜

So here's the tea ☕ — this one returns 0 on success, and -ve on error. that's it, that's the contract. 💀

And the icon -ENOSYS shows up when Yama doesn't handle the given option — like, not her department, not her problem, moving on. 💅 slay.
