🎀 get_exclusive(9) 🎀

okay bestie, welcome to the Kernel API Manual 💅 — yes, that's the manual name, and yes, we're doing this. today's main character is get_exclusive, and by the end of this page you're gonna understand it so well it's giving study date energy 🫶

✨ NAME ✨

get_exclusive — get exclusive access to an UBI volume. that's it, that's the whole vibe. lowkey iconic for how much it does with so few words 🦋

---

🌸 SYNOPSIS 🌸

int get_exclusive (struct ubi_volume_desc *desc );

literally copy that exactly, character for character, no cap — spacing and all 😭

---

💖 ARGUMENTS 💖

• desc — the volume descriptor. that's your little handle-ticket to the volume, and it's what you're handing over so the function knows which volume is about to become the volume 👑

---

⭐ DESCRIPTION ⭐

so here's the tea, bestie 🍓 — this function changes the UBI volume open mode to "exclusive". meaning your volume gets that main character energy and nobody else gets to play in it. slay.

and it doesn't just silently do it — it reports back! it returns the previous mode value (a positive integer) in case of success, and a negative error code in case of failure. so success = you get receipts of what the mode used to be, failure = a negative number and a little 💀 moment.

no guessing games here: positive integer means it worked and here's the old mode, negative means it didn't. periodt.
