self_check_volume(9)

✨ NAME ✨

self_check_volume — bestie, this one literally just checks volume information 💅 no cap, that's the whole job.

Oh and hi, welcome to the Kernel API Manual 🎀 you're gonna do great here.

---

🌸 SYNOPSIS 🌸

int self_check_volume (struct ubi_device *ubi , int vol_id );

That's the whole signature, periodt. ✨

---

🎀 ARGUMENTS 🎀

• ubi — the UBI device description object 🫶 like, the whole device's little info card.
• vol_id — the volume ID 👑 which volume we're vibing with.

---

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕ — self_check_volume returns zero if the volume is all right, and if it's not all right you get a negative error code back instead. That's it. That's the function. Simple, iconic, no drama. 💖

Heads up bestie: zero = good vibes, negative = something's off. Don't flip those in your head, iykyk 😭
