ubi_find_av(9)

✨ ubi_find_av(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for ubi_find_av — yes that's the function name and yes we're gonna get into it 💅

---

🌸 NAME 🌸

ubi_find_av — literally just finds a volume in the attaching information. that's it. that's the whole gig 🎀

---

🦋 SYNOPSIS 🦋

struct ubi_ainf_volume * ubi_find_av (const struct ubi_attach_info *ai ,
int vol_id );

---

💖 ARGUMENTS 💖

• ai — the attaching information. yeah. that's the thing you're looking through 👀
• vol_id — the volume ID you're asking for. the one you want. the requested one, if you will ✨

---

🌈 DESCRIPTION 🌈

so here's the vibe: this function hands you back a pointer to the volume description. that's the win. that's the moment 🫶

but plot twist — if there's no data about this volume in the attaching information, you get NULL. no data, no pointer, no volume, bye 💀 that's the whole contract, no cap.
