create_vtbl(9)

💅 create_vtbl — kernel API manual, but make it cute 🎀

okay so bestie, welcome to create_vtbl(9) from the Kernel API Manual — yes that Kernel API Manual, the one we all fear and love. this is a function page, it's short, it's sweet, and it's giving "small but crucial" energy. let's get into it ✨

---

🌸 NAME 🌸

create_vtbl — literally makes a copy of the volume table. that's it, that's the function. lowkey iconic for how straightforward it is 🦋

---

✨ SYNOPSIS ✨

int create_vtbl (struct ubi_device *ubi , struct ubi_attach_info *ai ,
int copy , void *vtbl );

here's the vibe: it takes four things and returns an int, no cap. the weird spacing in the original? keeping it exactly, because that's how it's written and we respect the source fr fr 💅

🫶 ARGUMENTS 🫶

• ubi — your UBI device description object. this is the main character, the device itself, the whole reason we're here 👑
• ai — attaching information. the lore you need before you can attach, basically 🌈
• copy — the number of the volume table copy. which copy? this number decides. not me being picky about copies 😭
• vtbl — the contents of the volume table. this is the payload, the actual table data, the whole snack 🍓

---

💖 DESCRIPTION 💖

so what does it do? it creates a copy of the volume table, and then it tells you how it went.

• returns zero in case of success — slay, we love a clean 0 ✨
• returns a negative error code in case of failure — so if the return value is negative, something went wrong, and the number tells you what 🙈

that's literally the whole description. no hidden clauses, no fine print. honestly? refreshing. ate and left no crumbs 💀
