✨ ubi_change_vtbl_record — bestie's guide to editing the volume table 💅

okay so this one lives in the Kernel API Manual, section 9, and honestly? it's a little cutie once you get to know her. 🎀

🌸 NAME 🌸

ubi_change_vtbl_record — change volume table record. that's it, that's the whole vibe. she edits one record and dips. ✨

---

🦋 SYNOPSIS 🦋

int ubi_change_vtbl_record(struct ubi_device *ubi, int idx,
                           struct ubi_vtbl_record *vtbl_rec);

---

💖 ARGUMENTS 💖

• ubi — the UBI device description object. like, the whole device's lil info bundle, main character energy fr. 👑
• idx — the table index to change. you're telling her which record she's touching, bestie. no guessing. ��
• vtbl_rec — the new volume table record. this is the new content that goes in. 🫶

---

🔥 DESCRIPTION 🔥

so here's the tea: this function changes volume table record idx. 🍓

and like — important part — if vtbl_rec is NULL, an empty volume table record is written instead. so passing NULL is a real, intentional move, not a mistake. lowkey elegant ngl. 💜

the caller does not have to calculate the CRC of the record, because this function does it for you. she handles the CRC herself, bestie, you don't gotta lift a finger. 🧚✨

returns zero in case of success and a negative error code in case of failure. standard slay. 🌈
