get_cs_sqnum(9)

✨ get_cs_sqnum(9) ✨

okay so bestie, welcome to get_cs_sqnum from the Kernel API Manual — yes, get_cs_sqnum(9), the little guy whose whole personality is grabbing a commit start sequence number for you 💅 no cap, that's the entire NAME section, she's short but she's iconic.

---

🎀 SYNOPSIS 🎀

int get_cs_sqnum (struct ubifs_info *c , int lnum , int offs , unsigned
long long *cs_sqnum );

literally that's the whole signature, copy it exactly, don't @ me 🫶

---

🌸 ARGUMENTS 🌸

• c — the UBIFS file-system description object, aka the main character of this whole situation 👑
• lnum — LEB number of the commit start node, like the address of the vibe
• offs — offset of the commit start node, aka where inside that LEB we're looking 🎯
• cs_sqnum — the commit start sequence number gets returned here, so this is the output spot, she's the drop-off point 🍓

---

💖 DESCRIPTION 💖

so here's the tea ☕ this function returns 0 on success, and a negative error code on failure. that's it. that's the description. short and sweet, like a text from your bestie at 3am 🌙✨

ngl bestie, if you see a negative number come back you did not slay — that's the failure branch, handle it 🙈
