ubifs_read_nnode(9)

💫 ubifs_read_nnode(9) 💫

okay bestie, so this little page comes straight out of the Kernel API Manual, and it's literally about pulling a nnode off the flash and hooking it into the tree in memory. yes, that's the whole vibe. 🦋

---

✨ NAME ✨

ubifs_read_nnode — read a nnode from flash and link it to the tree in memory.

like, that's the job. that's the assignment. and it ate. 💅

---

🌸 SYNOPSIS 🌸

int ubifs_read_nnode (struct ubifs_info *c , struct ubifs_nnode *parent
, int iip );

okay so it returns an int, and it takes three things. keep scrolling, i got you 🫶

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. yes, the main character of the whole file system. 🌟
• parent — the parent nnode. and ngl, this one can be NULL for the root 👑 (root nnode has no parent, she's independent like that).
• iip — the index in the parent. where you at bestie, positional info, ikyk. 🔍

---

💖 DESCRIPTION 💖

okay so real talk: this function returns 0 on success, and a negative error code on failure. that's it. no cap, no plot twist, just a clean return value. if you see a negative number, something went sideways 😭 — if you see 0, we slay. ✨
