ubifs_get_nnode(9)

✨ ubifs_get_nnode(9) ✨

okay so we're in the Kernel API Manual, section 9, and today's main character is ubifs_get_nnode — literally the function that gets you a nnode. that's it, that's the vibe. 🎀

---

🌸 NAME 🌸

ubifs_get_nnode — get a nnode.

periodt. no notes.

---

💫 SYNOPSIS 💫

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

---

🫶 ARGUMENTS 🫶

• c — the UBIFS file-system description object. yes bestie, the whole file system, right there in one struct 💅
• parent — the parent nnode. or NULL for the root — so if you're passing NULL, congrats, you're at the top of the tree, main character energy fr fr 👑
• iip — index in parent. which slot you're grabbing, iykyk

---

🦋 DESCRIPTION 🦋

so this function returns a pointer to the nnode on success, or a negative error code on failure. that's the whole plot 🍓

lowkey important: check that return value. pointer = slay, negative error code = not slay. don't mix them up bestie 😭
