ubifs_tnc_add(9)

💖 ubifs_tnc_add(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, the whole manual, and yes we're reading it together, it's fine, it's gonna slay 🫶

---

✨ NAME ✨

ubifs_tnc_add — add a node to TNC. that's it, that's the whole vibe. a node. into the TNC. 💅

---

🌸 SYNOPSIS 🌸

int ubifs_tnc_add (struct ubifs_info *c , const union ubifs_key *key ,
int lnum , int offs , int len , const u8 *hash );

like look at her. she's a function. she returns an int. she's iconic. ✨

---

🎀 ARGUMENTS 🎀

one bullet per bestie, no skipping, periodt:

• c — the UBIFS file-system description object. literally the whole file system's whole personality in one struct.
• key — the key to add. the main character of this operation, ngl.
• lnum — the LEB number of the node. which LEB. you know the one.
• offs — the node offset. where in the thing she lives.
• len — the node length. how much node there is.
• hash — the hash over the node. the node's little fingerprint, 🫶.

---

🦋 DESCRIPTION 🦋

okay so here's the tea, bestie: this function adds a node with key key to the TNC. 💖

and like — plot twist — the node may be brand new, or it may obsolete some existing one. both are valid. she contains multitudes. no cap.

she returns 0 on success, or a negative error code on failure. that's the whole contract. that's the deal. 🙈

ngl bestie, that SEE ALSO list is giving main character energy and also mildly giving "final boss of cross-references". respect it. 👑
