trun_key_init(9)

🦋 trun_key_init(9) 🦋

okay so we're in the Kernel API Manual, and the main character of this page is trun_key_init — initialize truncation node key. It's a tiny little helper, but she's iconic for replay, iykyk. 💅

🌸 NAME 🌸

trun_key_init - initialize truncation node key.

✨ SYNOPSIS ✨

void trun_key_init (const struct ubifs_info *c , union ubifs_key *key ,
ino_t inum );

the return type is void — literally no value comes back, bestie — and you're handing over three things. slay. 🫶

🎀 ARGUMENTS 🎀

• c — UBIFS file-system description object.
• key — key to initialize.
• inum — inode number.

💅 DESCRIPTION 💅

⚠️ Note, UBIFS does not have truncation keys on the media — like, none, not a single one — and this function is only used for purposes of replay. That's the whole point, fr fr. 💖
