dent_key_init_hash(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dent_key_init_hash(9) — from the Kernel API Manual, bestie

okay so you're in the UBIFS key corner of the kernel and you need a directory entry key, but you already have the hash and you are NOT about to sit there recalculating it like some kind of clown 😤 That's literally this function. It initializes a directory entry key without re-calculating the hash function. No cap. 🎀

✨ SYNOPSIS ✨

void dent_key_init_hash (const struct ubifs_info *c , union ubifs_key
*key , ino_t inum , uint32_t hash );

like, it returns void — nothing comes back, it just fills in your key and vibes. 🦋

🌸 ARGUMENTS 🌸

  • c — the UBIFS file-system description object. your whole filesystem's little passport, basically 🛂
  • key — the key you're initializing. the main character, the one getting filled in 👑
  • inum — the parent inode number 🧬
  • hash — the direntry name hash. yes, the one you already have. that's the whole point, iykyk 💅
