ubifs_copy_hash(9)

💖 ubifs_copy_hash(9) 💖

okay so bestie, welcome to the Kernel API Manual page for ubifs_copy_hash(9) — yes the manual name is literally in the title, we're not subtle here 😌

---

✨ NAME ✨

ubifs_copy_hash — it copies a hash. that's it. that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

void ubifs_copy_hash (const struct ubifs_info *c , const u8 *from , u8 *to );

like, look at her. void return, three args, no notes. icon behavior 💅

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. she's the context, the main character, the one who knows everything 🫶
• from — source hash. where the hash is coming from, iykyk 💖
• to — destination hash. where it's going. the glow-up location ✨

---

💜 DESCRIPTION 💜

so here's the tea ☕ — with authentication, this copies a hash. without authentication? it literally does nothing. not me describing a function that lowkey ghosts you when auth is off 😭💀
