mtd_ooblayout_set_eccbytes(9)

🎀 NAME 🎀

hey bestie, welcome to mtd_ooblayout_set_eccbytes(9) from the Kernel API Manual 💖 — and yes, it’s literally giving “set ECC bytes into the oob buffer” energy. ✨

---

✨ SYNOPSIS ✨

okay so here’s the signature, copy-paste-ready and exactly as it appears:

int mtd_ooblayout_set_eccbytes (struct mtd_info *mtd , const u8 *eccbuf
, u8 *oobbuf , int start , int nbytes );

---

🌸 ARGUMENTS 🌸

• mtd — the mtd info structure, aka the context bestie / main character of this call 👑
• eccbuf — source buffer to get ECC bytes from 🍓
• oobbuf — the OOB buffer, periodt 💅
• start — first ECC byte to set, iykyk
• nbytes — number of ECC bytes to set — like, how many little guys we’re moving 🧚

---

🦋 DESCRIPTION 🦋

okay so it works like mtd_ooblayout_set_bytes, except it acts on ECC bytes — that’s the whole vibe, no cap. 💜

Returns zero on success, a negative error code otherwise. so: zero = slay ✅, negative error code = not the moment 😭.
