nand_do_read_oob(9)

✨ nand_do_read_oob(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel kernel, we're in the big leagues now 💅 — and it's all about nand_do_read_oob, like, the function literally named "do read out-of-band" because subtlety is not its vibe 🎀

---

🌸 NAME 🌸

nand_do_read_oob — [INTERN] NAND read out-of-band

[INTERN] means it's an internal thing, bestie. Not your average public API — it's giving backstage-pass energy 🎟️

---

✨ SYNOPSIS ✨

int nand_do_read_oob (struct nand_chip *chip , loff_t from , struct
       mtd_oob_ops *ops );

so it returns an int, takes three things, and yes it stays up all night doing NAND things 😭

---

🫶 ARGUMENTS 🫶

• chip — the NAND chip object. like, the actual chip. your main character 👕
• from — the offset to read from. where we're starting, iykyk 📍
• ops — the oob operations description structure. this is the little briefing doc telling us what we're doing 🗂️

---

🦋 DESCRIPTION 🦋

NAND read out-of-band data from the spare area. that's it, that's the whole vibe — we're grabbing the out-of-band data out of the spare area, and honestly? obsessed 💖

🌈 SEE ALSO 🌈

okay this list is long long, so buckle up bestie, we're going through all of it, no skipping, periodt 👑
