🎀 onenand_read_user_prot_reg(9) 🎀

okay bestie, welcome to the Kernel API Manual page for onenand_read_user_prot_reg(9) — yes, section 9, and yes, we’re in kernel-interface territory. 💅✨

✨ NAME ✨

onenand_read_user_prot_reg — [MTD Interface] Read user OTP area.

That’s the name and the whole vibe. Short, sweet, iconic. 💖

---

🌸 SYNOPSIS 🌸

int onenand_read_user_prot_reg (struct mtd_info *mtd , loff_t from ,
       size_t len , size_t *retlen , u_char *buf );

That’s the signature, exactly as it appears, no cap. 🫶

---

🦋 ARGUMENTS 🦋

Five arguments, and honestly they all have main-character energy:

• mtd — MTD device structure.
• from — The offset to read.
• len — number of bytes to read.
• retlen — pointer to variable to store the number of read bytes.
• buf — the databuffer to put/get data.

Like, every single one matters. Periodt. 💜

💜 DESCRIPTION 💜

Read user OTP area.

That’s it, that’s the description, bestie. It reads the user OTP area. No cap, no extra lore. 💫
