nanddev_offs_to_pos(9)

💅 nanddev_offs_to_pos(9) — like, the kernel API manual, but make it make sense

okay so bestie, this is a page from the Kernel API Manual, and today's main character is nanddev_offs_to_pos. no cap, it's a tiny little helper and it absolutely ate. let's get into it 🫶

---

✨ NAME ✨

nanddev_offs_to_pos — convert an absolute NAND offset into a NAND position 🌸

like, you hand it a number, it hands you a place. it's giving GPS for flash memory, literally.

---

🎀 SYNOPSIS 🎀

unsigned int nanddev_offs_to_pos (struct nand_device *nand , loff_t offs
, struct nand_pos *pos );

that's the whole vibe. three args, one return value, no drama 💜

---

🦋 ARGUMENTS 🦋

• nand — the NAND device 💖 like, the actual chip situation we're talking about here
• offs — the absolute NAND offset, and ngl it's usually passed by the MTD layer (so you probably didn't even type it yourself)
• pos — a NAND position object that this function fills in ✨ you bring the empty container, it brings the contents

---

🌈 DESCRIPTION 🌈

so what it does is: it converts offs into a nand_pos representation. that's it. that's the whole thing. it takes your raw offset and turns it into the pretty structured position form 🎀

lowkey iconic that something so simple gets its own manpage, but we respect it 👑

---

⭐ RETURN ⭐

it returns the offset within the NAND page pointed by pos 💅

so, like, not the same offset you gave it — a different offset, the one that lands inside that specific page. read the return value, bestie, don't just assume 🙈
