get_mtd_device_nm(9)

✨ NAME ✨

get_mtd_device_nm — bestie, this is the one that hands you a fully validated handle for an MTD device, and it finds that device by name 💅

(lowkey this is from the Kernel API Manual, in case the <pink>get_mtd_device_nm(9)</pink> header vibe didn't already tip you off 🎀)

---

🌸 SYNOPSIS 🌸

struct mtd_info * get_mtd_device_nm (const char *name );

---

🦋 ARGUMENTS 🦋

• name — the MTD device name you wanna open, fr fr. That's the whole argument, she's a simple girl 🫶

---

💖 DESCRIPTION 💖

okay so picture this: you call this function, and if everything slays, it returns the MTD device description structure for you 👑 like, the actual thing you wanted.

but if it doesn't work out? it returns an error code instead 😭 no in-between, no "maybe", it's giving very binary main character energy.

so basically: success = struct, failure = error code. periodt ✨
