gluebi_get_device(9)

💅 gluebi_get_device(9) — the Kernel API Manual, bestie edition

Okay so real talk, this is gluebi_get_device(9) from the Kernel API Manual, and it's lowkey one of those tiny functions that just works and never gets credit. Let's get into it ✨

---

🌸 NAME 🌸

gluebi_get_device — get MTD device reference.

Yes bestie, that's the whole job. It gets you a reference. Iconic, minimal, no notes. 🫶

---

✨ SYNOPSIS ✨

int gluebi_get_device (struct mtd_info *mtd );

That's it. One function, one argument, int coming back at you. Very demure, very mindful. 🎀

---

🦋 ARGUMENTS 🦋

• mtd — the MTD device description object. This is the main character of the whole story, the MTD device description object itself, so like… treat it with respect fr fr. 👑

---

💖 DESCRIPTION 💖

So here's the vibe: this function gets called every time the MTD device is being opened, and it implements the MTD get_device operation. It's the little greeter at the door of your MTD device, holding the clipboard, checking you in. 💅

What does it return? Okay so:

• Returns zero in case of success — slay, you're in. ✅
• Returns a negative error code in case of failure — not the vibe, something went wrong, check the code. 😭

No cap, that's the entire contract. Success = 0, failure = negative error code. Don't overthink it. 🌈

Ngl, gluebi_get_device and gluebi_put_device are literally a matched set — you grab the reference, you give it back. Don't leave it hanging. 🙈
