ubi_attach(9)

💅 ubi_attach(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in ubi_attach(9) territory and you just need someone to tell you what's going on. that's me. i got you. this one lives in the Kernel API Manual and it's literally about attaching an MTD device, no cap ✨

🎀 NAME 🎀

ubi_attach — attach an MTD device. that's it, that's the whole vibe. it glues your MTD device onto the UBI stack and honestly? iconic. 🦋

---

✨ SYNOPSIS ✨

int ubi_attach (struct ubi_device *ubi , int force_scan );

like, copy it exactly, don't come for me about the spacing, that's how it's written. 💅

---

🌸 ARGUMENTS 🌸

• ubi — the UBI device descriptor. this is your main character right here, the struct that's about to get a whole MTD device attached to it. 👑
• force_scan — if you set this to non-zero, you're doing it the scan way. literally set it to anything non-zero and boom, attach by scanning. zero = not that. 🫶

---

💖 DESCRIPTION 💖

okay so the tea: this function returns zero in case of success, and a negative error code in case of failure. so if you get 0 back you may celebrate, and if you get something negative... that's your sign, bestie, something went wrong 😭

no in-between. no "kinda worked". zero or negative. periodt. 💀
