scan_all(9)

✨ scan_all(9) ✨

okay so real talk, this one is from the Kernel API Manual and it's literally the function that scans your whole MTD device. no cap. 🎀

💅 NAME

scan_all — scan entire MTD device.

🌸 SYNOPSIS

int scan_all (struct ubi_device *ubi , struct ubi_attach_info *ai , int start );

🦋 ARGUMENTS

• ubi — the UBI device description object, aka the whole vibe of the device you're dealing with 🫶
• ai — the attach info object, this is where all the tea gets stored
• start — start scanning at this PEB. yes bestie, this one, right here, that's the starting point ⭐

🔥 DESCRIPTION

so this function does a full scanning of an MTD device and hands you back complete information about it in the form of a "struct ubi_attach_info" object. like, the entire picture, no crumbs left behind 💖

and if things go sideways? in case of failure, an error code is returned. that's it, that's the deal 😭

ngl, "full scanning" means full — it's not doing a little peek, it's the whole device. main character energy fr fr 👑
