badblocks_show(9)

hiii bestie 💖 we're looking at badblocks_show(9) from the Kernel API Manual, and it's giving kernel-internals realness. lowkey iconic, ngl. let's go 🌈

✨ NAME ✨

badblocks_show — sysfs access to the bad-blocks list. no cap, that's the whole name-and-purpose situation. slay.

🦋 SYNOPSIS 🦋

the signature is literally this, character for character, don't @ me:

ssize_t badblocks_show (struct badblocks *bb , char *page , int unack );

💅 ARGUMENTS 💅

okay so the arguments are lowkey simple, and each one is doing its little job:

• bb — the badblocks structure that holds all badblock information. it's the main character holding all the receipts, fr fr.
• page — buffer received from sysfs. it's the little delivery container, periodt.
• unack — weather to show unacknowledged badblocks. yes, the original says “weather” — we're keeping that exact spelling, it's part of the lore 💀.

🎀 RETURN 🎀

Length of returned data. that's it, that's the return value — a length. highkey simple, and we love that for us.
