ata_link_offline(9)

📦 version 7.3.1, in nixpkgs unstable

okay so you're reading ata_link_offline(9) from the Kernel API Manual and honestly? iconic choice. let's get into it 🫶

✨ NAME ✨

ata_link_offline — test whether the given link is offline

like literally just a vibe check for your link. is it offline or not. that's the whole job 💀

🌸 SYNOPSIS 🌸

bool ata_link_offline (struct ata_link *link );

returns a bool, takes a struct ata_link * named link. short and sweet, no notes 👑

🎀 ARGUMENTS 🎀

  • link — the ATA link to test. this is the thing you're asking about, bestie. hand it over and the function will tell you its whole situation 🔍

🦋 DESCRIPTION 🦋

so the function tests whether link is offline. that's it, that's the plot ✨

it's identical to ata_phys_link_offline when there's no slave link. no slave? same thing, different name, they're twinning fr fr 💅

but when there is a slave link, there are RULES, okay? this function should only be called on the master link — like, main character energy only, the slave link does not get to be the one you call it on 🙈 and when you do call it on the master, it returns true if both the M/S links are offline. both. not one. both. periodt 💯

LOCKING: None. — no locking, no stress, no hoops to jump through. it's giving low maintenance 🧚

⭐ RETURN ⭐

returns true if the port offline status is available and offline. two boxes to tick, bestie ✅✅
