wx_check_for_ack_pf(9)

📦 version 7.3.1, in nixpkgs unstable

💅 wx_check_for_ack_pf(9) — like, the Kernel API Manual bestie ✨

okay so real talk, this page lives in the Kernel API Manual section 9, and it's all about wx_check_for_ack_pf. yes it's a mouthful, no you're not gonna say it out loud at a party 🎀

🌸 NAME 🌸

wx_check_for_ack_pf — checks to see if the VF has acked 🫶

like that's literally its whole job. it checks. for an ack. from the VF. iconic behavior honestly.

✨ SYNOPSIS ✨

int wx_check_for_ack_pf (struct wx *wx , u16 vf );

that's the whole vibe check right there — returns an int, takes a struct wx * and a u16. she's compact, she's efficient, she's giving main character energy 👑

🦋 ARGUMENTS 🦋

  • wx — pointer to the HW structure. your hardware bestie, the one holding all the context 💖
  • vf — the VF index. which VF are we even talking about? this number. this is the number 🔥

🌈 RETURN 🌈

you get 0 if the VF has set the status bit — slay, it acked, we love to see it ✅

or else you get -EBUSY — not me getting handed a -EBUSY, that's the "she's busy, try again later" of error codes 😭

ngl, -EBUSY here means the ack status bit was not set. it's not a "the world is ending" error, it's a "not yet bestie" error. still, check your return values fr fr.
