okay so welcome to the Kernel API Manual bestie, this is ap_qact(9) and it's giving "short but iconic" 🎀

🌸 NAME 🌸

ap_qact — Query AP compatibility type. that's it, that's the whole vibe 💅

---

✨ SYNOPSIS ✨

struct ap_queue_status ap_qact (ap_qid_t qid , int ifbit , union
ap_qact_ap_info *apinfo );

literally the whole signature, copy it exactly, no cap 🫶

---

🦋 ARGUMENTS 🦋

• qid — The AP queue number. that's your queue, your main character identifier 👑
• ifbit — -- undescribed -- 😭 and no, bestie, I'm not making that up, the page really does say -- undescribed --. we simply do not know. it remains a mystery. 💀
• apinfo — On input, the info about the AP queue. On output, the alternate AP queue info provided by the qact function in GR2 is stored in. so it's a glow-up container: goes in as one thing, comes out holding the alternate AP queue info from qact in GR2 ✨

---

💖 DESCRIPTION 💖

Returns AP queue status. 👀

Check the response_code field for failures — fr fr, do not skip this, that's your vibe check on whether things actually worked 🔥
