okay so real talk, this one is short and sweet and it's from the Kernel API Manual, and honestly? we love a low-effort icon ✨

🌸 NAME 🌸

ap_airq_ptr — grab the address of the adapter interrupt indicator, no cap 🫶

---

✨ SYNOPSIS ✨

void * ap_airq_ptr (void );

---

🦋 ARGUMENTS 🦋

• void — literally no arguments. nothing. nada. she takes zero input and she's thriving 💅

---

💖 DESCRIPTION 💖

so what she does is she returns the address of the local-summary-indicator of the adapter interrupt handler for AP ⭐

and if adapter interrupts aren't available? she hits you with NULL. that's it, that's the whole vibe 😭 she's not gonna fake it for you, bestie — if the thing isn't there, she tells you it isn't there 🙈

lowkey the most emotionally honest function in the whole bus. respect 👑
