ionic_queue_next(9)

💅 ionic_queue_next — a Kernel API manual, bestie edition ✨

okay so real talk, this is the ionic_queue_next(9) page from the Kernel API Manual, and it's literally the shortest glow-up in the kernel — but it still ate. Let's get into it 🎀

---

✨ NAME ✨

ionic_queue_next — compute the next index 🦋

like, that's it. that's the whole job. and she does it flawlessly, no cap.

---

🌸 SYNOPSIS 🌸

u16 ionic_queue_next (struct ionic_queue *q , u16 idx );

so you hand her a queue pointer and an index, and she gives you back a u16. tiny function, big main character energy 👑

---

💖 ARGUMENTS 💖

• q — the queue structure, aka the struct ionic_queue in question. she needs to know which queue we're talking about, obviously 🫶
• idx — the index. the starting point. the "where we at" of it all 📍

---

⭐ RETURN ⭐

the next index after idx, as a u16. that's the whole vibe check and she passed 💀✨
