hl_eq_inc_ptr(9)

💅 hl_eq_inc_ptr(9) — the Kernel API Manual moment

okay so bestie, welcome to the hl_eq_inc_ptr page from the Kernel API Manual ✨ this one is short and sweet and honestly kind of iconic for it 🎀

---

🌸 NAME 🌸

hl_eq_inc_ptr — increment ci of eq 💫

like, yes, that's literally the whole name section. she's efficient.

---

✨ SYNOPSIS ✨

u32 hl_eq_inc_ptr (u32 ptr );

(no cap, keep that stray space before the ) — it's part of the original vibe 🫶)

---

🦋 ARGUMENTS 🦋

• ptr — the current ci value of the event queue 👑 this is the number you're about to scoot forward by one, bestie.

---

💖 DESCRIPTION 💖

So here's the whole tea: it increments ptr by 1. That's it. That's the function. 💅

But wait — plot twist 🎬 if that incremented value reaches the number of event queue entries, it gets set to 0 instead. So it's giving circular buffer main character energy 🌈 wrap-around slay, periodt.

lowkey this is the "when you hit the end of the list, go back to the top" friend in the group chat. she keeps the queue from falling off the edge 🧚
