💅 hfi1_seq_incr_wrap(9) — from the Kernel API Manual, bestie ✨

Okay so bestie, we're diving into the hfi1_seq_incr_wrap(9) page from the Kernel API Manual and honestly? It's a little cutie. Tiny function, big job. Let's get into it 🫶

🌸 NAME 🌸

hfi1_seq_incr_wrap — the wrapping increment for a sequence, no cap

Like, it bumps your sequence number up by one, but with the wrap-around energy. Main character behavior tbh 👑

---

✨ SYNOPSIS ✨

u8 hfi1_seq_incr_wrap (u8 seq );

That's it. That's the whole vibe. One argument, one return, zero drama 💖

---

🎀 ARGUMENTS 🎀

• seq — the current sequence number, aka the lil guy you're about to increment. Hand it over and it gets the glow-up ✨

---

🦋 RETURN 🦋

You get back the incremented seq. That's the whole plot twist — it's just your sequence number, but incremented. Periodt 💅
