💖 ath5k_check_timer_win(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ you're about to meet ath5k_check_timer_win, and honestly? she's doing a lot of quiet heavy lifting. let's get into it 🫶

---

🌸 NAME 🌸

ath5k_check_timer_win — check if timer B is timer A + window 💅

---

✨ SYNOPSIS ✨

bool ath5k_check_timer_win (int a , int b , int window , int intval );

---

🎀 ARGUMENTS 🎀

• a — timer a (before b) ⏪
• b — timer b (after a) ⏩
• window — the difference between a and b 📏
• intval — timers are increased by this interval 🔁

---

🦋 DESCRIPTION 🦋

so this helper function checks if timer B is timer A + window, and it's lowkey iconic because it also covers the messy cases where timer A or B might have already been updated or wrapped around — and yeah, timers are 16 bit, so wrapping is very much a thing that happens 🙈

returns true if O.K. ✅ no cap, that's the whole vibe check.
