atcwdt_get_clock_period(9)

💅 atcwdt_get_clock_period(9) 💅

ok so bestie, welcome to the Kernel API Manual ✨ — today's main character is atcwdt_get_clock_period(9), and honestly? she's doing the math so you don't have to 🧮💖

---

🌸 NAME 🌸

atcwdt_get_clock_period — calculates the closest clock period based on a given tick count 🎯 like, that's literally her whole job

---

✨ SYNOPSIS ✨

long long atcwdt_get_clock_period (long long tick , enum timer_type
timer_type , unsigned char *index );

three params in, one long long out — no cap, she keeps it simple 🫶

---

🎀 ARGUMENTS 🎀

• tick — the target tick count you're trying to match 🌟 this is the vibe you're aiming for
• timer_type — the type of timer, and it can be TMR_RST, TMR_INT_16, or TMR_INT_32 👑 (yes, exactly those three, don't get creative)
• index — a pointer where the index of the selected parameter gets stored 📍 so she'll write back into it, keep that in mind

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: this function calculates the closest clock period to the given tick count by iterating through the timer parameters and picking the one that minimizes the difference between your target tick count and the calculated clock period. the way that she just... goes through them all and finds the bestie that fits closest, no drama 💅

then she figures out the index of that closest parameter (remember that pointer? yeah, that's where it goes 🎯) and returns the difference between the target tick count and the selected clock period. so the return value is basically a report card of how close she got 📊✨

---

🔥 RETURN 🔥

the difference between the target tick count and the selected clock period 💀 that's it, that's the whole return. a number that tells you how far off the chosen period is from what you asked for ✨
