ktime_get_ts64(9)

✨ ktime_get_ts64 ✨

_{the manual page, but make it make sense — from the Linux Kernel API Manual, bestie 🫶}

---

🌸 NAME 🌸

ktime_get_ts64 — get the monotonic clock in timespec64 format

---

🎀 SYNOPSIS 🎀

void ktime_get_ts64 (struct timespec64 *ts );

---

🦋 ARGUMENTS 🦋

• ts — bestie, this is a pointer to a timespec variable. it's where the result goes. that's it. that's the whole vibe. 💅

---

💖 DESCRIPTION 💖

Okay so picture this: the function calculates the monotonic clock from the realtime clock and the wall_to_monotonic offset ✨ and then stores the result in normalized timespec64 format in the variable that ts is pointing at. like, it does the math, it normalizes it, it drops it in the box. the way that works is honestly iconic. no cap. 👑

quick reminder: ts is a pointer to a timespec64 variable — you're not passing the struct, you're passing the address of it. so, lowkey, make sure it's valid or it's a whole situation 😭
