💖 v4l2_timeval_to_ns(9) 💖

okay bestie, so this one is a kernel API page — it lives in the Kernel API Manual, and it's genuinely the shortest little icon you'll ever meet. It's giving "one job, does it flawlessly." 🎀

---

✨ NAME ✨

v4l2_timeval_to_ns — literally just convert a timeval into nanoseconds. That's the whole personality. 🦋

---

🌸 SYNOPSIS 🌸

__u64 v4l2_timeval_to_ns (const struct timeval *tv );

---

🎀 ARGUMENTS 🎀

• tv — pointer to the timeval variable you want converted. Yep, a pointer. You're handing it the address of your timeval and it does the glow-up for you. 💅

---

💜 DESCRIPTION 💜

So what does it actually do? It returns the scalar nanosecond representation of the timeval you passed in. That's it. That's the function. You give it a timeval, it gives you back a __u64 counting nanoseconds. No cap, it's that clean. ✨

okay that's the whole page, and honestly? Iconic. This doc ships from the directory ./include/uapi/linux, dated October 2026 — so yeah, future vibes only. 🧚 Go convert some timevals, bestie, you got this 💖🫶🌈
