secs_to_jiffies(9)

🕐 secs_to_jiffies(9) — the Kernel API Manual bestie edition ✨

Okay so picture this: you're in the kernel, you've got a number of seconds in your hand, and everyone around you is speaking jiffies. Rude, honestly. That's where secs_to_jiffies comes in — she's the translator friend, and she's iconic for it. 💅 (Manual section 9, kernel API, iykyk.)

✨ SYNOPSIS ✨

secs_to_jiffies (_secs );

That's it. One argument, zero drama. 🎀

---

🌸 ARGUMENTS 🌸

• _secs — your time, in seconds. Just seconds. That's the whole vibe check. ⏱️

---

💖 DESCRIPTION 💖

So the conversion lowkey could not be simpler: it's a simple multiplication with HZ. That's the entire trick. Multiply by HZ, done, slay. 🔥

Now here's the part that's actually kind of genius: secs_to_jiffies is defined as a macro rather than a static inline function — not to be quirky, but specifically so it can be used in static initializers. Yes bestie, that's the whole reason. Main character design choice fr fr. 👑

---

🦋 RETURN 🦋

The jiffies value. That's what you get back. 🫶

ngl the whole time-conversion family is worth a scroll — but you didn't hear it from me. 🙈

And that's the page! 🎀 This one lives over in ./include/linux and it's dated October 2026 — that's the source and the date, bestie, noted and cherished. Byeee, go convert some seconds. 💖🌈🧚
