ksz_start_timer(9)

💖 ksz_start_timer(9) — the kernel API manual, but make it make sense

okay so bestie, we're in the Kernel API Manual today, section 9, and the star of the show is ksz_start_timer — the function that literally just… starts a kernel timer. that's it. that's the whole vibe. but she's iconic for it 💅

---

✨ NAME ✨

ksz_start_timer — start kernel timer 🔥

no cap, that's the whole job description.

---

🫶 SYNOPSIS 🫶

void ksz_start_timer (struct ksz_timer_info *info , int time );

look at her. returns void, takes two things, gets straight to business. main character energy fr fr 👑

---

🎀 ARGUMENTS 🎀

• info — Kernel timer information. this is the struct that knows everything about the timer, like struct ksz_timer_info — it's giving "the timer's whole personality in one pointer" 🦋
• time — The time tick. that's the countdown. literally the number of ticks you're waiting before the timer does its little thing ⏰

---

🌸 DESCRIPTION 🌸

This routine starts the kernel timer after the specified time tick.

yep, that's the tea ☕ — you hand it the timer info, you hand it a tick count, and she fires up the timer to go off after that many ticks. short, sweet, no notes. ate and left no crumbs 💅✨

🦋 SEE ALSO 🦋

bestie. sit down. this list is long and i refuse to skip a single one of them because every single reference is a real one and they all deserve their moment 🌈
