✨ wdt_start(9) ✨

okay so bestie, welcome to the wdt_start(9) page from the Kernel API Manual — yes it's a real kernel thing and yes it's gonna be cute. sit down, grab a strawberry 🍓, this one's short and sweet fr fr.

💖 NAME 💖

wdt_start —

so the original literally leaves the description blank here 😭 no cap, there's nothing after the dash. iconic of it tbh. the actual tea is down in DESCRIPTION, keep scrolling bestie 💅

---

🌸 SYNOPSIS 🌸

int wdt_start (void );

it returns an int, it takes void, that's the whole vibe. main character energy honestly — no parameters, no drama. 🎀

---

🦋 ARGUMENTS 🦋

• void — bestie there are no arguments. zero. none. it takes nothing and it wants nothing. a true minimalist king 👑

---

⭐ DESCRIPTION ⭐

it starts the watchdog driver. that's it, that's the whole thing 🫶

like — Start the watchdog driver. — did you catch that? the watchdog driver? started. by this function. it's giving "the name says it all" and honestly? slay. 💅

(and yeah if you're wondering what the watchdog actually does once it's started, that's a different page's problem, not ours — we just start it here ✨)

---
