💖 wdrtas_set_interval(9) 💖

okay so real quick — this page lives in the Kernel API Manual and it's all about one tiny little function that pokes the watchdog timer. stay with me bestie, it's short and it slays. 🎀

✨ NAME ✨

wdrtas_set_interval — sets the watchdog interval. that's it. that's the whole gig. 💅

---

🌸 SYNOPSIS 🌸

int wdrtas_set_interval (int interval );

---

🦋 ARGUMENTS 🦋

• interval — the new interval, bestie. the fresh one. the one we're setting. no cap.

---

🔥 DESCRIPTION 🔥

okay so here's the vibe check: wdrtas_set_interval sets the watchdog keepalive interval by calling the RTAS function set-indicator (surveillance). the way it just… delegates. iconic. 👑

and the unit of interval? seconds. literally seconds. don't come at it with milliseconds, it will not understand you. ⏱️

what does it return, you ask? 🫶

• it returns 0 on success (we love a zero, periodt)
• it returns <0 on failures (😭 not the negative numbers)
