💖 watchdog_set_pretimeout(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's a little function called watchdog_set_pretimeout and honestly? it's giving "small but important." it does exactly one thing and it does it slayfully: it sets the watchdog timer pretimeout. that's it. that's the whole vibe. ✨

🌸 NAME 🌸

watchdog_set_pretimeout — set the watchdog timer pretimeout, no cap 🐕🦋

⭐ SYNOPSIS ⭐

int watchdog_set_pretimeout (struct watchdog_device *wdd , unsigned int
timeout );

like, it returns an int, takes a struct watchdog_device *wdd and an unsigned int timeout, and that's the whole signature. copy it exactly, i'm not kidding, character for character 💅

🎀 ARGUMENTS 🎀

  • wdd — the watchdog device you're setting the timeout for 🐶 like, the actual device struct, the main character here
  • timeout — the pretimeout to set, measured in seconds ⏱️ so if you want it in minutes you do the math yourself, bestie, this function is not doing it for you

✨ RETURN ✨

0 if it all worked out — successful, slay, we love to see it 💖

anything else? that's an error, and no, the page doesn't promise you which error, just "error otherwise." so check your return values, fr fr 🙈

ok tiny note: this is a 9 manpage, so it's kernel API territory — not your "just type it in a shell" situation. 🧚

and that's the whole page, bestie!! 🌈 source is ./drivers/watchdog, dated October 2026, and the manpage is watchdog_set_pretimeout(9) — go forth and set those pretimeouts responsibly 🫶💜🍓
