wdtpci_ioctl(9)

📦 version 7.3.1, in nixpkgs unstable

💖 wdtpci_ioctl(9) — a Kernel API Manual moment 💖

okay so bestie, grab your iced coffee because we're diving into wdtpci_ioctl — yes it's a real manual page from the Kernel API Manual, section 9, and no I will not be normal about it 🫶

✨ NAME ✨

wdtpci_ioctl — literally the function, that's the whole name, the original page gave us no description here and honestly? iconic of it to leave us hanging 💅

🌸 SYNOPSIS 🌸

long wdtpci_ioctl (struct file *file , unsigned int cmd , unsigned long arg );

that's the whole vibe. three args, one long coming back at you. periodt. ✨

🎀 ARGUMENTS 🎀

  • file — the file handle to the device, like your little pass into the club 🪪
  • cmd — the watchdog command, aka what you're actually asking the dog to do 🐕
  • arg — an argument pointer, it's giving "here's the rest of the info, go off" 🫶

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — the watchdog API defines a common set of functions for all watchdogs, and it tailors them according to their available features. so like, whatever your watchdog can actually do, that's what you get. 🐶✨

and then the real talk: we only actually usefully support two things — querying capabilities and current status. that's it. that's the whole menu. no cap, don't go looking for more, because the page said so and the page does not lie 😭💀

lowkey important: this isn't "here's everything a watchdog ioctl could theoretically do," it's "here's what genuinely works." manage your expectations accordingly bestie 💖

🌈 SEE ALSO 🌈

the kernel file in question is ./drivers/watchdog/wdt_pci.c — go read it, it's giving main character energy 👑

and then the whole friend group of related calls, all in section 9, all absolutely invited to the group chat:

like, thirteen whole besties. collect them all 🍓🧚

and that's the page!! sign-off time: this little love letter lives in ./drivers/watchdog and it's dated October 2026 — so yeah, future-dated and thriving, we love a timestamp that ate 🔥👑 bye bestie, go ping your watchdog 💜✨
