🌸 pc87413_open(9) 🌸

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're not skipping it, it's part of the lore 💅. This one's a tiny little page about a tiny little function, and honestly? It's giving "underrated side character with main character energy."

✨ NAME ✨

pc87413_open —

and that's it. That's the whole description. Not me staring at a blank line like 😭. The manpage literally trailed off with a dash and left us hanging. No cap, that's what's there.

🎀 SYNOPSIS 🎀

int pc87413_open (struct inode *inode , struct file *file );

Look at her. Two args, both pointers, returns an int. Classic. Iconic. Fr fr.

---

🦋 ARGUMENTS 🦋

• inode — the inode of device 💖 yeah, the actual inode, the filesystem's little ID card for the thing. That's what gets handed over.
• file — the file handle to device 🌸 like, the handle you get to poke at the device with.

That's the whole cast. Two arguments, no notes. 🫶

👑 SEE ALSO 👑

okay so if you liked this one (and you did, don't lie), the whole friend group lives in the kernel source file ./drivers/watchdog/pc87413_wdt.c, and the squad is:

• pc87413_release(9)
• pc87413_status(9)
• pc87413_write(9)
• pc87413_ioctl(9)
• pc87413_notify_sys(9)
• pc87413_init(9)
• pc87413_exit(9)

go read them, they're literally right there, iykyk 💜

real talk though — this page tells you the signature and the args and nothing else about behaviour, so don't go assuming stuff. Read the source. 🧚

and that's the whole vibe check, bestie! 🌈 this little gem comes to you from the ./drivers/watchdog corner of the kernel tree, dated October 2026, and it's filed under pc87413_open(9) — mwah, slay, periodt 💅💖
