💅 pc87413_exit(9) — Kernel API Manual, bestie edition 💅

okay so this is the Kernel API Manual page for pc87413_exit(9), and it's giving "module goodbye era" in the best way 🫶✨

🌸 NAME 🌸

pc87413_exit — the module's "destructor" 🎀

✨ SYNOPSIS ✨

void pc87413_exit (void );

🎀 ARGUMENTS 🎀

• void — no arguments, literally nothing to pass in, not a single one, periodt 🫶

🔥 DESCRIPTION 🔥

okay so this is the unload-the-watchdog moment. You cannot do this with any file handles open — like, none, bestie 😭 close them first.

If your watchdog is set to continue ticking on close and you unload it, well… it keeps ticking. We won't get the interrupt, but the board will not touch PC memory, so all is fine. You just have to load a new module in 60 seconds or reboot. No cap 💅

⚠️ lowkey important: 60 seconds is the countdown, and reboot is the escape hatch. Keep that in mind, bestie 🫶
