comedi_driver_unregister(9)

💅 comedi_driver_unregister(9) — like, the Kernel API Manual page, bestie 🎀

okay so this is comedi_driver_unregister(9), live from the Kernel API Manual ✨

🌸 NAME 🌸

comedi_driver_unregister — unregister a low-level COMEDI driver 🫶

✨ SYNOPSIS ✨

void comedi_driver_unregister (struct comedi_driver *driver );

🦋 ARGUMENTS 🦋

• driver — the low-level COMEDI driver, like, the actual one you're kicking out 👑 no cap.

💖 DESCRIPTION 💖

So the low-level COMEDI driver gets removed from the list of registered COMEDI drivers. Gone. Not on the list anymore. Periodt. 💀

And it doesn't just ghost the list — it detaches any COMEDI devices attached to the driver, which means the low-level driver's 'detach' handler gets called for those devices before this function returns. So like, the cleanup literally happens before you get control back. No sneaky async vibes. The way that works is honestly iconic ngl 🔥

fr fr: when this returns, the detach handlers have already run. Not later. Before. iykyk 💅
