RETRIEVE NOTIFICATION(9)

🎀 retrieve notification(9) 🎀

straight from the Kernel API Manual, bestie — this is the whole vibe for retrieve notification. 💅

okay so first things first: the IOCTL output argument is 1 if an event was pending and 0 otherwise. literally that's the output tea. 🫶

The ioctl has to be called in order to acknowledge pending event. no cap — that's the acknowledgment step, you can't just ghost it. 💅

Return: -EOPNOTSUPP if the devices doesn't support the feature 😭
