register_atm_ioctl(9)

hey bestie 💖 welcome to the register_atm_ioctl(9) page from the Kernel API Manual — it’s giving “kernel plumbing but make it cute,” and we’re gonna get through it together, fr fr ✨

✨ NAME ✨

register_atm_ioctl — register handler for ioctl operations 💅

🎀 SYNOPSIS 🎀

okay so the function signature is literally this:

void register_atm_ioctl (struct atm_ioctl *ioctl );

🌸 ARGUMENTS 🌸

• ioctl — the ioctl handler you want to register 🫶 that’s the one and only argument, bestie.

🦋 DESCRIPTION 🦋

okay so here’s the tea: special handlers of ioctl’s — the non-device ones — should register right here. Like, this is their spot. ✨

If you’re a normal device, tho? This is not your lane. You should set .ioctl in your atmdev_ops instead. Periodt. 💅
