module_comedi_driver(9)

💖 module_comedi_driver(9) 💖

okay bestie, this is a page from the Kernel API Manual and it's literally about a macro that does your boilerplate for you, no cap 🎀

---

✨ NAME ✨

module_comedi_driver — the helper macro that handles registering a comedi driver for you, slay 💅

---

🦋 SYNOPSIS 🦋

module_comedi_driver (__comedi_driver );

---

🌸 ARGUMENTS 🌸

• __comedi_driver — the comedi_driver struct, that's it, that's the whole argument 🫶

---

🌈 DESCRIPTION 🌈

okay so picture this: you're writing a comedi driver and it genuinely does nothing special in module init/exit. no extra setup, no teardown drama, just vibes. this macro is for exactly that 💖

it's the helper macro for comedi drivers like that, and it eliminates a lot of boilerplate — like, the way it just eats all that repetitive code is iconic, honestly. ✨

⚠️ important bestie: each module may only use this macro once. one and done, no double dipping 🙈

also key: calling it replaces module_init and module_exit. so you don't write those yourself anymore — this macro is the main character now 👑
