attribute_c...class_device(9)

📦 version 7.3.1, in nixpkgs unstable

💅 attribute_c...class_device(9) — from the Kernel API Manual, bestie

okay so this is a man page from the Kernel API Manual and honestly? it's a short one, so let's get into it 🎀

✨ NAME ✨

attribute_container_find_class_device — the little function whose whole personality is finding the corresponding class_device 🕵️‍♀️

🌸 SYNOPSIS 🌸

struct device * attribute_container_find_class_device (struct attribute_container *cont , struct device *dev );

like, that's the whole signature. take it in. struct device * in, struct device * out — it's giving symmetry 💫

🦋 ARGUMENTS 🦋

  • cont — the container. yeah. that one. the container container 🫙
  • dev — the generic device. the plain one. the no-frills one. main character but make it generic ✨

💖 DESCRIPTION 💖

so what does it do? it looks up the device in the container's list of class devices, and then it returns the corresponding class_device. that's it. that's the whole bit. short, sweet, slays, done 💅

ngl it's a lookup. it finds the thing in the list and hands it back to you. iconic behaviour, zero notes 🔥

👑 SEE ALSO 👑

the kernel file it lives in, for the curious girlies who like to read source:

Kernel file ./drivers/base/attribute_container.c

and the whole friend group, in the order the original gives them:

💀 quick reminder bestie: every one of those is a real sibling function — go read them, don't just guess at what they do, okay? iykyk 🙈

and that's the page!! 🧚 sign-off time: this one comes out of ./drivers/base, and the version date on it is October 2026. mwah, go forth and find your class_device 💜🎀🦋
