✨ attribute_container_device_trigger ✨

okay so this is a page from the Kernel API Manual, bestie, and we're talking about attribute_container_device_trigger — the little function that goes through and fires off a trigger for every single classdev that matches 🎯

---

🌸 NAME 🌸

attribute_container_device_trigger — literally execute a trigger for each matching classdev, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

void attribute_container_device_trigger (struct device *dev , int
(*fn)(struct attribute_container *, struct device *, struct device *) );

like, it returns void and takes a device plus a function pointer. simple queen behaviour ✨

---

🎀 ARGUMENTS 🎀

• dev — the generic device you're running the trigger for, like the main character of this whole operation 👑
• fn — the function to execute for each classdev. it's a function pointer, so it gets struct attribute_container *, struct device *, and another struct device *. yeah, it eats three args, she's hungry 🍓

---

💖 DESCRIPTION 💖

so here's the tea: this function is for executing a trigger when you need to know both the container and the classdev. both. not one. not the other. both. it's giving "i want it all" energy and honestly? respect 🫶

no cap, that's the entire thing — you call it, it runs your fn across each matching classdev, and you get the container and the classdev handed to you. iconic 🔥
