device_create_file(9)

💖 device_create_file — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual page for device_create_file and honestly? it's a little one but it's iconic 🎀 this is the whole thing, no cap.

---

🦋 NAME 🦋

device_create_file — create sysfs attribute file for device. periodt. that's literally the whole gig 💅

---

⭐ SYNOPSIS ⭐

int device_create_file (struct device *dev , const struct
device_attribute *attr );

like, yes, it returns an int, and yes, the line wrapping in the original is exactly like that. iykyk 🙈

---

🌸 ARGUMENTS 🌸

okay so there are two (2) of them and here's the tea:

• dev — device. that's the device, bestie. the one getting the file. main character energy 👑
• attr — device attribute descriptor. this is the descriptor describing the attribute. it's giving "the blueprint" ✨

ngl the original is not big on elaboration here, and i refuse to invent lore. two args, two one-line descriptions, we move 💀

okay so this list is LONG and i'm obsessed, it's like the group chat of every function that lives near this one in the kernel. buckle up 🍓

also the page points at the kernel file ./drivers/base/core.c — that's where the source lives, go look if you're nosy 💜

and that's the page!! short and sweet, exactly like the original, no extra crumbs invented 🧚 the whole thing comes from the kernel tree at ./drivers/base, and the date on it is October 2026 — so if you're reading this from the future, hiii, hope your sysfs is slaying 🔥✨💖
