DEVICE_INT_ATTR(9)

💅 DEVICE_INT_ATTR 💅

okay so bestie, this one is from the Kernel API Manual — section 9, the driver/kernel zone. it's a macro. it's tiny. but she's important, so let's give her the main character energy she deserves. 🫶

---

✨ NAME ✨

DEVICE_INT_ATTR — literally the macro that defines a device attribute backed by an int. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

DEVICE_INT_ATTR (_name , _mode , _var );

(yes the spacing is exactly like that, don't @ me, that's how the page prints it 💀)

---

🦋 ARGUMENTS 🦋

• _name — the attribute name, aka what this thing is called 💖
• _mode — the file mode, yep, the permissions situation 🌈
• _var — the identifier of an int. like, the actual variable. the star of the show ⭐

---

👑 DESCRIPTION 👑

ok so the manpage is being ✨minimalist✨ here, and honestly? iconic of her. it says:

Like DEVICE_ULONG_ATTR, but _var is an int.

that's the whole description. no cap. so if you already know DEVICE_ULONG_ATTR, you know this one — same energy, except the backing variable is an int instead of an unsigned long. and if you don't know DEVICE_ULONG_ATTR... bestie, go read that one, iykyk 😭

this list is LONG and she did NOT come to play. every single one, in order, no skipping 🔥

and that's the page, bestie!! 🍓 cute little sign-off time: this beauty lives over in ./include/linux, and the page is dated October 2026. mwah. go define some int-backed device attributes. slay. 💜
