💖 led_sysfs_is_disabled(9) 💖

okay so this is a page straight out of the Kernel API Manual — it's led_sysfs_is_disabled(9), and bestie, it's literally a one-job function and it does that job flawlessly. no notes. 🎀

---

✨ NAME ✨

led_sysfs_is_disabled — check if the LED sysfs interface is disabled 💅

like, that's it. that's the whole vibe check. it peeks at your LED and tells you whether its sysfs interface has been switched off.

---

🌸 SYNOPSIS 🌸

bool led_sysfs_is_disabled (struct led_classdev *led_cdev );

one function, one pointer in, one bool out. immaculate. 🔥

---

🦋 ARGUMENTS 🦋

• led_cdev — the LED you wanna query 👀 literally just hand it the struct led_classdev * of the light you're curious about.

---

⭐ RETURN ⭐

it returns true if the led_cdev's sysfs interface is disabled. that's the whole answer. no cap. if it's disabled you get true, periodt. 💯

ngl, the manpage only spells out the true case — so don't go making up extra promises about what it returns otherwise, iykyk 🫶
