gpiod_toggle_active_low(9)

💅 gpiod_toggle_active_low(9) — a lil' page from the Kernel API Manual

okay so bestie, this one is short and sweet and honestly? iconic. we're in the Kernel API Manual, section 9, and the whole vibe is: flip a GPIO's polarity. that's it. that's the function. 🦋

---

✨ NAME ✨

gpiod_toggle_active_low — toggle whether a GPIO is active-low or not

like, literally flip the bit on whether "active" means high or low. no cap. 💅

---

🌸 SYNOPSIS 🌸

void gpiod_toggle_active_low (struct gpio_desc *desc );

note the void — this thing hands you back nothing. it just does the thing and dips. main character energy fr fr. 👑

---

🎀 ARGUMENTS 🎀

• desc — the gpio descriptor to change 🌈 this is the lil' handle for the GPIO line you wanna flip the polarity on. give it the descriptor, it toggles away. simple as that, periodt.

and that's the page, bestie!! 🫶 sign-off time: this lil' gem comes out of ./drivers/gpio, dated October 2026, and it's titled gpiod_toggle_active_low(9). slay, go toggle something. 💜✨
