gpiod_is_active_low(9)

💅 gpiod_is_active_low(9)

okay so bestie, we're in the Kernel API Manual and the page is gpiod_is_active_low(9) — title and manual name folded in, we're being efficient. This is the tiny vibe check for whether a GPIO is active-low or not. No cap, it's a whole function. ✨

---

🌸 NAME 🌸

gpiod_is_active_low — test whether a GPIO is active-low or not

---

✨ SYNOPSIS ✨

int gpiod_is_active_low (const struct gpio_desc *desc );

---

🎀 ARGUMENTS 🎀

• desc — the gpio descriptor to test

---

🦋 RETURN 🦋

1 if the GPIO is active-low, 0 otherwise. It's giving binary realness. 💅
