gpiod_get_raw_value(9)

📦 version 7.3.1, in nixpkgs unstable

Bestie, welcome to the Kernel API Manual page for gpiod_get_raw_value(9) 💅✨. This is your group-chat cheat sheet for pulling a gpio's raw value, no cap. Let's get into it 🫶

✨ NAME ✨

gpiod_get_raw_value — return a gpio's raw value. Literally what it says on the label, bestie 🌸

🎀 SYNOPSIS 🎀

int gpiod_get_raw_value (const struct gpio_desc *desc );

🦋 ARGUMENTS 🦋

  • desc — the gpio whose value will be returned. That's the one we're checking, bestie 👀

💖 RETURN 💖

The GPIO's raw value, i.e. the value of the physical line disregarding its ACTIVE_LOW status, or negative errno on failure. So you get the physical-line truth, not the active-low-flipped version — and if it fails, a negative errno is the vibe 💀

🔥 DESCRIPTION 🔥

This function can be called from contexts where we cannot sleep, and will complain if the GPIO chip functions potentially sleep. So yes: no-sleep contexts are welcome, but if the GPIO chip functions potentially sleep, it's gonna complain 😭

🌈 SEE ALSO 🌈

Kernel file: ./drivers/gpio/gpiolib.c — and the whole function family is below, bestie. Every single reference, no skips 🫶

Okay that's the whole page, bestie 🫶 Stay raw, stay iconic, and don't forget the ACTIVE_LOW lore 💅✨ This one's from source/version ./drivers/gpio, dated October 2026, for gpiod_get_raw_value(9) — periodt 🎀
