gpiod_direction_output_raw(9)

💅 gpiod_direction_output_raw(9) 💅

okay bestie, welcome to the Kernel API Manual entry for gpiod_direction_output_raw — yes, this is the one that sets a GPIO’s direction to output. Main character energy for a tiny pin. 🦋

---

🌸 NAME 🌸

gpiod_direction_output_raw — set the GPIO direction to output.

---

✨ SYNOPSIS ✨

int gpiod_direction_output_raw (struct gpio_desc *desc , int value );

---

🎀 ARGUMENTS 🎀

• desc — the GPIO you’re setting to output. 💅
• value — the initial output value of the GPIO. 🍓

---

💅 DESCRIPTION 💅

okay so: this sets the direction of the passed GPIO to output. That’s the kind of setup where gpiod_set_value can be called safely on it.

Important detail, no skipping: the initial value of the output must be specified as a raw value on the physical line — without regard for the ACTIVE_LOW status. Like, raw raw. 💀

---

🔥 RETURN 🔥

0 on success, or a negative errno on failure. Slay when it’s zero, sad little bug when it’s negative. 😭
