🌸 gpiochip_fw...ection_input(9) 🌸

okay so bestie, welcome to the Kernel API Manual — this one's all about gpiochip_fwd_gpio_direction_input, and ngl it's a little niche but it's giving "quietly essential" 💅

---

✨ NAME ✨

gpiochip_fwd_gpio_direction_input — set a GPIO forwarder line direction to input 🎀

Like, you're telling one specific line on the forwarder "hey babe, you're an input now" and it just… listens. obsessed.

---

🦋 SYNOPSIS 🦋

int gpiochip_fwd_gpio_direction_input (struct gpiochip_fwd *fwd ,
unsigned int offset );

the way that signature just sits there being all tidy 😭 two args, one int out the front, periodt.

---

💖 ARGUMENTS 💖

• fwd — the GPIO forwarder 🫶 like, the whole forwarder situation you're working with.
• offset — the offset of the line ✨ aka which line we're pointing at. gotta be specific, bestie.

---

⭐ RETURN ⭐

• 0 on success 🎉 slay, it worked
• negative errno on failure 💀 not slay, something went sideways — check that errno, iykyk

okay that's the whole page bestie, ily, go set some directions to input 🌸
