gpiochip_fwd_gpio_request(9)

💅 gpiochip_fwd_gpio_request(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a little function from the GPIO forwarder world and it's literally about asking nicely for a line 🎀

---

✨ NAME ✨

gpiochip_fwd_gpio_request — the one where you request a line of the GPIO forwarder 🫶

---

🌸 SYNOPSIS 🌸

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

yes that's the whole thing, she's compact, she's iconic, no cap 💅

---

🦋 ARGUMENTS 🦋

• fwd — the GPIO forwarder itself 💖 your main character struct
• offset — the offset of the line to request, like which line you're claiming. be specific, bestie 🎯

---

⭐ RETURN ⭐

0 on success ✨ or a negative errno on failure 😭 — so like, if it's not 0, something went sideways and that negative number is the receipts.
