gpiochip_fwd_desc_add(9)

✨ gpiochip_fwd_desc_add — the "add a GPIO desc to the forwarder" era ✨

okay bestie, welcome to the Kernel API Manual page for gpiochip_fwd_desc_add(9) 💅 this lil function is literally here to Add a GPIO desc in the forwarder — that's the whole vibe, no cap 🦋

---

🌸 NAME 🌸

gpiochip_fwd_desc_add — Add a GPIO desc in the forwarder 👑

---

🎀 SYNOPSIS 🎀

int gpiochip_fwd_desc_add (struct gpiochip_fwd *fwd , struct gpio_desc
*desc , unsigned int offset );

like, that's the whole signature, copy it exactly or the compiler WILL humble you 😭

---

🧚 ARGUMENTS 🧚

• fwd — the GPIO forwarder itself ✨ this is the main character, the thing everything's getting added into.
• desc — the GPIO descriptor you're registering 🫶 the lil guy you're bringing to the party.
• offset — where in the forwarder this GPIO sits 🌈 the offset for the GPIO in the forwarder, iykyk.

---

⭐ RETURN ⭐

0 on success 🎉 or a negative errno on failure 💀 that's it, that's the whole mood.

ngl bestie, always check the return value. a negative errno is not a vibe.
