modepin_gpio_set_value(9)

✨ modepin_gpio_set_value — like, the manual page (section 9, Kernel API Manual, bestie) ✨

Okay so picture this: you're deep in the kernel, section 9 of the Kernel API Manual, and you need to poke a pin into a new state. That's the whole vibe of modepin_gpio_set_value. Buckle up, it's a short one but it eats. 💅

🌸 NAME 🌸

modepin_gpio_set_value — Modify the state of the pin with specified value 🎀

---

🦋 SYNOPSIS 🦋

int modepin_gpio_set_value (struct gpio_chip *chip , unsigned int pin ,
int state );

---

💖 ARGUMENTS 💖

• chip — the gpio_chip instance you're working on, like, the whole device vibe you're about to touch 🫶
• pin — the gpio pin number within the device, iykyk, it's device-relative
• state — the value used to modify the state of the specified pin. the moment. the main character of this function honestly ✨

---

💜 DESCRIPTION 💜

okay so here's what happens, no cap: this function reads the state of the specified pin of the GPIO device, masks it with the capture state of the GPIO pin, and then updates the pin of the GPIO device. that's literally it. read, mask, update. iconic three-step routine 🔥

---

⭐ RETURN ⭐

None. yeah bestie, that's what it says. None. don't come for me, I'm just the messenger 😭

fr fr the synopsis says int but the RETURN section says None. — that's what the page says, so that's what you get 💀
