🦋 zynq_gpio_get_direction(9) 🦋

okay so bestie, this is the Kernel API Manual entry for zynq_gpio_get_direction(9) — and it’s literally about reading the direction of the specified GPIO pin. main character energy for one tiny function, honestly 💅

---

✨ NAME ✨

zynq_gpio_get_direction — read the direction of the specified GPIO pin. that’s the whole serve, no cap 🎀

---

🌸 SYNOPSIS 🌸

int zynq_gpio_get_direction (struct gpio_chip *chip , unsigned int pin
       );

---

💖 ARGUMENTS 💖

• chip — the gpio_chip instance you’re working on, bestie 🫶
• pin — the gpio pin number within the device, iykyk ⭐

---

🦋 DESCRIPTION 🦋

this function returns the direction of the specified GPIO. that’s it, that’s the vibe check 💫

---

🔥 RETURN 🔥

it’s giving one of these two, periodt:

• GPIO_LINE_DIRECTION_OUT
• GPIO_LINE_DIRECTION_IN
