xgpio_dir_in(9)

💖 NAME 💖

xgpio_dir_in — Set the direction of the specified GPIO signal as input.

okay so welcome to the xgpio_dir_in(9) page from the Kernel API Manual, bestie 🫶 this one is short and sweet: it’s all about setting the direction of the specified GPIO signal as input ✨

✨ SYNOPSIS ✨

the whole signature, no cap:

int xgpio_dir_in (struct gpio_chip *gc , unsigned int gpio );

🎀 ARGUMENTS 🎀

• gc — Pointer to the gpio_chip device structure. that’s the device struct pointer, periodt 💅
• gpio — GPIO signal number. yep, the signal’s number bestie 🔢

🌈 RETURN 🌈

• 0 — if direction of GPIO signals is set as input; otherwise it returns a negative error value. so 0 is the slay outcome, negative means something went sideways 😭
