pinctrl_gpio_get_config(9)

💖 NAME 💖

okay bestie, this is pinctrl_gpio_get_config(9) from the Kernel API Manual, and it's giving tiny-but-important helper energy. Its whole job? Get the config for a given GPIO pin. slay. 💅

✨ SYNOPSIS ✨

int pinctrl_gpio_get_config (struct gpio_chip *gc , unsigned int offset
, unsigned long *config );

🎀 ARGUMENTS 🎀

• gc — the GPIO chip structure from the GPIO subsystem. that's the main-character struct right there 🫶
• offset — the hardware offset of the GPIO relative to the controller. precise, iconic, no cap 📍
• config — the configuration to query. on success it holds the result. so yes, this pointer comes back with the goods ✨

🌈 RETURN 🌈

0 on success, negative errno otherwise. that's the whole vibe check: zero means we ate, negative means something went sideways 😭
