ENUM GPIO_V2_LINE_ATTR_ID(9)

✨ ENUM GPIO_V2_LINE_ATTR_ID(9) ✨

okay so bestie, welcome to the manual page for enum gpio_v2_line_attr_id — from the Kernel API Manual, no biggie 💅 this little icon tells you which field of the attribute union is actually in use, like a vibe check for a C union 🫶

---

🌸 NAME 🌸

enum gpio_v2_line_attr_id — literally the values for &struct gpio_v2_line_attribute.id, and they're the ones that say which field of the attribute union is in use. that's the whole job. iconic honestly 👑

---

🎀 SYNOPSIS 🎀

here's the shape of it, bestie — copy it exactly, don't freestyle:

enum gpio_v2_line_attr_id {
    GPIO_V2_LINE_ATTR_ID_FLAGS ,
    GPIO_V2_LINE_ATTR_ID_OUTPUT_VALUES ,
    GPIO_V2_LINE_ATTR_ID_DEBOUNCE

};

---

🦋 CONSTANTS 🦋

three of them, and each one is basically pointing at a different field like "that one. use that one." 👇

• GPIO_V2_LINE_ATTR_ID_FLAGS — the flags field is in use ✨
• GPIO_V2_LINE_ATTR_ID_OUTPUT_VALUES — the values field is in use 💖
• GPIO_V2_LINE_ATTR_ID_DEBOUNCE — the debounce_period_us field is in use 🌸

ngl bestie, the whole bit is just "which union member are we talking about" — pick the constant, get the field. no cap 🧚
