PIN_GROUP(9)

💅 PIN_GROUP(9) — bestie's edition

okay so real talk: this is a page from the Kernel API Manual, and it's genuinely just a tiny one — a single macro that declares a pin group. Short and sweet, like a good group chat message. Let's get into it 🫶

---

✨ NAME ✨

PIN_GROUP — literally just: declare a pin group. That's the whole job. Iconic minimalism 💅

---

🌸 SYNOPSIS 🌸

PIN_GROUP (n , p , m );

yep, that's it. three little letters walk into a macro. no cap 🎀

---

🦋 ARGUMENTS 🦋

so here's what each of the three actually is, keep up bestie:

• n — the name of the group. it's giving "name tag at a party" — this is what the group gets called ✨
• p — an array of pins that this group consists of. like, the whole roster of pins that make up the squad 👑
• m — the mode that the pins get put into when this group is active. and here's the fun part: this can be either a single integer or an array of integers, and in the array case the mode is per pin. so one mode for everybody, or a lil individual mode for each pin, your call 🌈

ngl the per-pin mode thing is lowkey the main character detail here — don't sleep on it 👀
