STRUCT FF_TRIGGER(9)

💖 struct ff_trigger(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for <struct ff_trigger>, and it's genuinely such a lil cutie. short king energy, but it's the thing that defines what actually triggers a force-feedback effect. that's it. that's the whole gig. periodt. 💅

---

✨ NAME ✨

struct ff_trigger — defines what triggers the force-feedback effect 🎮

---

🦋 SYNOPSIS 🦋

like, here's the whole vibe, verbatim:

struct ff_trigger {
    __u16 button;
    __u16 interval;
 };

that's the entire struct. two whole fields. she's compact and she knows it. 🎀

---

🌸 Members 🌸

• button — the number of the button that triggers the effect. like, this is the button, this one right here, the one that makes the magic happen 🔥
• interval — controls how soon the effect can be re-triggered. your built-in cooldown, basically. it's giving "wait your turn bestie" ⏳
