STRUCT IMG_IR_FILTER(9)

💅 struct img_ir_filter(9)

okay bestie, welcome to the Kernel API Manual ✨ — section 9, struct edition. this one is about struct img_ir_filter, and its whole ~vibe~ is filtering IR events. that's it, that's the job. let's get into it 🎀

---

🌸 NAME 🌸

struct img_ir_filter — Filter IR events. literally what it says on the tin, no cap 💖

---

✨ SYNOPSIS ✨

struct img_ir_filter {
    u64 data;
    u64 mask;
    u8 minlen;
    u8 maxlen;
};

that's the whole struct, she's compact and iconic 👑

---

🦋 Members 🦋

• data — the data to match. this is the thing you're out here looking for, fr fr 🔍
• mask — mask of bits to compare. like, which bits of data actually matter here 💅
• minlen — additional minimum number of bits. the floor, the bare minimum, we do not go below this 🚫
• maxlen — additional maximum number of bits. the ceiling, the limit, the "know your worth" of bit counts ⭐

ngl all four members are just sitting there doing their thing — data and mask are u64, minlen and maxlen are u8. don't mix them up bestie 🙈
