STRUCT I3C_CCC_GETPID(9)

💅 struct i3c_ccc_getpid(9) — from the Kernel API Manual, bestie ✨

okay so picture this: it's a kernel API manual page, it's giving very serious low-level energy, and it's literally all about one lil struct. no cap. let's get into it 🫶

---

🌸 NAME 🌸

struct i3c_ccc_getpid — the payload you pass to the GETPID CCC 💖 (yes that's the whole vibe, it's a payload struct, that's her job, she's iconic for it)

---

✨ SYNOPSIS ✨

struct i3c_ccc_getpid {
    u8 pid[6];
};

that's it. that's the whole struct. six bytes of pure main character energy 🎀

---

🦋 Members 🦋

• pid — the 48-bit PID, stored in big endian (so like... most significant byte first, periodt 💅). 48 bits = 6 bytes, which is exactly why the array is pid[6], the math is mathing and we love to see it ✨

no gatekeeping here, they're all one big happy header file 💜

bestie moment: pid[6] is u8, so like don't go thinking it's some fancy wide type, it's just six lil bytes. big endian though. respect the byte order or else 😤

okay that's the entire page, we ate and left no crumbs 👑 stay hydrated, go read your CCC headers, and remember — this whole thing came from ./include/linux/i3c, dated October 2026, so shoutout to that source and that month fr fr 🍓💖 mwah, love u, bye! 🧚
