💅 icss_iep_get_ptp_clock_idx(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes, the actual kernel API manual, and yes, you're gonna understand this one, i promise 🫶 this page is literally about icss_iep_get_ptp_clock_idx, and no cap it's a tiny little function that just tells you which PTP clock you're working with. it's giving "one job, does it well" energy ✨

---

✨ NAME ✨

icss_iep_get_ptp_clock_idx — the function that gets you the PTP clock index, using the IEP driver 💖

like, that's it. that's the whole vibe. she asks the IEP driver "hey, which PTP clock is this?" and the driver answers. iconic behavior honestly.

---

🌸 SYNOPSIS 🌸

int icss_iep_get_ptp_clock_idx (struct icss_iep *iep );

so it returns an int, and it takes exactly one thing: a struct icss_iep * that's literally named iep. short, sweet, slays 💅

---

🎀 ARGUMENTS 🎀

• iep — a pointer to the structure that represents the IEP. that's the whole argument. one pointer, no drama, no surprises. you hand her the IEP struct and she's off 🦋

---

⭐ RETURN ⭐

the PTP clock index 🎉 — that's your answer, that's what you came for.

and if it's not registered? she returns -1. yep. not registered = -1, no exceptions, don't @ me 😭

ok genuine heads up: if that index comes back as -1, that's the "not registered" signal. don't go treating -1 like a valid clock index, that's the trap 🙈
