ptp_get_vclocks_index(9)

💅 ptp_get_vclocks_index(9) — from the Kernel API Manual, bestie 🫶

okay so real talk, we're in the Kernel API Manual today and this page is literally called ptp_get_vclocks_index. yes it's a mouthful, no you don't have to say it out loud at parties. it's giving "tiny function, big responsibilities" energy and honestly? we love her for it. 🌸

---

✨ NAME ✨

ptp_get_vclocks_index — grabs, like, all the vclocks index on pclock. and heads up bestie, the caller is responsible to free the memory of vclock_index (yes, YOU, the caller — no one else is doing it for you 💀).

---

🦋 SYNOPSIS 🦋

int ptp_get_vclocks_index (int pclock_index , int **vclock_index );

---

🎀 ARGUMENTS 🎀

• pclock_index — the phc index of the ptp pclock. that's it, that's the girl. 🌈
• vclock_index — a pointer to pointer of vclock index. double pointer behavior, double pointer drama, we stan. ✨

---

👑 DESCRIPTION 👑

it returns the number of vclocks. that's the whole description. short, sweet, main character energy fr fr. 💅

• struct ptp_system_timestamp(9)
• struct ptp_clock_info(9)
• struct ptp_clock_event(9)
• scaled_ppm_to_ppb(9)

(and yes, ptp_clock_event(9) shows up in that list — twice-ish energy is just part of the source material, we don't rewrite the guest list 💀)

🫶 friendly reminder from your favorite kernel bestie: vclock_index memory? yours to free. not mine. not the kernel's. yours. don't leave her hanging.

and that's the whole page!! this one came from ./include/linux, dated October 2026, in the Kernel API Manual. mwah, go free that memory, ily, bye 💖🎀🦋
