idpf_ptp_adjtime_nonatomic(9)

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

okay so welcome to the function page for idpf_ptp_adjtime_nonatomic, bestie 💖 this one lives in the Kernel API Manual and honestly? she's a quiet little icon. no drama, just clock math. periodt.

---

✨ NAME ✨

idpf_ptp_adjtime_nonatomic — literally just "do a non-atomic clock adjustment." that's the whole vibe. 🕰️✨

---

🌸 SYNOPSIS 🌸

int idpf_ptp_adjtime_nonatomic (struct ptp_clock_info *info , s64 delta );

look at her. two arguments. one int return. iconic behavior, ngl 💅

---

🎀 ARGUMENTS 🎀

• info — the driver's PTP info structure 🫶 like, this is her struct, the one that holds all the clock info. give her to the function and she'll know what to do.
• delta — Offset in nanoseconds to adjust the time by ⏰✨ a signed 64-bit (s64) amount of nanoseconds. that's how far you're nudging the clock, no cap.

---

🔥 RETURN 🔥

• 0 on success 🎉 slay, the adjustment happened.
• -errno otherwise 😭 i.e. anything else means something went sideways and you get a negated errno back. check it, bestie, fr fr.
