gpiod_disab...timestamp_ns(9)

💅 gpiod_disable_hw_timestamp_ns(9) — bestie edition

okay so this is a page from the Kernel API Manual, and before you panic at the truncated title: yes, it's gpiod_disable_hw_timestamp_ns(9). The header just refuses to spell the whole thing out because it's dramatic like that. 😭

---

✨ NAME ✨

gpiod_disable_hw_timestamp_ns — literally just "Disable hardware timestamp." That's it. That's the whole vibe. She turns the hardware timestamping off, and she does it with her whole chest. 🎀

---

🌸 SYNOPSIS 🌸

int gpiod_disable_hw_timestamp_ns (struct gpio_desc *desc , unsigned long flags );

look at her. returns an int, takes a struct gpio_desc * and an unsigned long. so organized. 💅

---

🦋 ARGUMENTS 🦋

• desc — the GPIO you want to disable. this is the main character of the operation, the line in question, the one getting un-timestamped. ✨
• flags — flags related to the GPIO edge, and here's the thing: you pass the same value as you used during the enable call. same value. not "close enough" value. not "I kinda remember" value. same. iykyk 🫶

---

💖 RETURN 💖

0 on success, or a negative errno on failure. no cap — if you get anything below zero, something went sideways and you should go read your errno. 🔥

👑 SEE ALSO 👑

this list is LONG, bestie. she ate and left no crumbs. every single reference, verbatim, coming right up. 🌈

so anyway, this page lives in ./drivers/gpio, and it's dated October 2026, which is giving time traveler energy ngl. bookmark it, cite it, live laugh love it. mwah 💜🦋⭐
