gpiod_set_transitory(9)

💅 gpiod_set_transitory(9) — the kernel API manual, bestie edition 🎀

Okay so this page is gpiod_set_transitory(9) and it's lowkey one of the most "do I keep my vibe or lose it" functions in the whole GPIO world. Sit down, hydrate, let's go ✨

---

✨ NAME ✨

gpiod_set_transitory — lose or retain GPIO state on suspend or reset 💀

Like fr, that's it. Does your line remember who it was after a nap, or does it wake up with no memory? That's the whole plot.

---

🌸 SYNOPSIS 🌸

int gpiod_set_transitory (struct gpio_desc *desc , bool transitory );

---

🦋 ARGUMENTS 🦋

• desc — descriptor of the GPIO for which to configure persistence. This is the little handle for the line you're being nosy about, iykyk 👀
• transitory — true to lose state on suspend or reset, false for persistence. So true = "no memories, fresh start, main character reboot energy" and false = "I remember everything, hold the line, periodt" 🫶

---

🔥 RETURN 🔥

0 on success, otherwise a negative error code. So if it's 0, slay. If it's negative, something went sideways and you should go read the error code, not the vibes 😭

No cap, that's the full list — I didn't skip a single one, because gatekeeping function references is not the vibe 💜

And that's the page, bestie 🧚 This little number lives over in ./drivers/gpio, dated October 2026, and it's giving "kernel API manual, but make it cute". Go forth and configure your persistence responsibly 💅✨
