gpiod_set_config(9)

📦 version 7.3.1, in nixpkgs unstable

💅 gpiod_set_config(9) — the "just set the config already" era

okay bestie, welcome to the Kernel API Manual ✨ this one lives in the kernel GPIO world and it's genuinely so niche and so cute. Let's get into it.

🌸 NAME 🌸

gpiod_set_config — sets @config for a GPIO 🎀

✨ SYNOPSIS ✨

int gpiod_set_config (struct gpio_desc *desc , unsigned long config );

like yes that's the whole signature, no cap 💅

🦋 ARGUMENTS 🦋

  • desc — the descriptor of the GPIO for which to set the configuration. it's giving "the main character of this function" 👑
  • config — same packed config format as generic pinconf, fr fr. don't invent your own format bestie, use the packed one 🎀

💖 RETURN 💖

  • 0 on success — slay, it worked ✨
  • -ENOTSUPP if the controller doesn't support setting the configuration — like when the hardware is just not having it today, and honestly same 😭
ngl, -ENOTSUPP is not an error you caused, it's the controller saying "that's not something I do" — vibe check failed on the hardware side, not yours 💀

🌈 SEE ALSO 🌈

the way this list is so long — the kernel devs really said "let me link literally everything" and honestly? iconic. every single one, in order, no skips:

that's the whole thing bestie, go forth and configure responsibly 💜
