SDL_GetGamepadGUIDForID(3)

💖 SDL_GetGamepadGUIDForID(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the man pages, where we're about to get the implementation-dependent GUID of a gamepad. yes that's a lot of words, but trust, it's giving very "look up your controller's vibe ID" and it's lowkey iconic. 🎮✨

✨ NAME ✨

SDL_GetGamepadGUIDForID — get the implementation-dependent GUID of a gamepad 🫶

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_gamepad.h>

SDL_GUID SDL_GetGamepadGUIDForID(SDL_JoystickID instance_id);

---

💅 DESCRIPTION 💅

So here's the tea: this function hands you back the GUID of a gamepad. And the best part? You can call this before any gamepads are opened. No setup era required, no opening ceremony, nothing. She's ready when you are, fr fr. 💖

---

🎀 FUNCTION PARAMETERS 🎀

• instance_id — the joystick instance ID. that's the little number that tells you which joystick we're talking about. she's the main character here, don't lose her. 👑

---

⭐ RETURN VALUE ⭐

Returns the GUID of the selected gamepad.

But listen — if you call this on an invalid index, you get back a zero GUID. Not an error message, not a crash, just... zero. a whole lot of nothing. so if your GUID comes back looking empty, that's your sign that the index you passed was not it. 💀

---

🧚 THREAD SAFETY 🧚

It is safe to call this function from any thread. no cap. every thread is welcome at this party, we don't gatekeep. 🌈

---

🦋 AVAILABILITY 🦋

This function is available since SDL 3.2.0. so if you're on something older, sorry bestie, she's not there yet. 🙈

👑 SEE ALSO 👑

• SDL_GUIDToString(3) — turn that GUID into something you can actually read, obsessed
• SDL_GetGamepads(3) — get the whole squad of gamepads at once

ok that's the whole page, and no, I did not skip a single line. every flag, every param, every caveat — all present and accounted for. periodt. 💅

Simple Directmedia Layer wrote this one, SDL 3.4.18 is the version, and this whole vibe is dated SDL_GetGamepadGUIDForID(3). mwah, go get your GUID, bestie 🍓🫶✨
