SDL_HINT_HIDAPI_UDEV(3)

💖 SDL_HINT_HIDAPI_UDEV 💖

okay bestie, gather round, because we're talking about a lil hint macro from the SDL3 functions squad — SDL_HINT_HIDAPI_UDEV — and it's literally the switch that decides whether HIDAPI does udev-based device detection or just vibes and polls. no cap. 🌸

It's a variable, it's a hint, it controls whether HIDAPI uses udev for device detection. that's the whole job. she's simple, she's iconic, she's doing the most with the least. 💅

✨ SYNOPSIS ✨

#include <SDL3/SDL_hints.h>

#define SDL_HINT_HIDAPI_UDEV "SDL_HIDAPI_UDEV"

yes bestie, that's the include, that's the macro, that's the string value "SDL_HIDAPI_UDEV". copy it exactly, don't freestyle it, I am begging. 🙈

---

🦋 DESCRIPTION 🦋

so the way this works is: you set the variable, and it can be one of these two values:

• "0" — HIDAPI will poll for device changes. like, she's out here checking constantly. hustle energy, no shortcuts. ⭐
• "1" — HIDAPI will use udev for device detection. (this is the default, bestie — the main character setting) 👑

⚠️ real talk though: this hint should be set before SDL is initialized. if you set it after, that's on you, and it's giving "too late". don't do that. 💀

---

🌈 AVAILABILITY 🌈

this hint is available since SDL 3.2.0. if you're on something older, she does not exist, she has not been born yet, it's not a vibe check she can pass. 😭
