SDL_HINT_EVDEV_DEVICES(3)

💖 NAME 💖

SDL_HINT_EVDEV_DEVICES — a lil variable that holds a whole list of evdev devices to use when udev isn't available. bestie, it's the backup plan ✨

(oh and hey, this whole page lives in the SDL3 FUNCTIONS manual, section 3, iykyk 🫶)

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_hints.h>

#define SDL_HINT_EVDEV_DEVICES "SDL_EVDEV_DEVICES"

---

🦋 DESCRIPTION 🦋

okay so the list of devices? it's giving this format exactly:

deviceclass:path[,deviceclass:path[,...]]

and let's break that down fr fr:

• deviceclass is an integer that represents the SDL_UDEV_deviceclass — yes, an integer, no vibes-based guessing 💅
• path is the full path to the event device. the full path. all of it. 👑

and you can chain as many deviceclass:path pairs as you want, separated by commas — the [,...] is literally telling you "yeah keep going, add more" 🔥

⚠️ set this hint before SDL is initialized. like, before. not during, not after, not mid-init while you're distracted by a snack. before. no cap. 🙈

---

⭐ AVAILABILITY ⭐

this hint has been around since SDL 3.2.0 — so if you're on anything older, it's not ghosting you, it just doesn't exist yet 😭

made with love by the Simple Directmedia Layer crew, currently serving SDL 3.4.18 💜 — go forth and enumerate those event devices, you absolute icon 👑✨
