SDL_PenID(3type)

SDL_PenID 💅

okay bestie, welcome to the SDL3 datatypes corner of the manual, where we talk about SDL_PenID — literally just SDL pen instance IDs. that's it. that's the whole vibe. ✨

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_pen.h>

typedef Uint32 SDL_PenID;

---

🌸 DESCRIPTION 🌸

So here's the tea, bestie. SDL_PenID is how SDL keeps track of which pen is which. Zero is the special one, and zero means invalid/null device — like, no pen, nothing, a ghost. 👻

These IDs are the ones that pop up in pen events whenever SDL sees input coming from a pen. And they stay consistent for as long as SDL can recognize a tool as being the same pen. 🖊️✨

But listen — if a pen's digitizer table gets physically detached from the computer, it might get a brand new ID when it gets reconnected. not because it changed, but because SDL genuinely won't know it's the same device. it's giving "who are you, stranger?" energy. 💀

and here's the part you really need to internalize: these IDs are only stable within a single run of a program. the next time you run your program, the pen's ID will likely be different — even if the hardware was never disconnected, no unplugging, nothing. fr fr. so please don't hardcode them into anything you want to survive a restart, i am begging. 🙈
