✨ NAME ✨

SDL_hid_open — Open a HID device using a Vendor ID (VID), Product ID (PID) and optionally a serial number.

like... you give it a VID and a PID and it goes and finds your device. optionally you can be extra and specify a serial number too 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_hidapi.h>

SDL_hid_device * SDL_hid_open(unsigned short vendor_id, unsigned short product_id, const wchar_t *serial_number);

---

🎀 DESCRIPTION 🎀

so here's the tea: if serial_number is NULL, the first device with the specified VID and PID is opened. that's it, that's the vibe. not the second one, not the one that looks cuter — the first one it finds. periodt ✨

ngl if u get NULL back, don't just sit there staring at it. go call SDL_GetError(). that's the whole point of it existing 🫶
