SDL_GetJoystickGUIDInfo(3)

✨ SDL_GetJoystickGUIDInfo ✨

okay bestie, so this is a page from the SDL3 FUNCTIONS manual (that's the SDL_GetJoystickGUIDInfo(3) one, in case the header didn't tip you off 💅) and we're about to decode a whole controller's identity from one little struct. no cap.

---

🎀 NAME 🎀

SDL_GetJoystickGUIDInfo</purl> — get the device information encoded in a SDL_GUID structure. it's giving detective work but make it ✨silicon✨

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_joystick.h>

void SDL_GetJoystickGUIDInfo(SDL_GUID guid, Uint16 *vendor, Uint16 *product, Uint16 *version, Uint16 *crc16);

---

💖 FUNCTION PARAMETERS 💖

• guid — the SDL_GUID you wish to get info about. your main character. the one we're interrogating 🕵️♀️
• vendor — a pointer filled in with the device VID, or 0 if not available.
• product — a pointer filled in with the device PID, or 0 if not available.
• version — a pointer filled in with the device version, or 0 if not available.
• crc16 — a pointer filled in with a CRC used to distinguish different products with the same VID/PID, or 0 if not available. yes bestie, sometimes two devices share a VID and a PID and this is the lil tiebreaker 🔥
