char ** SDL_GetEnvironmentVariables(SDL_Environment *env);

🎀 FUNCTION PARAMETERS 🎀

• env — the environment you wanna snoop through, bestie. that's the one you're querying. 🕵️♀️

💖 RETURN VALUE 💖

so here's what you get back, and it's lowkey a whole situation:

• a NULL terminated array of pointers to environment variables, each one formatted like "variable=value"
• OR NULL on failure — and when that happens you gotta call SDL_GetError() for more info, fr fr 😭

⚠️ important bestie warning: this is a single allocation, and you must free it with SDL_free() when you don't need it anymore. not free(), not delete, SDL_free(). periodt. 🧚
