Get what the system believes is the "current working directory."
Defined in <SDL3/SDL_filesystem.h>
char * SDL_GetCurrentDirectory(void);
(char *) Returns a UTF-8 string of the current working directory in platform-dependent notation. NULL if there's a problem. This should be freed with SDL_free() when it is no longer needed.
For systems without a concept of a current working directory, this will still attempt to provide something reasonable.
SDL does not provide a means to change the current working directory; for platforms without this concept, this would cause surprises with file access outside of SDL.
This function is available since SDL 3.2.0.
