Deinitialize the SDL_mixer library.
Defined in <SDL3_mixer/SDL_mixer.h>
void MIX_Quit(void);This must be called when done with the library, probably at the end of your program.
It is safe to call this multiple times; the library will only deinitialize once, when this function is called the same number of times as MIX_Init was successfully called.
Once you have successfully deinitialized the library, it is safe to call MIX_Init to reinitialize it for further use.
On successful deinitialization, SDL_mixer will destroy almost all created objects, including objects of type:
...which is to say: it's possible a single call to this function will clean up anything it allocated, stop all audio output, close audio devices, etc. Don't attempt to destroy objects after this call. The app is still encouraged to manage their resources carefully and clean up first, treating this function as a safety net against memory leaks.
It is safe to call this function from any thread.
This function is available since SDL_mixer 3.0.0.
