mixInit function mixer
Initialize the SDL_mixer library.
This must be successfully called once before (almost) any other SDL_mixer function can be used.
It is safe to call this multiple times; the library will only initialize once, and won't deinitialize until MIX_Quit() has been called a matching number of times. Extra attempts to init report success.
\returns true on success, false on error; call SDL_GetError() for details.
\threadsafety It is safe to call this function from any thread.
\since This function is available since SDL_mixer 3.0.0.
