// This function loads a WAVE from the data source, automatically freeing
// that source if 'freesrc' is non-zero. For example, to load a WAVE file,
// you could do:
// sdl.LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...);
//
// If this function succeeds, it returns the given SDL_AudioSpec,
// filled with the audio data format of the wave data, and sets
// 'audio_buf' to a malloc()'d buffer containing the audio data,
// and sets 'audio_len' to the length of that audio buffer, in bytes.
// You need to free the audio buffer with SDL_FreeWAV() when you are
// done with it.
//
// This function returns NULL and sets the SDL error message if the
// wave file cannot be opened, uses an unknown data format, or is
// corrupt. Currently raw and MS-ADPCM WAVE files are supported.
