Function fermium::audio::SDL_MixAudioFormat

pub unsafe extern "C" fn SDL_MixAudioFormat(
    dst: *mut u8,
    src: *const u8,
    format: SDL_AudioFormat,
    len: u32,
    volume: c_int
)

Mix according to a format.

This works like SDL_MixAudio, but you specify the audio format instead of using the format of audio device 1. Thus it can be used when no audio device is open at all.
