Function sdl2_sys::SDL_OpenAudioDevice

pub unsafe extern "C" fn SDL_OpenAudioDevice(
    device: *const c_char, 
    iscapture: c_int, 
    desired: *const SDL_AudioSpec, 
    obtained: *mut SDL_AudioSpec, 
    allowed_changes: c_int
) -> SDL_AudioDeviceID

Open a specific audio device. Passing in a device name of NULL requests the most reasonable default (and is equivalent to calling SDL_OpenAudio()).

The device name is a UTF-8 string reported by SDL_GetAudioDeviceName(), but some drivers allow arbitrary and driver-specific strings, such as a hostname/IP address for a remote audio server, or a filename in the diskaudio driver.

\return 0 on error, a valid device ID that is >= 2 on success.

SDL_OpenAudio(), unlike this function, always acts on device ID 1.
