Type Definition sdl2_sys::SDL_AudioDeviceID
[−]
[src]
type SDL_AudioDeviceID = Uint32;
SDL Audio Device IDs.
A successful call to SDL_OpenAudio() is always device id 1, and legacy SDL audio APIs assume you want this device ID. SDL_OpenAudioDevice() calls always returns devices >= 2 on success. The legacy calls are good both for backwards compatibility and when you don't care about multiple, specific, or capture devices.
