Function sdl2_sys::SDL_GetAudioDriver

pub unsafe extern "C" fn SDL_GetAudioDriver(
    index: c_int
) -> *const c_char

Expand description

Use this function to get the name of a built in audio driver.

The list of audio drivers is given in the order that they are normally initialized by default; the drivers that seem more reasonable to choose first (as far as the SDL developers believe) are earlier in the list.

The names of drivers are all simple, low-ASCII identifiers, like “alsa”, “coreaudio” or “xaudio2”. These never have Unicode characters, and are not meant to be proper names.

\param index the index of the audio driver; the value ranges from 0 to SDL_GetNumAudioDrivers() - 1 \returns the name of the audio driver at the requested index, or NULL if an invalid index was specified.

\since This function is available since SDL 2.0.0.
