Function SDL_GetAudioPlaybackDevices

pub unsafe extern "C" fn SDL_GetAudioPlaybackDevices(
    count: *mut i32,
) -> *mut u32
Available on crate feature dep_sdl3 only.
Expand description

Get a list of currently-connected audio playback devices.

This returns of list of available devices that play sound, perhaps to speakers or headphones (“playback” devices). If you want devices that record audio, like a microphone (“recording” devices), use SDL_GetAudioRecordingDevices() instead.

This only returns a list of physical devices; it will not have any device IDs returned by SDL_OpenAudioDevice().

If this function returns NULL, to signify an error, *count will be set to zero.

§Parameters

  • count: a pointer filled in with the number of devices returned, may be NULL.

§Return value

Returns a 0 terminated array of device instance IDs or NULL on error; call SDL_GetError() for more information. This should be freed with SDL_free() when it is no longer needed.

§Thread safety

It is safe to call this function from any thread.

§Availability

This function is available since SDL 3.2.0.
