Overview
This returns of list of available devices that record audio, like a microphone ("recording" devices). If you want devices that play sound, perhaps to speakers or headphones ("playback" devices), use
SDL_GetAudioPlaybackDevices () 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.
Function parameters
- count
-
a pointer filled in with the number of devices returned, may be NULL.
Return value
( SDL_AudioDeviceID
*) Returns a 0 terminated array of device instance IDs, or NULL on failure; 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.
