SDL_GetAudioRecordingDevices - Get a list of currently-connected audio recording devices.

       This function is available since SDL 3.2.0.

       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.

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