Implementation

IMMDeviceCollection? enumAudioEndpoints(

  final ppDevices = adaptiveCalloc<VTablePointer>();
  final hr$ = HRESULT(
    _EnumAudioEndpointsFn(ptr, dataFlow, dwStateMask, ppDevices),
  );
  if (hr$.isError) {
    free(ppDevices);
    throw WindowsException(hr$);
  }
  final result$ = ppDevices.value;
  free(ppDevices);
  if (result$.isNull) return null;
  return .new(result$);
