void    * RADARDEMO_clusterTracker_create(
                            IN  RADARDEMO_clusterTracker_config * moduleConfig,
                            OUT RADARDEMO_clusterTracker_errorCode * errorCode)

{
    RADARDEMO_clusterTracker_handle * handle;
    uint16_t index;
上面这个为什么用void *以及它的参数是什么情况，我没看懂，求指教
