    having problems with this typedef statement

    Hello , Please what does the second typedef statement do,

    };

    typedef struct listnode Listnode;
    typedef ListNode *ListNodePtr;

    what is the difference between

    ListNodePtr *sPtr;
    ListNodePtr startPtr;

    Please explain what the second Line of Code would do please
    startPtr = NULL;
    ListNodePtr *sPtr = &startPtr
