Question

Here is the struct I am using for the nodes...

typedef struct
{
    struct Node* next;
    struct Node* previous;
    void* data;
} Node;

and h

Answer 1

Defining typedef of struct in C is best done before the struct declaration itself.

typedef struct Node Node; // forward declaration of struct and typedef

struct Node
{
    Node* next;          // here you only need to use the typedef, now
    Node* previous;
    void* data;
};
