How do I refer to a typedef in a header file?

Question

I have a source file where a typedef struct is defined:

typedef struct node {
    char *key;
    char *value;
    struct node *next;
} *Node;

You can use:

typedef struct node * Node;

But I would advise against hiding the pointer in type declaration. It is more informative to have that information in variable declaration.

module.c:

#include "module.h"
struct node {
    char *key;
    char *value;
    struct node *next;
};

module.h:

typedef struct node Node;

variable declaration for pointer somewhere:

#include "module.h"
Node * myNode; // We don't need to know the whole type when declaring pointer
