Reusing C code, giving struct multiple names - c

Question

I have two header files
A.h
struct A { ... };
function declarations which use A
B.h
function declarations which use the struct A here, and have functions which also use A.
However, I want to call "A" B here. How can I do this? I want all the
functions in here use
struct B, which I want to be exactly the same as struct A since
An example of what I "want" to do, but uses defines and is probably the wrong way of doing things: (Note, it works perfectly how I want it to, but I don't think I should be using defines for this purpose, there is probably a better way of doing things)
A.h
#ifndef A_H
#define A_H
struct A {int x;};
void A_DoSomething(struct A* a);
#endif
B.h
#ifndef B_H
#define B_H
#include "A.h"
#define B A
void B_DoSomething(struct* B b) { A_DoSomething(b); }
#endif
So is there a way to do what I want without using define? I want to do this so I can reuse code. I.e., A is a linked list, B is a stack. I can completely define my stack data structure from a linked list.
EDIT: So basically B and A are equivalent, but for my B.h/B.c file, and any files using B.h, I just want to call the structure "B" and not "A"

Answer 1

I would use typedef and use 3 h-files to separate the common data structure from A and B. Something like:
MyNode.h:
#ifndef MyNode_H
#define MyNode_H
typedef struct Node
{
void *data;
struct Node *next;
} Node;
#endif
A.h:
#ifndef A_H
#define A_H
#include "MyNode.h"
typedef Node A;
/* Declare functions for implementing a linked list using type A */
#endif
B.h:
#ifndef B_H
#define B_H
#include "MyNode.h"
typedef Node B;
/* Declare functions for implementing a stack using type B */
#endif
Main.c:
#include <stdio.h>
#include "A.h"
#include "B.h"
int main(void) {
/* Here A and B can be used as types, example: */
A list = {NULL, NULL};
B stack = {NULL, NULL};
return 0;
}
