C language: Releasing memory of pointers to struct

Question

Say I have declared a pointer to a struct and assign it with malloc() using this definition

typedef struct node {
    int info;
    struct node *next;
} NODE         


        

Answer 1

node1 is a pointer, meaning the value of it is the virtual memory address of the allocated struct.

Assigning node2 = node1 just copies that address.

As a result free(node1) and free(node2) are equivalent.
