C-错误：在非结构或联合中请求成员“ ---”

Question

This question has been asked before, but from what I have seen it's all people that are misusing 'a.b' to get pointer values. I AM using 'a->b' but it is still throwing this error. Here's my code, it's meant to be a dynamic stack:

Header file:

typedef struct etCel{
    element *ele;
    struct cel *suiv;   
} cel;

typedef cel* pile;

pile init_pile();
int affiche_pile(pile *p);

.c file:

pile init_pile(pile *p){
    return NULL;
}
int affiche_pile(pile *p){
    printf("Valeurs de la pile:\n");
    while(p!=NULL){
        affiche_element(p->ele);
        printf("\n");
        p=*(p->suiv);
    }
    return 1;
}

Answer 1

typedef cel* pile;

and

int affiche_pile(pile *p){

This leads to believe that p is now a pointer to a pointer. Expand the declarations and you get

cel* *p;

So either you change the function signature to int affiche_pile(pile p) or typedef cel pile

Answer 2

pile *p is double pointer so you change your code something like this:

affiche_element((*p)->ele);

Change at other places too.
