newbie question: how to compile this program ?

[neoe77]

anyone could please help me out of this:
===================my test c program====================
t1.c

#include <containers.h>
#include <list.h>

typedef struct {
int v;
char s[10];
} MyStruct;
int main(void){
List list= newList(sizeof(MyStruct));
MyStruct data;
int nb = list->lpVtbl->Add(&list,&data);
nb = list->Add(&data);
return 0;
}

==================compiler output====================

Function: Add

Synopsis

#include <containers.h>
int (*Add)(List *L1,void *data);

Description

This function adds an element at the end of the given list.

Returns

The number of elements in the list

Example:

List list;
MyStruct data;
int nb = list->lpVtbl->Add(&list,&data);

This simpler syntax is also accepted:

int nb = list->Add(&data);

============
thanks in advance.

This prototyp seems to be wrong it
is List &L1

and list.h contains some other implementation of list (more
traditional C)

what you like to have is

#include <containers.h>

typedef struct {
int v;
char s[10];
} MyStruct;

int main(void){
List list= newList(sizeof(MyStruct));
MyStruct data;

int nb = list.lpVtbl->Add(list,&data);
nb = list.Add(&data);
return 0;
}

However two times &data is probably a very bad idea....

Hi

This is a catastrophic bug in the documentation.

List is an object, not a pointer! That is why the
"->" doesn't work.

Here is a version that compiles cleanly:

#include <containers.h>

typedef struct {
int v;
char s[10];
} MyStruct;
int main(void){
List list= newList(sizeof(MyStruct));
MyStruct data;

// Note the . instead of ->

int nb = list.lpVtbl->Add(list,&data);
nb = list.Add(&data);
return 0;
}

I have updated the documentation eliminating those errors

Sorry about this
