Hi,
the bug is that you are allocating room for only a pointer, not for a
structure of type LinkedList.
Regards,
Andreas

Subject: [Valgrind-users] Valgrind point me out invalid writes I can't
see why.
Hi!
I think I'm messing out something, but can't figure out some
invalid writes valgrind pointing me out.
I'm implementing a linked list for a server I'm writing that will store
user configuration from a file. So I did:
struct _LinkedList
{
char *key;
char *data;
struct _LinkedList *next;
struct _LinkedList *head;
};
typedef struct _LinkedList LinkedList;
int main(void)
{
LinkedList *usersettings;
usersettings =3D newLinkedList();
}
LinkedList *newLinkedList(void)
{
LinkedList *s;
/* memory allocation for LinkedList structure */
s =3D (LinkedList *)malloc (sizeof (LinkedList *));
if (!s)
return s;
/* storing list's head */
s->head =3D s; /* invalid write ???? */
s->next =3D NULL; /* invalid write ???? */
s->key =3D NULL; /* Here valgrind says it's ok (no invalid write) */
s->data =3D NULL; /* invalid write ???? */
return s;
}
Any tip or help?
thanks a lot in advance:
