I know there are at least 10 questions already about this, but they all point to something I am not doing.
In a header file I have...
typedef struct Node {
struct Node *next;
struct pgmap page;
} Node;
typedef struct linkedlist {
struct Node *head_ptr;
struct Node *tail_ptr;
} LList;
In my c file I have
struct LList mainList;
int main()
{
struct LList *root;
root = &mainList;
root->head_ptr = NULL;
root->tail_ptr = NULL;
...
}
On the root-> lines I get the dereferencing ptr... error. All the threads already on here point to a problem where people accidentally create anonymous structs, such as
typedef struct{
int a;
}; monkey
instead of
typedef struct monkey{
int a;
}; monkey
So what am I missing????
There is no type called "struct LList
". The code "typedef struct linkedlist { ... } LList;
" creates two type names: one is struct linkedlist
, and the other is just LList
(without "struct
"). You thus need to change "struct LList
" to "LList
."
