Access Item in Nested Structure in C

Question

I try to access \"next\" in another structure, but failed although i have tried many ways.

Here is the nested structure:

struct list_head {
    struct l         


        

Answer 1

list is not declared as a pointer, so you don't use the -> operator to get its members, you use the . operator:

while (d->list.next != NULL) {
}

A different fix:

typedef struct {
  char *key;
  char *value;
  struct list_head *list;
}dict_entry;

This way, your original code attempting to refer to next would compile.
