I am trying to use the linux's kernel implementation of linked list(list.h), but I keep getting the following error:- invalid type argument of -> (have 'int')
struct klist
{
int data;
struct list_head list;
};
int main()
{
int i;
struct klist *_lptr;
LIST_HEAD(klist_head);
for(i=0;i<10;i++)
{
_lptr=(struct klist*)malloc(sizeof(struct klist));
_lptr->data=i;
}
list_for_each_entry(_lptr,&klist_head,list)
{
printf("%d\n",_lptr->data);
}
}
I have compiled and run your code, there is no error reported. (gcc 4.6.3, kubuntu 12.04)
I write one below too.
#include <stdio.h>
#include <stdlib.h>
#include "list.h"
typedef struct klist{
int data;
struct list_head list;
}klist;
int main()
{
LIST_HEAD(klist_head);
/* allocate the list */
int i = 0;
klist *_lptr = NULL;
for(i = 0; i < 10; i++){
_lptr = (klist*) malloc(sizeof(klist));
_lptr->data = i;
list_add(&_lptr->list, &klist_head);
}
/* print the list */
list_for_each_entry(_lptr, &klist_head, list){
printf("%d\n", _lptr->data);
}
/* free the list */
struct list_head *pos = NULL, *temp = NULL;
list_for_each_safe(pos, temp, &klist_head){
_lptr = list_entry(pos, klist, list);
list_del(pos);
free(_lptr);
}
return 0;
}
