kernel 链表操作例子（list.h为从kernel source里拷过来的，注掉了一些东西，编译通过，可用）

#include "list.h" /* list.h */

typedef struct mylist{
struct list_head list;
unsigned int port;
char name[10];
}mystruct;
struct list_head head;

int main()
{
    unsigned int i = 0;
    mystruct *p = NULL;
    mystruct *entry = NULL;
    mystruct *entry2 = NULL;
   
INIT_LIST_HEAD(&head);
    p = (mystruct *)calloc(sizeof(mystruct),20);
    for(i=0;i<20;i++)
    {
        (p+i)->port = i;   
        sprintf((p+i)->name,"mylist%d",i);
        printf("(p+i)->name is %s/n", (p+i)->name);
        printf("(p+i)->port is %d/n", (p+i)->port);
        list_add(p+i,&head);
    }
        printf("/n================================/n");
#if 1
    list_for_each_entry(entry, &head, list)
    {
        printf("(p+i)->name is %s/n", entry->name);
        printf("(p+i)->port is %d/n", entry->port);
        printf("/n--------------------------------/n");
    }
#endif
        printf("/n================================/n");
    list_for_each_entry_safe(entry, entry2, &head, list)
    {
        if(11 == entry->port)
            list_del(&(entry->list));
    }
    list_for_each_entry_safe(entry, entry2, &head, list)
    {
       
        printf("(p+i)->name is %s/n", entry->name);
        printf("(p+i)->port is %d/n", entry->port);
        printf("/n--------------------------------/n");
    }
}

 

 

notes:list_del如果在list_for_each list_for_each_entry中用会出错，原因就是指针的问题，用那些safe函数没问题，因为多了一个tmp指针。
