请问ICCAVR支持链表吗？

请问ICCAVR支持链表吗？程序一直报错

#include <stdio.h>
#include <stdlib.h>
//双链表结点接构
typedef struct DNodeType
{
    unsigned char tagaddr;
    struct DNodeType *next;
    struct DNodeType *prev;
}DNode;

//创建双链表
struct DNode * DoubleList(struct DNode *head)
{
    int i=0;
    if(NULL == head)//分配头节点空间
      head=(struct DNode*)malloc(sizeof(DNode)) ;
        head->prev=NULL ;
        head->next=NULL;
    struct DNode *current=head ;
        struct DNode *temp;

                if(temp->tagaddr == NULL)         /*结束输入*/
          break;
    }

    return head;
}

错误都在链表建立这里，是不是头文件不对啊？请各路大侠指点！！

先学者把基本的错误找出改掉，比如第一个错误，恐怕与链表无关吧

C的基础没学好
typedef struct DNodeType
{
    unsigned char tagaddr;
    struct DNodeType *next;
    struct DNodeType *prev;
}DNode;

后面都是 struct DNode * ？

应该是 DNode *
