程序代码：

void Creat_Link(PList* p,int size)
{
    *p = ( PList )malloc( LEN_List );
    assert( NULL != *p);
    memset( *p, 0, LEN_ListNode );


    ( *p )->size = size;


    ( *p )->rear = ( PListNode )malloc( LEN_ListNode );
    //写成：
    //( *p )->front = ( PListNode )malloc( LEN_ListNode );
    //不是就可以了么？
    assert( NULL != ( *p )->rear );
    ( *p )->front = ( *p )->rear;//这一行是多余的吧？
    memset( ( *p )->front, 0, LEN_ListNode );


    ( *p )->rear->next = ( PlistNode )malloc( LEN_ListNode );
    assert( NULL != ( *p )->rear->next );
    ( *p )->rear = ( *p )->rear->next;//因为这一行( *p )->rear的指向已经改变了
    ( *p )->front->next = ( *p )->rear;
    memset( ( *p )->rear, 0, LEN_ListNode );
    

    ( *p )->rear->prior = ( *p )->front;
}
