单链表有关问题

单链表问题！
请问各位高手，单链表用指针如何实现数据的逆向输出，谢谢！

[解决办法]
_list{
int data;
list *link;
};

typedef list *Link;

Link invertList(Link currentPtr){
Link pointer;
Link back;
Link next;

back=currentPtr;
pointer=back-> link;
back-> link=NULL;

next=pointer-> link;
pointer-> link=back;
back=pointer;
pointer=next;

while(pointer-> link!=NULL){
next=pointer-> link;
pointer-> link=back;
back=pointer;
pointer=next;
}

pointer-> link=back;
currentPtr=pointer;
return currentPtr;
}
