c语言中结构体可以作为引用传递吗？如果可以为什么以下程序老出错（来自严蔚敏的数据结构）！急求
如题代码如下
希望那个高手帮忙解决其中错误

#include<stdio.h>
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10
typedef struct Wsqlist
{
int* elem;
int length;
int listsize;
}Sqlist ;

int Initlist_Sq(Sqlist& Li);
int ListInsert_Sq(Sqlist& L,int i,int e);
int ListDelete_Sq(Sqlist& L,int i,int &e);

int Initlist_Sq(Sqlist& Li)
{
Li.elem=(int *) malloc(sizeof(int)*LIST_INIT_SIZE );
printf("OK!\n");
if(Li.elem==NULL) exit(1);
Li.length = 0;
Li.listsize = LIST_INIT_SIZE;
printf("OK!\n");
return 0;
}
int ListInsert_Sq(Sqlist& L,int i,int e)
{
int *p,*q;
if(i<1||i>L.length+1) exit(1);
if(L.length>=L.listsize)
{
int *newbase;
newbase = (int *)realloc(L.elem,sizeof(int)*(L.listsize+LISTINCREMENT));
if(!newbase) exit(1);
L.elem = newbase;
L.listsize+=LISTINCREMENT;
}
if(L.length==0)
L.elem[0]= e;
else
{
q = &(L.elem[i-1]);
for(p=&(L.elem[L.length-1]);p>=q;--p)
*(p+1) = *p;

*q = e;
}
++L.length;
return 0;
}

int ListDelete_Sq(Sqlist& L,int i,int &e)
{
int *p,*q;
if(i<1||i>L.length+1) exit(1);
p = &(L.elem[i-1]);
e = *p;
q = L.elem+L.length-1;
for(;p<q;++p) *p = *(p+1);
--L.length;
return e;
}
int main()
{
Sqlist list;
int m=0,n=0;
Initlist_Sq(list);
ListInsert_Sq(list,1,12);
m = ListDelete_Sq(list,1,&n);
printf("%d\n",list.length);
getch();
return 0;
}

------解决方案--------------------
不可以，因为C中根本没有引用。呵呵

如果在C++中，结构体是可以有引用的
