stack around the variable ‘s’ was corrupted是指针操作有什么问题吗，搞不明白

#include<stdio.h>
#include<malloc.h>

typedef struct pnode{
    int date;

    }
    else
    {
        printf("内存不足以分配malloc");
    }

        }

int main()

修改如下，供参考：

#include<stdio.h>
#include<malloc.h>
#include<stdlib.h>
#include<string.h>
#include< stdbool.h >

typedef struct pnode{
    int date;
    struct pnode *pnext;
}pnode,linklist;

void creat_list( linklist *L) //新建带头节点链表
{
    L = (pnode*)malloc(sizeof(pnode));
    if (L)
    {
        (L)->pnext = NULL;
    }
    else
    {
        printf("内存不足以分配malloc");
    }
}
bool initlist(linklist *L)//头插法链表初始化
{
    int x;
    scanf_s("%d", &x);
    pnode* newnode=0;
    pnode* tailnode = L;
    if (!L)
    {
        return false;
    }
    //if (x != 999)
    //{
        while (x != 999)
        {
            newnode = (pnode*)malloc(sizeof(pnode));
            if (newnode)
            {
                newnode->date = x;
                newnode->pnext = NULL;
                tailnode->pnext = newnode;
                tailnode = newnode;
                printf("请输入数据\n");
                scanf_s("%d", &x);
            }
            else {
                printf("空间不足以为newnode分配malloc");
            }
        }
    //}
    printf("链表初始化完毕\n");
    return true;
}
void Printf(linklist* L)//void Printf(struct linklist* L)//打印链表
{
    pnode* n;
    n = L;
    while (n->pnext)
    {
         n = n->pnext;
         printf("%d->", n->date);
    }
    printf("\n");
}
 
int main()
{
    linklist* s;
    creat_list(s); //&s
    initlist(s);   //&s
    Printf(s);     //&s
    return 0;
}

我觉得应该是先输出 然后再指向下一个吧 而且有点好奇你这个代码是怎么运行的....

void Printf(struct linklist* L)//打印链表
{
    pnode* n;
    n = L;
    while (n->pnext)
        {
            printf("%d->", n->date);
            n = n->pnext;
        }
}

不应该用&传址吗
