为什么创建的单链表输出不了？

Question

#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h>
#include<stdlib.h>
typedef struct Node {
    char data;
    struct Node* next;
}Node, * LinkList;
//初始化
InitList(LinkList L)
{
    L = (LinkList)malloc(sizeof(LinkList));
    L->next = NULL;
    return L;
}
//头插
void CreateFromHead(LinkList L)
{
    Node* s;
    char c;
    int flag = 1;
    while (flag)
    {
        printf("输入数据");
        c = getchar();
        if (c != '$')
        {
            s = (Node*)malloc(sizeof(Node*));
            s->data = c;
            s->next = L->next;
            L->next = s;
        }
        else flag = 0;
    }
}

//输出
void Printlist(LinkList L)
{
    printf("该单链表的内容为：");
    L = L->next;
    while (L != NULL)
    {
        printf("%s", L->data);
        L = L->next;
    }

}

int main()
{
    LinkList L = NULL;
    L = InitList(L);
    CreateFromHead(L);
    Printlist(L);
}
