如何在c中重置链表？

#include <stdio.h>
#include <stdlib.h>

// 定义链表节点结构
struct Node {
    int data;
    struct Node* next;
};

// 重置链表函数
void resetLinkedList(struct Node** head) {
    struct Node* temp = *head;
    struct Node* nextNode;

    while (temp != NULL) {
        nextNode = temp->next;
        temp->next = NULL;
        free(temp);
        temp = nextNode;
    }

    *head = NULL;
}

// 测试代码
int main() {
    // 创建链表
    struct Node* head = (struct Node*)malloc(sizeof(struct Node));
    struct Node* second = (struct Node*)malloc(sizeof(struct Node));
    struct Node* third = (struct Node*)malloc(sizeof(struct Node));

    head->data = 1;
    head->next = second;

    second->data = 2;
    second->next = third;

    third->data = 3;
    third->next = NULL;

    // 打印原始链表
    printf("原始链表：\n");
    struct Node* temp = head;
    while (temp != NULL) {
        printf("%d ", temp->data);
        temp = temp->next;
    }
    printf("\n");

    // 重置链表
    resetLinkedList(&head);

    // 打印重置后的链表
    printf("重置后的链表：\n");
    temp = head;
    while (temp != NULL) {
        printf("%d ", temp->data);
        temp = temp->next;
    }
    printf("\n");

    return 0;
}
