C使用sendto发送多种数据类型

#include<stdio.h>
#include <stdlib.h>
#include<string.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

int main() {
    int sockfd;
    struct sockaddr_in servaddr;
    char buffer[1024];
    char message[] = "Hello, this is a message from client!";
    int age = 25;
    float height = 175.5;

    sockfd = socket(AF_INET, SOCK_DGRAM, 0);

    memset(&servaddr, 0, sizeof(servaddr));
    servaddr.sin_family = AF_INET;
    servaddr.sin_port = htons(12345);
    servaddr.sin_addr.s_addr = inet_addr("127.0.0.1");

    // 将数据类型转换为字节流
    memcpy(buffer, &message, sizeof(message));
    memcpy(buffer + sizeof(message), &age, sizeof(age));
    memcpy(buffer + sizeof(message) + sizeof(age), &height, sizeof(height));

    // 发送数据
    sendto(sockfd, buffer, sizeof(message) + sizeof(age) + sizeof(height), 0, (struct sockaddr *)&servaddr, sizeof(servaddr));

    close(sockfd);
    return 0;
}
