使用udp协议可以给自己的电脑主机发送消息

#include <stdio.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <netinet/in.h>
#include <unistd.h>
#include <string.h>
int main(int argc, char const *argv[])
{
    //1.创建套接字
    int sdf = socket(AF_INET,SOCK_DGRAM,0);
    if(sdf == -1)
    {
        perror("socket");
        return -1;
    }
    printf("socket创建成功\n");
    //2.定义目标主机的ip地址和端口号
    struct sockaddr_in dstaddr;
    dstaddr.sin_family = AF_INET;
    dstaddr.sin_addr.s_addr = inet_addr("10.12.152.137");
    dstaddr.sin_port = htons(8080);

    char buf[128] = "卡是卡卡洒家洒家";
    for(int i = 0;i < 10;i++)
    {
        ssize_t len = sendto(sdf,buf,strlen(buf),0,(struct sockaddr *)&dstaddr
        ,sizeof(dstaddr));

        if(len != -1)
        {
            printf("发送数据成功\n");
        }
        sleep(1);
    }
    close(sdf);
    return 0;
}
