linux端：

#define MYPORT 3333
#define BACKLOG 10
main()
{
 int sockfd, new_fd;

 int sin_size;
 if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
    perror("socket");
    exit(1);
 }
 my_addr.sin_family = AF_INET;
 my_addr.sin_port = htons(MYPORT);
 my_addr.sin_addr.s_addr = htonl(INADDR_ANY);
 bzero(&(my_addr.sin_zero),0);
 if (bind(sockfd, (struct sockaddr *)&my_addr, sizeof(struct sockaddr))== -1) {
    perror("bind");
    exit(1);
 }
 if (listen(sockfd, BACKLOG) == -1) {
    perror("listen");
    exit(1);
 }

    perror("accept");
    continue;
 }
 printf("server: got connection from %s\n",inet_ntoa(their_addr.sin_addr));
 if (!fork()) {
 if (send(new_fd, "Hello, world!\n", 14, 0) == -1)
 perror("send");
 close(new_fd);
 exit(0);
 }
 close(new_fd);
 while(waitpid(-1,NULL,WNOHANG) > 0);
 }
}
