[求助]eclipse下c++编的socket

大漠

哪位大侠在eclipse下编过c++，我编的一个socket传输，但是出错，不太理解。请指点一下，谢谢！！！
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
#include <winsock2.h>
#include <winsock.h>
#define SERVPORT 3333 /*服务器监听端口号 */
#define BACKLOG 10 /* 最大同时连接请求数 */
int main()
{
int sockfd,client_fd,sin_size; /*sock_fd：监听socket；client_fd：数据传输socket */
struct sockaddr_in my_addr; /* 本机地址信息 */
struct sockaddr_in remote_addr; /* 客户端地址信息 */
if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1)
{
perror("socket创建出错！");
exit(1);
}
my_addr.sin_family=AF_INET;
my_addr.sin_port=htons(SERVPORT);
my_addr.sin_addr.s_addr = INADDR_ANY;
memset(&(my_addr.sin_zero),8,0);
if (bind(sockfd, (struct sockaddr *)&my_addr, sizeof(struct sockaddr)) == -1)
{
perror("bind出错！");
exit(1);
}
if (listen(sockfd, BACKLOG) == -1)
{
perror("listen出错！");
exit(1);
}
while(1)
{
sin_size = sizeof(struct sockaddr_in);
if ((client_fd = accept(sockfd, (struct sockaddr *)&remote_addr,&sin_size)) == -1)
{
perror("accept出错");
continue;
}
printf("received a connection from %s\n", inet_ntoa(remote_addr.sin_addr));

if (send(client_fd, "Hello, you are connected!\n", 26, 0) == -1)
{ perror("send出错！");
closesocket(client_fd);
exit(0);
}
closesocket(client_fd);
}
}
