C语言 socket 编写简单服务端客户端通信问题

Question

大家好，感谢你的回复。
我用c 写了一个socket通信的小程序，写好了服务端和客户端，可遇到个问题，就是每次启动客户端只能发送第一条消息，之后服务端就不能再收到消息了。
Talk is cheak , show me the code.
服务端代码：

#include<stdlib.h>
#include<WinSock2.h>
#pragma comment(lib,"ws2_32.lib")
int main(){
    WSADATA wsd;
    SOCKET sockServer;
    SOCKADDR_IN serveraddr;// 服务端套接字   该结构中包含了要结合的地址和端口号
    SOCKET sockClient;
    SOCKADDR_IN clientaddr;
    WSAStartup(MAKEWORD(2,2),&wsd);//初始化网络接口
    sockServer = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);//创建服务器socket


    if (sockServer != -1 && sockServer != INVALID_SOCKET){
        printf("Socket has been created :%d", sockServer);
    }
    else{
        printf("Socket create failed.");
        exit(0);
    }
    serveraddr.sin_addr.S_un.S_addr = htonl(INADDR_ANY);
    serveraddr.sin_family = AF_INET;
    serveraddr.sin_port = htons(6000);//绑定端口6000
    int bindInfo = bind(sockServer, (SOCKADDR*)&serveraddr, sizeof(SOCKADDR));
    char recvBuf[100];
    int len = sizeof(SOCKADDR);
    listen(sockServer, 5);//5为等待连接数
    while (1){
        sockClient = accept(sockServer, (SOCKADDR*)&clientaddr, &len);
        //接收客户端数据
        recv(sockClient, recvBuf, strlen(recvBuf)+1, MSG_PEEK);
        printf("to me:%s\n",recvBuf);
        memset(recvBuf, 0, 100);
    }
    closesocket(sockClient);
    system("pause");
    return 0;
}

客户端代码：

 #include<winsock2.h>
#include<stdio.h>
#pragma comment(lib, "ws2_32.lib")
void main()
{
    WSADATA wsaData;
    SOCKET sockClient;//客户端Socket
    SOCKADDR_IN addrServer;//服务端地址
    WSAStartup(MAKEWORD(2, 2), &wsaData);
    char message[20] = "HelloSocket!";
    //定义要连接的服务端地址
    addrServer.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");//目标IP(127.0.0.1是回送地址)
    addrServer.sin_family = AF_INET;
    addrServer.sin_port = htons(6000);//连接端口6000
    //新建客户端socket
    sockClient = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    int s = 0;
    s = connect(sockClient, (SOCKADDR*)&addrServer, sizeof(SOCKADDR));

    while (1){
        //发送数据
        int a = send(sockClient, message, strlen(message) + 1, 0);
        printf("to server:");
        scanf("%s", message);

    }
    //关闭socket
    closesocket(sockClient);
    WSACleanup();
}

求懂的高手来解答一下。
谢谢了！

应该用多线程或者多进程，，，过两天给你源代码
