你记得到我给你的服务器端代码吗

是的，我记得你给我看过一个服务器端代码，大概是这样的：

#define _WINSOCK_DEPRECATED_NO_WARNINGS 
#include <stdio.h> 
#include <Winsock2.h> 

#pragma comment(lib, "ws2_32.lib") 

int main() { 
    WORD wVersionRequested; 
    WSADATA wsaData; 
    int err; 

    wVersionRequested = MAKEWORD(2, 2); 
    err = WSAStartup(wVersionRequested, &wsaData); 
    if (err != 0) { 
        return -1; 
    } 

    if (LOBYTE(wsaData.wVersion) != 2 || HIBYTE(wsaData.wVersion) != 2) { 
        WSACleanup(); 
        return -1; 
    } 

    SOCKET sockSrv = socket(AF_INET, SOCK_STREAM, 0); 
    SOCKADDR_IN addrSrv; 
    addrSrv.sin_family = AF_INET; 
    addrSrv.sin_addr.S_un.S_addr = htonl(INADDR_ANY); 
    addrSrv.sin_port = htons(6000); 
    bind(sockSrv, (SOCKADDR*)&addrSrv, sizeof(SOCKADDR)); 
    listen(sockSrv, 5); 

    printf("Server started.\n"); 

    SOCKADDR_IN addrClient; 
    int len = sizeof(SOCKADDR); 
    while (1) { 
        SOCKET sockConn = accept(sockSrv, (SOCKADDR*)&addrClient, &len); 
        printf("Accepted a client: %s:%d\n", inet_ntoa(addrClient.sin_addr), ntohs(addrClient.sin_port)); 
        char recvBuf[50]; 
        while (1) { 
            int nRet = recv(sockConn, recvBuf, 50, 0); 
            if (nRet <= 0) break; 
            printf("Received message: %s\n", recvBuf); 
            send(sockConn, recvBuf, strlen(recvBuf) + 1, 0); 
        } 
        closesocket(sockConn); 
        printf("A client disconnected.\n"); 
    } 

    closesocket(sockSrv); 
    WSACleanup(); 
    return 0; 
}

这段代码是一个简单的TCP服务器程序，用于监听端口并接收客户端的连接请求。一旦有客户端连接上来，服务器会打印出客户端的IP地址和端口号，并通过循环接收客户端发送过来的消息并发送回去。需要注意的是，该代码只能在Windows系统下编译和运行。
