多种语言socket编程集锦—win32

原文http://www.blogjava.net/huyi2006/articles/263831.html

借此地方整理以下socket编程的多种语言的实现，socket可以跨平台的通信，因此多语言、多平台下的实现有必要了解的。代码都是源自网上，感谢网友的分享。

socket编程在windows下的C语言实现，dev C++下编译通过
编译时设置编译选项 工具-->编译选项-->编译器，勾选在连接器命令行加入以下命令，在对话框中填-lwsock32
//server.c

int main()

    WORD wVersionRequested;
    WSADATA wsaData;
    int err;
    
    wVersionRequested = MAKEWORD( 1, 1 );
    
    err = WSAStartup( wVersionRequested, &wsaData );
    if ( err != 0 ) {
        return;
    }
    
    if ( LOBYTE( wsaData.wVersion ) != 1 ||
    HIBYTE( wsaData.wVersion ) != 1 ) {
        WSACleanup();
        return;
    }
    SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,0);
