VC6.0下的错误信息：
error LNK2001: unresolved external symbol __imp__socket@12
error LNK2001: unresolved external symbol __imp__WSAStartup@8
错误原因：因为没有联接socket库ws2_32.lib。
解决办法：对于VC6.0要在porject/settings的link页面中object/library modules中添ws2_32.lib就可以了；对于Dev-C++同样在工程/工程属性的参数页面中连接器那一栏中添加库，这时必须找到库文件的目录，对于Dev-C++的对应库文件是libws2_32.a，在软件安装下lib文件夹中可以找到相应的库文件。
总结：所有运用到WinSock2的程序在编译连接时都要用的该库
