真心请教windows下Netbios编程！！求客户端和服务器代码

[hanxing1026]

在通讯的两端：
一端设置使用NCBLISTEN命令

memset(&ncb , 0 , sizeof(NCB));
ncb.ncb_command=NCBLISTEN ;

另一端用NCBCALLNAME命令

memset(&ncb , 0 , sizeof(NCB));
ncb.ncb_command=NCBCALLNAME;

但是总是失败的；我不清楚这两个命令还要设置哪些ncb中的参量，哪位知道的指点一下吧；
现在我只能得到执行失败的ncb.ncb_retcode，一个整数，但又不知道它是什么错误；有什么函数可以得到错误的描述。

可以参看《WINDOWS网络编程技术》一书

给一份代码让你研究研究(client和server)给出你的 Email ？
