大家帮帮忙啊：怎么得到远程链接的IP地址？？

Question

int getpeername(
  SOCKET s,                    
  struct sockaddr FAR *name,  
  int FAR *namelen            
);

Answer 1

一个基于SERVICE的IP记录程序                       作者：病毒此程序运行后将自身注册成一个SERVICE，每次开机自动启动，采用异步SOCKET
方式监听102端口，将所有访问着的IP记录在特定的日志文件中。这原本是单位
项目中的模块，现改动后拿出来让初学着学习NT SERVICE编程。
（SDK程序VC，BCB等WIN下的C编译器均可编译）

Answer 3

to    masterz() :  
　　　s 参数是已经连接的SOCKET的句柄，还是监听句柄？在VC中可以直接调用这个函数吗？可以在OnReceive函数中调用吗？

thanks ,不过还有一些地方没懂，不知可否信件讨论，我的信箱是
