我这两个函数用来连接和关闭网络接口设备。建立连接的函数有IP和端口做为参数，但是断开连接的函数没有，如果我同时和多台设备建立了连接，断开的时候要怎么做才能单独的断开其中一台设备或多台而不会影响到其它的。

apiStatus __declspec(dllexport) __stdcall DrfNetConnect (CString strIp, int port)
{
CApiSocket1* m_Sock = new CApiSocket1;

if(!m_Sock->Create())
{
m_Sock->ShutDown();
m_Sock->Close();
return -1;
}
else
{
// long tempIp;
// tempIp = inet_addr(strIp);
m_Sock->strIP = strIp;
m_Sock->port = port;
}
// CString tempIp;
// tempIp = "ping " + strIp;
// if(!system(tempIp))
// return -11;

哦 我不懂哦 好像很复杂的
谁帮我改下这段代码吧
我看看具体是怎么实现就明白了
