连接某个域名的函数是什么(或者解析某个域名的函数)????

如题,高手解救!

struct hostent FAR *gethostbyname(
const char FAR *name
);

这是获得本机IP的，将hostname改为你要解析的域名就可以将此域名解析为相应的IP
BOOL GetLocalIP(CStringArray& strLocalIPArray)
{
static BOOL bIsGet = FALSE;
WSADATA wsadata;
char hostname[255];
HOSTENT *lpHost=NULL;
struct sockaddr_in dest;
static CStringArray strIPArray;

if(!bIsGet)
{
WORD wVersionRequested;
wVersionRequested = MAKEWORD(2, 0);
if(WSAStartup(wVersionRequested, &wsadata) != 0)
return FALSE;
if(gethostname(hostname,255) != 0)
{
// ::MessageBox(AfxGetMainWnd()->m_hWnd,_T("取本机名失败！"),_T("错误"),MB_OK);
return FALSE;
}

lpHost = gethostbyname(hostname);
if(NULL == lpHost)
{
// MessageBox(AfxGetMainWnd()->m_hWnd,_T("取本机IP失败！"),_T("错误"),MB_OK);
return FALSE;
}
for(int i = 0;lpHost->h_addr_list[i] != NULL;i++)
{
CString strLocalIP;
memcpy(&(dest.sin_addr), lpHost->h_addr_list[i],
lpHost->h_length);
strLocalIP.Format(_T("%S"),inet_ntoa(dest.sin_addr));
strIPArray.Add(strLocalIP);
}
WSACleanup();
bIsGet = TRUE;
}
strLocalIPArray.RemoveAll();
for(int i=0;i<strIPArray.GetSize();i++)
{
strLocalIPArray.Add(strIPArray.GetAt(i));
}
return TRUE;
// strIP.Format(_T("%S"),inet_ntoa(dest.sin_addr));
// return TRUE;
}
