獲取本地IP

獲取本地IP地址，直接上代碼：

BOOL GetLocalPCIPAdrdr(CString& csIPAddr)
{
    BOOL bRet = FALSE;
    char szHostName[128] = {0};
    int iRet;
    WSADATA     wsaData;
    struct hostent *pHost;
    int i;
    LPCSTR psz;

    WSAStartup(MAKEWORD(2, 2), &wsaData);
    iRet = gethostname(szHostName , 128);
    if(iRet == 0)
    {
        pHost = gethostbyname(szHostName);
        for(i=0; pHost!=NULL&&pHost->h_addr_list[i]!=NULL;i++)
        {
            psz = inet_ntoa(*(struct in_addr*)pHost->h_addr_list[i]);
        }
        csIPAddr = psz;
        bRet = TRUE;
    }

    return bRet;
}
