为什么getdate()函数无法用？请大家帮忙

刚刚开始用c来编程，现在想取系统日期：  
   
  #include   <dos.h>    
  #include   <stdio.h>    
   
  int   main(void)    
  {    
        struct   date   d;    
   
        getdate(&d);    
        printf("The   current   year   is:   %d\n",d.da_year);    
        printf("The   current   day   is:   %d\n",d.da_day);    
        printf("The   current   month   is:   %d\n",d.da_mon);    
        return   0;    
  }  
   
  用Microsoft   Visual   C++   6.0进行开发。为什么此段程序编译不通过，报  
  error   C2079:   'd'   uses   undefined   struct   'date'  
  warning   C4013:   'getdate'   undefined;   assuming   extern   returning   int  
  error   C2224:   left   of   '.da_year'   must   have   struct/union   type  
  error   C2224:   left   of   '.da_day'   must   have   struct/union   type  
  error   C2224:   left   of   '.da_mon'   must   have   struct/union   type  
   
  难道getdate不在<dos.h>中的吗？  
   
  请大家帮忙。谢谢！ 问题点数：20、回复次数：1Top

用VC应该用GetDateTime  
       
    Platform   SDK:   Windows   Management   Instrumentation    
  CInstance::GetDateTime  
  The   GetDateTime   method   returns   a   datetime   property.  
   
  bool   GetDateTime(  
      LPCWSTR   name,  
      WBEMTime&   wbemtime  
  );  
   
  Parameters  
  name    
  Name   of   the   datetime   property   retrieved.    
  wbemtime    
  Buffer   to   receive   the   datetime   property.    
  Return   Values  
  Returns   TRUE   if   the   operation   was   successful   and   FALSE   if   an   attempt   was   made   to   retrieve   a   property   that   is   not   a   datetime   value   or   a   property   that   does   not   exist.   More   information   is   available   in   the   log   file,   Framework.log.  
   
  Requirements  
  Client:   Included   in   Windows   XP,   Windows   2000   Professional,   Windows   NT   Workstation   4.0   SP4   and   later,   Windows   Me,   Windows   98,   and   Windows   95.  
  Server:   Included   in   Windows   Server   2003,   Windows   2000   Server,   and   Windows   NT   Server   4.0   SP4   and   later.  
  Header:   Declared   in   Instance.h;   include   FwCommon.h.  
  Library:   Use   Framedyn.lib.  
   
   
  Platform   SDK   Release:   February   2003     What   did   you   think   of   this   topic?  
      Order   a   Platform   SDK   CD
