谁能帮我看看这段代码是什么意思?

这段代码对应了CAD里的什么操作?始终弄不明白,尤其是那些函数里的参数.求哪位看出个所以然的谈谈自己的想法,感激不尽!

void SetVars(int cmd,int bpmd,int fdia, int cmddia)
{
 struct resbuf *cmdRes,*bpmdRes,*fdiaRes, *cmddias;

 cmdRes  = ads_newrb(RTSHORT);
 bpmdRes = ads_newrb(RTSHORT);
 fdiaRes = ads_newrb(RTSHORT);
 cmddias = ads_newrb(RTSHORT);

 cmdRes ->resval.rint = cmd;
 bpmdRes->resval.rint = bpmd;
 fdiaRes->resval.rint = fdia;
 cmddias->resval.rint = cmddia;

 ads_setvar("cmdecho",cmdRes);
 ads_setvar("blipmode",bpmdRes);
 ads_setvar("filedia",fdiaRes);
 ads_setvar("cmddia",cmddias);

 ads_relrb(cmdRes);
 ads_relrb(bpmdRes);
 ads_relrb(fdiaRes);
 ads_relrb(cmddias);
}

void PostAcadCommand(CString theCmdLine)
{
   CWnd * pACad = (CWnd::FromHandle(adsw_acadMainWnd()))->GetTopWindow( );

   LPARAM lParam = 0x00190001;
   int len = theCmdLine.GetLength();
   for(int i=0; i<len;i++)
   {
    pACad->ostMessage( WM_CHAR, WPARAM(theCmdLine), lParam);
   }
   return;
}

void CFrameDlg::OnOK()
{

   csPath = "D:\\1.dwg";

   SetVars(0,0,0,1);
   ads_command(RTSTR, "._tilemode", RTSTR,"0", RTNONE);
   ads_command(RTSTR,"._pspace",RTNONE);
   ads_command(RTSTR,"._insert",RTSTR,(LPCTSTR)csPath, RTSTR, "0,0,0", RTREAL,1.0,RTSTR,"",RTSTR,"",RTNONE);
   ads_command(RTSTR, "._zoom", RTSTR,"_extents", RTNONE);
   ads_printf("continue MVIEW to insert Model space viewports for output.\n");
   SetVars(1,0,1,1);
   ostAcadCommand("._mview ");

}

以上一些函数都属于ads函数，在ObjectARX中不再用了，采用了新的函数名（新旧函数对照表见adsmigr.h）

#define ads_newrb acutNewRb
#define ads_relrb acutRelRb

#define ads_setvar acedSetVar

#define ads_command acedCommand

#define ads_printf acutPrintf

这几个函数的具体用法参见doc中acutNewRb、acutRelRb、acedSetVar、acedCommand、acutPrintf、acutNewRb全局函数的用法。
