标题: 位置公差中ProMdlGtolVisit为何用不了？
我用的是TestGtol.C作为例子，
可是却无法遍历到模型中所有的几何位置公差？
如下所示，问题就出在ProMdlGtolVisit上：
ProError TestGtolCollect(ProMdl mdl, ProGtol **gtol)
{
   &nbsp

roGtol *tmp_gtol = NULL;
   &nbsp

roError error;
// &nbsp

roAppData app_data;

.23
    
    if((gtol==NULL)||(mdl==NULL))
        return(PRO_TK_BAD_INPUTS);

/*--------------------------------------------------------------------*\
    Alloc memory for gtol array.
\*--------------------------------------------------------------------*/
    error = ProArrayAlloc(0, sizeof(ProGtol),1,(ProArray*)[$tmp_gtol)]
    TEST_CALL_REPORT ("

roArrayAlloc()",
            "TestGtolCollect()", error, error != PRO_TK_NO_ERROR);

   TEST_CALL_REPORT ("

roArrayAlloc()",
            "TestGtolCollect()", error, error != PRO_TK_NO_ERROR);*/

    
    if(error!=PRO_TK_NO_ERROR)
        return(error);

        
/*--------------------------------------------------------------------*\
    Visit and add all gtol from the specified model.
\*--------------------------------------------------------------------*/
    error = ProMdlGtolVisit(mdl,(ProGtolVisitAction)TestGtolCollectVisit,
       (ProGtolFilterAction)PRO_TK_NO_ERROR,(ProAppData)[$tmp_gtol)]
    TEST_CALL_REPORT ("ProMdlGtolVisit()",
            "TestGtolCollect()", error, error != PRO_TK_NO_ERROR);

/*--------------------------------------------------------------------*\
    If error then free memory.
\*--------------------------------------------------------------------*/
    if(error!=PRO_TK_NO_ERROR)
    {
        if(tmp_gtol!=NULL)
        {
            error=ProArrayFree((ProArray*)[$tmp_gtol)]
            TEST_CALL_REPORT ("ProArrayFree()",
                "TestGtolCollect()", error, error != PRO_TK_NO_ERROR);
            tmp_gtol = NULL;
        }
        return(error);
    }

   error = ProArrayObjectAdd((ProArray*)[$tmp_gtol,PRO_VALUE_UNUSED,1,gtol)]

.2 add
   TEST_CALL_REPORT ("ProArrayObjectAdd()",
          "TestGtolCollectVisit()", error, error != PRO_TK_NO_ERROR);

.2 add
    
    *gtol = tmp_gtol;
  
  return(PRO_TK_NO_ERROR);
}
