[求助]：匿名块

xulpec

我想建立一个匿名块，然后画一条线(pt1,pt2)加入到块。可是执行到entlist = acutBuildList(RTDXF0, "LINE",10,pt1,10, pt2,0); 出现错误。

代码如下
entlist=acutBuildList(RTDXF0,"BLOCK",2,"*ANON",10,"1",0);
if(entlist==NULL)
{acdbFail("建立链表失败!");
return ;
}
status=acdbEntMake(entlist);
acutRelRb(entlist);
if(status!=RTNORM)
{acdbFail("建立块失败!");
return ;
}
entlist = acutBuildList(RTDXF0, "LINE",10,pt1,10, pt2,0);
if (entlist == NULL) {
    acdbFail("Unable to create result buffer list\n");
    return ;
}
status = acdbEntMake(entlist);
acutRelRb(entlist); // Release acdbEntMake buffer.
if (status == RTERROR) {
    acdbFail("Unable to make circle entity\n");
    return ;
}
