C++一段声明怎么转成delphi啊，求助

[cp1982]

typedef struct tag_hw_pack
{
BYTE bPackType;
WORD wPackSize;

union
{
HW_PACK_INFO pkInfo;
HW_PACK_ACK pkAck;
HW_PACK_CMD pkCmd ;
HW_DVR_STATUS pkStatus;
} ;

tag_hw_pack()
{
int nSize = sizeof(tag_hw_pack);
memset(this,0,nSize);
wPackSize = nSize;
}
} HW_PACK_BODY;

只做个提听，union 联合体，可以用变体record代替

能不能帮我转下呢。

貌似 可以转成这样的 类 ：

type
  Rxxx = record
    bPackType :byte;
    wPackSize :WORD;
    case integer of
      0: (pkInfo  :HW_PACK_INFO;);
      1: (pkAck   :HW_PACK_ACK;);
      2: (pkCmd   :HW_PACK_CMD;);
      3: (pkStatus:HW_DVR_STATUS;);
  end;

  THW_PACK_BODY = class
  public
    xxx :Rxxx;
    constructor Create;
  end;

implementation

constructor THW_PACK_BODY.Create;
begin
  xxx.wPackSize := sizeof(Rxxx);
end;

只会这种 ，高级的不会 ...... 不知啊有转错...
