Translate small pascal to C++/C (D3|DirectX)

Hello guys would you please translate that to C++.
I need these structure to make some directX stuff with C++ Builder.
I did not found them in the directX headers.
Either you translate the thing, or if you know where they are defined
and what I should include in my C++Builder 3 project let me know.

Thanks.

what I do not know especially is the array[0..0] ?

const
  _c_dfDIKeyboard_Objects: array[0..0] of DIOBJECTDATAFORMAT = (
    (  pguid: @GUID_Key;
       dwOfs: 1;
       dwType: DIDFT_BUTTON or DIDFT_ANYINSTANCE;
       dwFlags: 0)
  );

  c_dfDIKeyboard: DIDATAFORMAT = (
      dwSize: Sizeof(c_dfDIKeyboard);
      dwObjSize: Sizeof(DIOBJECTDATAFORMAT);
      dwFlags: 0;
      dwDataSize: SizeOf(DIKEYBOARDSTATE);
      dwNumObjs: High(_c_dfDIKeyboard_Objects)+1;
      rgodf: @_c_dfDIKeyboard_Objects);

type
  DIOBJECTDATAFORMAT = record
    pguid: PGUID;
    dwOfs: DWORD;
    dwType: DWORD;
    dwFlags: DWORD;
  end;
  LPDIOBJECTDATAFORMAT = ^DIOBJECTDATAFORMAT;

  DIDATAFORMAT = record
    dwSize: DWORD;
    dwObjSize: DWORD;
    dwFlags: DWORD;
    dwDataSize: DWORD;
    dwNumObjs: DWORD;
    rgodf: LPDIOBJECTDATAFORMAT;
  end;
  LPDIDATAFORMAT = ^DIDATAFORMAT;

GUID_Key: TGUID = (D1:$55728220;D2:$D33C;D3:$11CF;D4:($BF,$C7,$44,$45,$53,$54,$00,$00));
  DIDFT_BUTTON     = $0000000C;
  DIDFT_ANYINSTANCE = $00FFFF00;

type
  DIKEYBOARDSTATE = array[0..255] of Byte;
