应该使用什么API函数得到本机当前登录到域的域名，注意，不是所属的域名

如题

type

下面的函数获取域名：

function GetDomainName: AnsiString;
type

wkui1_logon_domain: PChar;
wkui1_logon_server: PChar;

谢谢斑竹~！

我是这么写的

PWKSTA_USER_INFO_1 = ^WKSTA_USER_INFO_1;
WKSTA_USER_INFO_1 = record
wkui1_username:PWideChar;
wkui1_logon_domain:PWideChar;
wkui1_oth_domains:PWideChar;
wkui1_logon_server:PWideChar;
end;
function NetWkstaUserEnum( servername:PWideChar; level:DWORD; var bufptr:Pointer;
prefmaxlen: DWORD; var entriesread, totalentries, resumehandle:DWORD ): DWORD; stdcall;
external 'NETAPI32.DLL' name 'NetWkstaUserEnum';

function NetApiBufferFree( bufptr:Pointer ): DWORD; stdcall; external 'NETAPI32.DLL' name 'NetApiBufferFree';
。。。。。。。。。

procedure TForm1.Button1Click(Sender: TObject);
VAR
wui:PWKSTA_USER_INFO_1;
//进行列举 dwPrefMaxLen:cardinal;
dwEntriesRead:cardinal;
dwTotalEntries:cardinal;
dwResumeHandle:cardinal;
rc: dword;
begin
dwPrefMaxLen := $FFFFFFFF;
dwEntriesRead := 0;
dwTotalEntries := 0;
dwResumeHandle := 0;

rc := NetWkstaUserEnum( nil, 1, pointer(wui), dwPrefMaxLen, dwEntriesRead,
dwTotalEntries, dwResumeHandle );

label1.caption:=wui.wkui1_username;
label2.caption:=wui.wkui1_logon_domain;
end;
后来得到的域名不对~~
