помогите разобратся что тут к чему:
| Код |
program shut;
{$APPTYPE CONSOLE}
uses
SysUtils,
Windows;
var
logoff: Boolean = False;
reboot: Boolean = False;
warn: Boolean = False;
downQuick: Boolean = False;

powerOff: Boolean = False;
timeDelay: Integer = 0;
function HasParam(Opt: Char): Boolean;
var
x: Integer;
begin
Result := False;
for x := 1 to ParamCount do
if (ParamStr(x) = '-' + opt) or (ParamStr(x) = '/' + opt) then Result := True;
end;
function GetErrorstring: string;
var
lz: Cardinal;
err: array[0..512] of Char;
begin
lz := GetLastError;
FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM, nil, lz, 0, @err, 512, nil);
Result := string(err);
end;
procedure DoShutdown;
var
rl, flgs: Cardinal;

if downQuick then flgs := flgs or EWX_FORCE;
if not reboot then flgs := flgs or EWX_SHUTDOWN;

if logoff then flgs := (flgs and (not (EWX_REBOOT or EWX_SHUTDOWN or EWX_POWEROFF))) or
EWX_LOGOFF;
if Win32Platform = VER_PLATFORM_WIN32_NT then
begin
if not OpenProcessToken(GetCurrentProcess, TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY,
hToken) then
Writeln('Cannot open process token. [' + GetErrorstring + ']')
else

end
