Function Conversation in Autoit

[Digisoul]

Hello there;

i want to know that how can i convert this function in AutoIt ?

<code>

DWORD WINAPI PowerSetActiveScheme(

__in_opt HKEY UserRootPowerKey,

__in const GUID *SchemeGuid

);

</code>

this is my rough attempt, i want to know about __in const GUID *SchemeGuid

Func PowerSetActiveScheme($sGUID)
    ConsoleWrite("> sel: "&$sGUID&@CRLF)
    Local $tGUID = DllStructCreate($tagGUID)
    Local $pGUID = DllStructGetPtr($tGUID)
    DllCall("ole32.dll", "long", "CLSIDFromString", "wstr", '{' & $sGUID & '}', "ptr", $pGUID)
    If @error Then Return SetError(@error, @extended, 0)
    Local $res = DllCall('PowrProf.dll', "int", 'PowerSetActiveScheme', 'ptr', 0, 'ptr', $pGUID)
    ConsoleWrite($res[0] & @CRLF)
EndFunc   ;==>PowerSetActiveScheme

thanks in advance
