verifying if inherited permissions is checked

[step887 6]

I would like to modify permissions on folder and then reset them.

I can do this with permissions UDF

'?do=embed' frameborder='0' data-embedContent>>

I can do this

$dirpath =  'X:\test\test\test'
Local $arr[1][3],$aPerm[1][3] = [[@UserName, 1, $GENERIC_ALL]]
Local $SID = _GetObjectOwner($dirpath)
Local $owner = _LookupAccountSid($SID)
$dacl = _GetObjectDacl($dirpath)
_MergeDaclToArray($dacl,$arr)
$out = _EditObjectPermissions($dirpath, $aPerm,1,@UserName);,
MsgBox(0,'',@error & '  ' & $OUT & @CRLF)
$out = _SetObjectPermissions($dirpath, $arr, 1,$owner, 1)

but inherit permissons is not checked

There is a function to reset tree permissions.

I do not want to reset tree permisions, unless it was already set.

I could not find a way to do this, anyone have any ideas?
