Documentation says that the size of 'ptr' with DllStructCreate() is 4 bytes and unlike with, for example, 'int_ptr' there is no mention of differences when x64 AutoIt is used. I would assume it's the same thing with other alike types.

$tStructure = DllStructCreate("ptr")
$iSize = DllStructGetSize($tStructure)

ConsoleWrite("Size of ptr = " & $iSize & " bytes" & @CRLF)
MsgBox(64, "ptr", "Size = " & $iSize)

With new 3.3.2.0 version there are issue(s) with data types with DllCall() function. If I ask for dword AutoIt returns int. For example:

$sFile = "NonExistingFile"

$aCall = DllCall("kernel32.dll", "dword", "CreateFileW", _
		"wstr", $sFile, _
		"dword", 0x80000000, _ ; GENERIC_READ
		"dword", 0, _ ; prevent sharing
		"ptr", 0, _
		"dword", 3, _ ; OPEN_EXISTING
		"dword", 0, _
		"ptr", 0)

$hFile = $aCall[0]

ConsoleWrite("! " & $hFile & @CRLF)
MsgBox(0, '$hFile is', $hFile & @CRLF)

Same thing is for any parameter. If I do "dword*", 0 , i get int value returned. I could write an example with GdipBitmapGetPixel from gdiplus.dll if you need it to verify this additionally. For non-transparent white it will return -1 instead of asked (and proper) 4294967295 (0xFFFFFFFF).

Special concatenation operator with new Static is missing. This shows the problem:

For $i = 0 To 100
	ConsoleWrite(StringLen(_String()) & @CRLF)
Next



Func _String()

	Local Static $sString = "Variable That Would Exceed Script Line Limit If It's All Here"

	$sString &= "The Rest Of The Variable" ; <- This adds over and over

	Return $sString

EndFunc
