Pointer variables

[aommaster]

Hi guys

Does Autoit support pointer variables, ie. variables that contain the memory location of other variables so that they can be used to pass arrays down to functions?

I looked at the PTR function, but that doesn't seem to be what I am looking for.

Thanks guys

Hi

Sure it does.

Look at DllStructCreate, DllStructSet/GetData and DllStructGetPtr

Directly something like PTR() no but look at DllStructCreate(), DllStructGetPtr()

Awesome. Thanks everyone!

Hi!

In autoit you cannot access variables by their addresses, it's still easy to pass arrays to functions.

Example:

Local $arr[10 ^ 6]
For $i = 0 To UBound($arr) - 1
    $arr[$i] = $i
Next

$timer=TimerInit()
SlowArray($arr)
ConsoleWrite("Calling without ByRef took: "&@TAB&TimerDiff($timer)&" ms."&@CRLF)

$timer=TimerInit()
FastArray($arr)
ConsoleWrite("Calling with ByRef took: "&@TAB&TimerDiff($timer)&" ms."&@CRLF)

Func FastArray(ByRef $arr)
    
    
EndFunc  ;==>FastArray

Func SlowArray($ArrCopy)
    
EndFunc  ;==>SlowArray

ByRef in this case could be looked at as a pointer.
