Win* functions to set @error or @extended flag in case of fail / timeout

[anonymous]

Now Win* functions have only one return value:

Success: a handle to the window.
Failure: 0 if the window is not found.

Success: a string containing the complete window title.
Failure: "" if the window is not found.

and so on. I think it would produce more readable, simpler code if
Win* functions also can set @error or @extended flag in case of fail or timeout

Maybe same could be applied to other functions with only one return value

How would that make the code more readable or simpler? It already tells you it's failed by not returning 1, I don't see any gain to be made by adding an error code that has no meaning.

It's just as readable and, frankly, simpler to write this:

If WinActive("Notepad") Then

As it is to write this

WinActive("Notepad")
If @error Then
;~ or
If @error <> 0 Then
