FileOpen() and similar functions should set @error to non-zero on failure

[anonymous]

I wonder why some File* and all Dir* functions don't set @error to non-zero on failure? Imho this is not a bug, but breaks uniformity somehow…
For example, could FileOpen() set such @error flags as these?
1 = file not found
2 = access denied
3 = $FO_APPEND/$FO_OVERWRITE set while file is read-only
… etc
Thank you for attention!

You are assuming that AutoIt3 knows all these conditions, in stead of just trying to open the file and returning a @error=-1 in case it fails.

Just make your own UDF _FileOpen() that does these extra checks and balances as that really should be pretty simply to code when required. ;)

It is true that, from the beginning, a lot of AutoIt builtin function was not using the @error.
It would be a hard work to introduce @error in these functions.
But perhaps you can easy use _WinAPI_GetLasterror() in a udf as mention by Jos,
