iuplua51.exe?
No. Reuse the executable without recompiling it from source code.

Called inside IUP, but they are exported also in the DLL.

automatically and shows a dialog with the error info. Is that true?
Yes. If you provoke an error you will see that dialog.
So, your function can fully replace that dialog.
