Does engine shutdown or die on AV in your case?
I'm talking About fb 2.5. When i test with it, an AV raises and the engine
shutdown abnormally.
The question is If an error in the engine that causes fb terminate abnormally
can corrupt database or the engine closes all connections and

I would prefer to leave this task to the author of the API. Just to make him

Could you send to me your Delphi wrapper for the API ?

UDF installation is restricted to administrators, for the same reason.
The UDF directory is restricted, too.
An UDF is simply a library that runs as native code in the same address
space as the FB process. Big problem if it misbehaves. Maybe the problem
could be isolated better by running in
Hello all, i wrote time ago this item in the firebird-support list, but
vlad suggest to write it in the devel list.
The question is that doing some test, i use one udf function in one dll
that raises an exception that the function did not catch.
When that exception raised, the firebird engine

How??? How the engine catch an alien exception? Could you show the method

I don,t know how and if is possible, There must be a point in firebird
where a call to an udf in a dll is executed, and i don't know if is
possible to catch an exception that is raised in
The engine does what is possible and tries to catch the 'alien exception'.
You must do your part and write a correct UDF, testing them before in
non-production environment.

But it will make OS to close your application harshly. Exactly as it is done

Because every programmer know that exceptions can hardly pass boundaries of
DLL. Now it
is time for you to learn it too.

Thank you very much for the lesson, but you say can hardly not can't.
Sorry for the post and for waste your valuable time with me.

Thank you again for the lesson, i did never link the positions of thr stars

First off to say that I fully agree that a UDF must not let
exceptions escape. I have no issue with that.
Claudio says in the v2.1.4 release notes: Since UDFs have no
formal mechanism to signal errors, the returned value would
have to be used as an indicator.
I was wondering if anyone had had
