Access to C++ exceptions from GNAT ?

Access to C++ exceptions from GNAT ?

[@ 1996-04-05 0:00 UTC (permalink / raw)]

Hello,

I know that there is a paper on how to access "normal" C++
classes from Ada.
My question is, how do get access to C++ exceptions ?
I know that there is quite a diffrence between Ada and C++ exceptions,
but I am asking because I would like to evaluate if it is possible
to write an Ada binding to some of the freely available OS/2 
class libraries.

Currently there is no way to interoperate with exceptions between C++
and GNAT. This will change in the future when we integrate the exception
handling in GNAT and g++.

You can always write wrappers that translate the exceptions into flags,
and then pick up the flags on the Ada side and reraise the exceptions.
