Thanks for that. It sounds like MonoAppDomain is what I am after.
I am trying to register for the System.AppDomain.UnhandledException event.
I use an Obj-C bridge (https://github.com/ThesaurusSoftware/Dubrovnik) to hook up managed events to static native callback functions.
In order to do this I need a MonoObject * representation of the managed object.
It looks as if the public embedded API is deficient in this case.
We do have
MONO_API MonoDomain *
mono_domain_from_appdomain (MonoAppDomain *appdomain);
but there is no function the supplies MonoDomain->domain.
I think this means that System.AppDomain is effectively off limits for the embedded API as without access to a MonoObject * we cannot query methods etc or invoke the runtime.
At a pinch I could do what I need in managed code but I will try and add the required accessor to appdomain.c and see how I get on.
