The managed struct is of course a value type. Try passing your struct reference like so (MonoObject *)&x I think that a struct returned by a method is a MonoObject * that you can access using normal field and property accessors.
If curious, you could glance at the following - it’s Obj-C not C++ but it might help. https://github.com/ThesaurusSoftware/Dubrovnik/blob/master/Framework/XCode/Utility/DBInvoke.m https://github.com/ThesaurusSoftware/Dubrovnik/blob/master/Framework/XCode/Dubrovnik%20Unit%20Tests/DBUReferenceObject.m I agree that Mono is great but the embedded API is quite opaque and the headers and overall level of documentation is minimalist to say the least. It does make for quite a steep learning curve but the community is genuinely helpful. _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
