Hi all,
I am trying to pass a reference to a managed object to unmanaged code
where I would like to handle it like a MonoObject, so I could use the
momo_embed API to call methods of the managed object from unmanaged code.
What I have in mind is some kind of C#/C++ peership where each C#
instance of a certain Object has a C++ peer object and the other way round.
I tried something like this:
C#:
...
[DllImport("Simkernel",EntryPoint="SetCsharpPeer")]
public static extern void MyClass_SetCsharpPeer(
HandleRef jarg1,
[MarshalAs(UnmanagedType.Struct)]HandleRef jarg2
)
...
MyClass::SetCsharpPeer(MonoObject* object)
{
csharpPeer = Object;
...
}
after calling SetCsharpPeer I try something like;
...
MonoClass* klass = mono_object_get_class(csharpPeer);
MonoMethod *m = NULL;
gpointer iter = NULL;
while((m = mono_class_get_methods (klass, &iter))) {
...
}
...
which results in SEGFAULT when calling mono_class_get_methods.
I did not find anythig about how a csharp object should be marshalled to
access it as a MonoObject in unmanaged code. So UnmanagedType.Struct was
the best guess but since it does not seem to work i obviously have guessed
wrong.
Is there any way to do what I intend? If so, could anyone please point out how
to do this or tell me where to learn about it?
Thanks for your help and best regards,
Andreas
