And now even with exception handling ;-)


extern gpointer mono_method_get_unmanaged_thunk (MonoMethod *method);


typedef void (*VoidFunction) (MonoDelegate *, MonoException **);

static void*
gimme (MonoDelegate * obj)
{
     MonoException* ex;
     MonoMethod * method = 
mono_get_delegate_invoke(mono_object_get_class ((MonoObject*)obj));
     VoidFunction MyFunction = mono_method_get_unmanaged_thunk (method);
     MyFunction (obj, &ex);
     if (ex)
	    printf ("got an exception!\n");
}
