There is no such function. You can either use
S.R.Assembly.GetExportedTypes ()´via mono_runtime_invoke (),
or something like this:


/*
  * Enumerates the classes of the specified assembly.
  * Similar to mono_class_get_{methods|fields|events|...}.
  */
static
MonoClass*
mono_assembly_get_classes (MonoAssembly *assembly, gpointer *iter)
{
	MonoImage *image;
	int num_types;
	gssize *index;

	if (!iter)
		return NULL;

	index = (gssize *) iter;

	/* skip the <Module> */
	if (!*index)
		*index = 1;

	image = mono_assembly_get_image (assembly);
	num_types = mono_image_get_table_rows (image, MONO_TABLE_TYPEDEF);

	if (*index < num_types) {
		(*index)++;
		return mono_class_get (image, *index | MONO_TOKEN_TYPE_DEF);
	} else {
		*index = 0;
		return NULL;
	}
}

Note that function is using old-style GLib types, so you'll probably
have to replace gpointer, gssize with... something else.
