I also thought that these functions and defines were internal,
but they aren't. Since the Mono API is quite stable, you don't need
to worry.

Anyway, here is the interator I'm using.

/*
  * Iterator routine for retrieving the classes of an assembly.
  * Similar to mono_class_get_{methods|fields|events|...}.

MonoClass*
mono_image_get_classes (MonoImage *image, gpointer *iter)
{
	int num_types;
	int *index;

	if (!iter)
		return NULL;

	index = (int *) iter;

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

	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;
	}
}
