Yes.. My alloc/free looks something like this (ruby-1.8.0)


void Free(Klass *p) {
	delete p;
}

VALUE Alloc(VALUE self) {
	Klass* p = new Klass();
	return Data_Wrap_Struct(self, 0, Free, p);
}     

void KlassInit() { 
	VALUE h = rb_define_class("Klass", rb_cObject);
	rb_define_alloc_func(h, Alloc);
}
