Maybe you should use -1? Since code is unsigned in the spec, that should never
conflict with a real code. What do you think?

Yes, in the same reason, I defined the equivalent code as -1 in the WebKit API.
As you said in the following comments, -1 must be better if I can change
argument type from unsigned short.
