Hi,

I would like my C code to throw an exception that I can then catch from the
script that invoked it. Ideally the exception I throw would be subclassed
from "Error" (so I'll inherit the toString() method and stack property; the
message property would be overloaded).

So I'd need to create a prototype object with the Error class defined in
jsexn.c (ExceptionClass), and then I can use that in a call to JS_InitClass.
But ExceptionClass is a static structure. So I don't see how to do this
without modifying the SpiderMonkey source (which I don't want to do for
licensing reasons).

Is there another (intended) way to do this?

thanks,
Jeroen
