JavaScriptCoreContextpush_exception_handler

Push an exception handler in context. Whenever a JavaScript exception happens in the JSCContext, the given handler will be called. The default JSCExceptionHandler simply calls jsc_context_throw_exception() to throw the exception to the JSCContext. If you don’t want to catch the exception, but only get notified about it, call jsc_context_throw_exception() in handler like the default one does. The last exception handler pushed is the only one used by the JSCContext, use jsc_context_pop_exception_handler() to remove it and set the previous one. When handler is removed from the context, destroy_notify i called with user_data as parameter.
