Subj : argv argument to JS_InstanceOf To : netscape.public.mozilla.jseng From : Braden McDaniel Date : Mon Aug 11 2003 12:54 am The SpiderMonkey API docs for JS_InstanceOf include If you pass a non-null argument vector, argv, to JS_InstanceOf, and obj is not an instance of clasp, this function may report a class mismatch before returning. To do so, JS_InstanceOf tests whether or not there is a function name associated with the argument vector, and if there is, reports the name in an error message using the JS_ReportError function. I'm really not sure exactly what that second sentence means. Could someone provide a brief example of how this would be used? -- Braden McDaniel e-mail: Jabber: .
