Spidermonkey embedding: How can I set Class Properties?

[Blake McBride]

Greetings,

I am embedding Spidermonkey in a C app. and I'm having trouble setting
class (not instance) property values. For example, I am setting up
the class as follows:
static JSBool constructor(JSC ontext *cx, JSObject *obj, uintN argc, jsval
*argv, jsval *rval)
{
printf("constru ctor argc = %d\n", argc);
*rval = OBJECT_TO_JSVAL (obj);
return JS_TRUE;
}

main()
{
....
static JSClass my_class = {
"MyClass", JSCLASS_HAS_PRI VATE,
JS_PropertyStub ,JS_PropertyStu b,JS_PropertySt ub,JS_PropertyS tub,
JS_EnumerateStu b,JS_ResolveStu b,JS_ConvertStu b,JS_FinalizeSt ub
};
static JSPropertySpec class_props[] = {
{"Prop1", 0, JSPROP_ENUMERAT E},
{0}
};
JSObject *proto;

proto = JS_InitClass(cx , JS_GetGlobalObj ect(cx), 0, &my_class,
constructor, 1, NULL, NULL, class_props, NULL);

The above code correctly (verified through a JavaScript program)
creates a new class with the Prop1 class property.

The following code correctly adds an _instance_ property:

jsval val = INT_TO_JSVAL(42 );
JS_SetProperty( cx, proto, "MyProp2", &val);

After three days I still can't figure out how to set the value of the class
property,
or, for that matter, create a new class property with a particular value. I
am looking to
do something like this:
jsval val = INT_TO_JSVAL(88 );
JS_SetProperty( cx, ???, "Prop1", &val);

Any help would really be appreciated.

Lost maybe, but this sort of has something to do with javascript. But
this group is more about the use of the language then its
implementations . A good group to ask questions about the Spidermonkey
and/or Rhino implementations is - netscape.public .mozilla.jseng -, as
there they may get the attention of the authors of those
implementations .

Spidermonkey is Mozilla's JavaScript engine. I'm trying to embed it in a C
application.
