Subj : (Spidermonkey) Converting a property name to a tinyId

I have a pressing need to map a string which *might* be the name of
property I've defined on an object to it's numerical ID. Essentially I
need a function which returns either a failure  or the value I passed
in via the JSPropertySpec to JS_InitClass.

Essential I want:

int8 tinyid;
JSBool hasTinyId = JS_GetPropertyTinyId(ctx, obj, "foo", &tinyid);

to return true, and set tinyid to be (say) 42, assuming the
JSPropertySpec looked like

{ "foo", 42, ... flags .... },

I've looked through the jsobj.c code but am getting lost rather
easily, so could someone tell me if this is even possible? I could
maintain a seperate lookup table by hand by copying the JSPropertySpec
array I pass to JS_InitClass, but I figure that table has *got* to
exist somewhere internally.

Many thanks,
James
