hello, everyone.

I am using spidermonkey, and want to implenment such a javascript:
.......
<script>
var rec;
rec = foo();
</script>
... ...
foo() is the native C function called from javscript. 

I want foo() return a string, so I define 
JSString *foo(JSContext *cx, JSObject *obj, uintN argc, jsval *argv,
jsval *rval). and JS_DefineFunction(context, global, "foo", foo, 1,
0);

But the compiler complainted that: passing JSString * (*)(JSContext *,
JSObject *, unsigned int, jsval *, jsval *) as argument 4 of
'JS_DefineFunction(JSContext *, JSObject *, const char *, JSBool
(*)(JSContext *, JSObject *, unsigned int, jsval *, jsval *), unsigned
int, unsigned int)'.

Does this mean the functions called from javascript should be JSBool
type? and how can I get a JSString return value?

Thanks!
