JS_GetPrivate returns a void*.  It can be used (with JS_SetPrivate) to 
store some non-spidermonkey-related data on your object.  So I'm not 
sure where JS_ObjectIsFunction comes into this.

In general, if JS_GetPrivate returned something nonzero, that means 
something was stored with JS_SetPrivate.  I'm not sure whether that 
answers the question you're trying to ask, though, because I'm not sure 
what that question is.
