Sorry, was thinking of different functions (not the container related ones).

Unfortunately, we don't have a generic API for these, but since we 
export a single API on all platforms, either all platforms have to 
implement these functions, or none of them do. There's simply no way to 
avoid implementing stubs for these functions, short of coming up with a 
generic API that would replace these. Given that this API is heavily 
Linux specific, i don't see that happening.
