I saw that "Change add to a static inline function. 
This is usually the right solution if only one translation
unit needs to use the function. static inline functions are
always resolved within the translation unit, so you won't have
to add a non-inline definition of the function elsewhere in your program."

So, why not just change it to "static inline" to resolve this?

Thanks,
