I don't follow. One thing is to provide an interface which totally abstracts
from low-level details. Another is to provide a function which holds different
results depending on the operating system. I'm fine to have different functions
available for different purposes on different platforms, I'm not fine with
having a single function which does different things. Do you have any other
example?
