No, I don't.  Anyone can read what elements are within a struct version of
FILE.  It's declared within stdio.h.  With a FILE pointer, anyone can  
access
those elements too.  They'll be specific to the specific implementation.

Does non-necessity of use constitute hiding?  Nothing is hidden.
It's all accessible and useable, even if it's not that useful.
