Am I misunderstanding the function?
You must think of the permissions as a bitset (actually, it IS a bitset).
If a file is encrypted, 0000000000 means: nothing is allowed, whereas
1001001011 means: some things are allowed (but not everything).
If a file isn't encrypted, there's no need for a bitset. Its value is 0 (or
0000000000 if you prefer).
So if you ask a non-encrypted file "Is the 'printing allowed' bit set?" you
get the response: "No, it isn't set!"
Which is a correct answer, because the bit isn't set. Hope this answers your
question.
