No, they are _descriptions_. The descriptor is the number you get back
from doing something like an open(). The description is the thing that
the descriptor points to. This is the terminology that POSIX uses, and
is what was recommended by the glibc and manpages maintainers.

The glibc doc patches lay this out in detail. I'm not terribly thrilled
with the name either, fwiw, but it is better than file-private.
