I believe that the order in which readdir() returns entries is *BY
DEFINITION* the order of the filesystem. If you want alphabetical
order or something else, sort it yourself.

It isn't.

Many programs, like "ls" sort the file names for display purposes.
If you want a particular order (e.g. by name or file time or size),
sort it yourself. "ls -f" gives you unsorted output if your ls has
that option.
