I see no "mixed signals" here.  The first instance doesn't say it returns
the list, but rather "creates a list".  It returns the number of files in
that list.

opendir() doesn't give you the list.  It creates the list and returns
the size of that list.

To get the list itself, either iterate through using nextdir(), or use
the @DIRLIST_*[] system arrays.
