directory <-roots: -> chain

The method directory<-roots gathers the roots of the filesystem. On Unix, there is only one root, so a chain holding only’/’is returned. On windows, it returns the path-names of all defined logical drives. This call is used by library(find_file) to show all defined drives after an up from a drive-root.

The content of the directory object itself is not examined. For example (Windows):

?- get(directory('.'), roots, Roots),
   chain_list(Roots, List).

List = ['a:/', 'c:/', 'd:/', 'e:/', 's:/']
