+A single buffer is used for all of the paths of all of the files in the
+file hierarchy.
+Therefore, the
+.Fa fts_path
+and
+.Fa fts_accpath
+fields are guaranteed to be
+.Dv NULL Ns -terminated
+.Em only
+for the file most recently returned by
+.Fn fts_read .
+To use these fields to reference any files represented by other
+.Fa FTSENT
+structures will require that the path buffer be modified using the
+information contained in that
+.Fa FTSENT
+structure's
+.Fa fts_pathlen
+field.
+Any such modifications should be undone before further calls to
+.Fn fts_read
+are attempted.
+The
+.Fa fts_name
+field is always
+.Dv NULL Ns -terminated.
