dir — Directory to list.
    Guard (stringp dir).

warnings — Warnings to extend in case of file errors.
    Guard (vl-warninglist-p warnings).

Returns

cache — Type (vl-dircache-p cache).

warnings — Type (vl-warninglist-p warnings).

state — Type (state-p1 state), given (force (state-p1 state)).
