Vl-dependent-elements-direct

Gathers the names of all design elements that directly depend on particular descriptions.

Signature

(vl-dependent-elements-direct subs design) → superiors

Arguments

subs — Names of the sub design elements we're interested in.
    Guard (string-listp subs).

design — The design.
    Guard (vl-design-p design).

Returns

superiors — Names of the superior design elements that directly depend on these sub elements.
    Type (and (string-listp superiors) (setp superiors)).
