Vl-name-is-interface-or-type

Looks up x in the scopestack to see if it looks like an interface or type name. Warns if the result was ambiguous.

Signature

(vl-name-is-interface-or-type x ss) 
  → 
(mv warnings looks-like-interface looks-like-type)

Arguments

x — Guard (stringp x).

ss — Guard (vl-scopestack-p ss).

Returns

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