Signature

(vl-scopestack-find-definition/ss name ss) 
  → 
(mv definition definition-ss)

Arguments

name — Guard (stringp name).

ss — Guard (vl-scopestack-p ss).

Returns

definition — The declaration, if found.
    Type (iff (vl-scopedef-p definition) definition).

definition-ss — The scopestack showing the context of the declaration.
    Type (vl-scopestack-p definition-ss).
