Vl-slow-find-net/reg-range

Look up the range for a wire or variable declaration.

Signature

(vl-slow-find-net/reg-range name mod) 
  → 
(mv successp maybe-range)

Arguments

name — Guard (stringp name).

mod — Guard (vl-module-p mod).

Returns

successp — True when name is the name of a wire or variable.
    Type (booleanp successp).

maybe-range — The range of the wire, on success.
    Type (vl-maybe-range-p maybe-range).
