Vl-namefactory-indexed-name

(vl-namefactory-indexed-name prefix factory) constructs a fresh name that looks like prefix_n for some natural number n, and returns (mv fresh-name factory-prime).

Signature

(vl-namefactory-indexed-name prefix factory) 
  → 
(mv fresh-name new-factory)

Arguments

prefix — Guard (stringp prefix).

factory — Guard (vl-namefactory-p factory).

Returns

fresh-name — Type (stringp fresh-name).

new-factory — Type (vl-namefactory-p new-factory).
