Vl-namemangle-vardecls

Safely try to give these vardecls new names of the form prefix_{current-name}.

Signature

(vl-namemangle-vardecls prefix vardecls nf) 
  → 
(mv new-vars new-nf)

Arguments

prefix — Guard (stringp prefix).

vardecls — Guard (vl-vardecllist-p vardecls).

nf — Guard (vl-namefactory-p nf).

Returns

new-vars — Type (vl-vardecllist-p new-vars).

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

You'll generally want to do something like:

(pairlis$ (vl-vardecllist->names old-vardecls)
          (vl-vardecllist->names renamed-vardecls))

And then use this as a substitution.
