Vl-unparam-class

Compute the final parameter values for a static class scope invocation

Signature

(vl-unparam-class x elabindex ledger warnings &key (config 'config)) 
  → 
(mv successp warnings new-classname instkey new-elabindex ledger)

Arguments

x — Classname and parameters needed for some function call occurrence.
    Guard (classname/params-p x).

elabindex — at the instanting context.

ledger — Guard (vl-unparam-ledger-p ledger).

warnings — Warnings accumulator for the submodule.
    Guard (vl-warninglist-p warnings).

config — Guard (vl-simpconfig-p config).

Returns

successp — Type (booleanp successp).

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

new-classname — Type (stringp new-classname).

instkey — An instkey for the parameterized class, if needed.
    Type (implies successp (vl-unparam-instkey-p instkey)).

ledger — Type (vl-unparam-ledger-p ledger).
