Vl-description->origname

Get the name from most descriptions -- original version, i.e. not modified by unparameterization, in the cases of modules and interfaces.

Signature

(vl-description->origname x) → name

Arguments

x — Guard (vl-description-p x).

Returns

name — Type (maybe-stringp name).
