Var-info

Change-var-info

Modifying constructor for var-info structures.

Syntax

(change-var-info x 
                 [:type <type>] 
                 [:linkage <linkage>])

This is an often useful alternative to make-var-info.

We construct a new var-info structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition
