Cconst

Change-cconst

Modifying constructor for cconst structures.

Syntax

(change-cconst x 
               [:prefix? <prefix?>] 
               [:cchars <cchars>])

This is an often useful alternative to make-cconst.

We construct a new cconst 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

This is an ordinary change- macro introduced by fty::defprod.
