Char-array

Change-char-array

Modifying constructor for char-array structures.

Syntax

(change-char-array x 
                   [:components <components>])

This is an often useful alternative to make-char-array.

We construct a new char-array 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
