Change-int

Modifying constructor for int structures.

Syntax

(change-int x 
            [:size <size>] 
            [:value <value>])

This is an often useful alternative to make-int.

We construct a new int 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.

                         '((:size . int->size)
                           (:value . int->value))
                         'change-int
                         'nil))
