Fun-sinfo

Change-fun-sinfo

Modifying constructor for fun-sinfo structures.

Syntax

(change-fun-sinfo x 
                  [:inputs <inputs>] 
                  [:output <output>] 
                  [:definedp <definedp>])

This is an often useful alternative to make-fun-sinfo.

We construct a new fun-sinfo 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.

                           (:output . fun-sinfo->output)
                           (:definedp . fun-sinfo->definedp))
