Segment-driver

Change-segment-driver

Modifying constructor for segment-driver structures.

Syntax

(change-segment-driver x 
                       [:lsb <lsb>] 
                       [:width <width>] 
                       [:value <value>] 
                       [:strength <strength>])

This is an often useful alternative to make-segment-driver.

We construct a new segment-driver 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 defprod.

Macro: change-segment-driver

(defmacro change-segment-driver (x &rest args)

                         '((:lsb . segment-driver->lsb)
                           (:width . segment-driver->width)
                           (:value . segment-driver->value)
                           (:strength . segment-driver->strength))
                         'change-segment-driver
