Vl-time

Change-vl-time

Modifying constructor for vl-time structures.

Syntax

(change-vl-time x 
                [:quantity <quantity>] 
                [:units <units>])

This is an often useful alternative to make-vl-time.

We construct a new vl-time 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-vl-time

                         x args
                         '((:quantity . vl-time->quantity)
                           (:units . vl-time->units))
                         'change-vl-time
                         'nil))
