    Change-byte-value

    Modifying constructor for byte-value structures.

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

    This is an often useful alternative to make-byte-value.

    We construct a new byte-value 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.

    Macro: change-byte-value

    (defmacro change-byte-value (x &rest args)
      (std::change-aggregate 'byte-value
                             x args '((:int . byte-value->int))
                             'change-byte-value
                             'nil))
