Change-mach-o-header

Modifying constructor for mach-o-header structures.

Syntax

(change-mach-o-header x 
                      [:magic <magic>] 
                      [:cputype <cputype>] 
                      [:cpusubtype <cpusubtype>] 
                      [:filetype <filetype>] 
                      [:ncmds <ncmds>] 
                      [:sizeofcmds <sizeofcmds>] 
                      [:flags <flags>] 
                      [:reserved <reserved>]) 

This is an often useful alternative to make-mach-o-header.

We construct a new mach-o-header 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-mach-o-header

(defmacro change-mach-o-header (x &rest args)
  (std::change-aggregate 'mach-o-header
                         x args
                         '((:magic . mach-o-header->magic)
                           (:cputype . mach-o-header->cputype)
                           (:cpusubtype . mach-o-header->cpusubtype)
                           (:filetype . mach-o-header->filetype)
                           (:ncmds . mach-o-header->ncmds)
                           (:sizeofcmds . mach-o-header->sizeofcmds)
                           (:flags . mach-o-header->flags)
                           (:reserved . mach-o-header->reserved))
                         'change-mach-o-header
                         'nil))
