(The macros one is a lovely example of how an API may be the same but the ABI quite different. ncurses 6 has a lot of this going on vs. ncurses 5, because the public curses API has quite a few things that are implemented as macros; the ncurses 6 documentation specifically warns that the API is as close as possible to that of ncurses 5, but the ABI quite incompatible.)</div><div class="gmail_extra"><br></div><div class="gmail_extra">Very old versions of KDE also used macros this way, and they learned the hard way about this API/ABI compatibility break.<br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div>brandon s allbery kf8nh sine nomine associates</div><div><a href="mailto:allbery.b@gmail.com" target="_blank">allbery.b@gmail.com</a> <a href="mailto:ballbery@sinenomine.net" target="_blank">ballbery@sinenomine.net</a></div><div>unix, openafs, kerberos, infrastructure, xmonad <a href="http://sinenomine.net" target="_blank">http://sinenomine.net</a></div></div></div>
