<h4 class="subsection">8.1.2 Traditional GNU Objective-C Runtime API</h4>
|
|
|
|
<p>The GNU Objective-C runtime used to provide a different API, which we
|
|
call the “traditional” GNU Objective-C runtime API. Functions
|
|
belonging to this API are easy to recognize because they use a
|
|
different naming convention, such as <code>class_get_super_class()</code>
|
|
(traditional API) instead of <code>class_getSuperclass()</code> (modern
|
|
API). Software using this API includes the file
|
|
<samp><span class="file">objc/objc-api.h</span></samp> where it is declared.
|
|
|
|
<p>Starting with GCC 4.7.0, the traditional GNU runtime API is no longer
|
|
available.
