| <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. |
