  77. <h4 class="subsection">8.1.2 Traditional GNU Objective-C Runtime API</h4>

  78. 

  79. <p>The GNU Objective-C runtime used to provide a different API, which we

  80. call the &ldquo;traditional&rdquo; GNU Objective-C runtime API.  Functions

  81. belonging to this API are easy to recognize because they use a

  82. different naming convention, such as <code>class_get_super_class()</code>

  83. (traditional API) instead of <code>class_getSuperclass()</code> (modern

  84. API).  Software using this API includes the file

  85. <samp>objc/objc-api.h</samp> where it is declared.

  86. </p>

  87. <p>Starting with GCC 4.7.0, the traditional GNU runtime API is no longer

  88. available.
