<h2>Description</h2>
<p>
<code class="function">eglInitialize</code> initialized the EGL display
connection obtained with
<a class="citerefentry" href="eglGetDisplay.xhtml"><span class="citerefentry"><span class="refentrytitle">eglGetDisplay</span></span></a>.
Initializing an already initialized EGL display connection has no
effect besides returning the version numbers.
</p>
<p>
<em class="parameter"><code>major</code></em> and <em class="parameter"><code>minor</code></em>
do not return values if they are specified as <code class="constant">NULL</code>.
</p>
<p>
Use <a class="citerefentry" href="eglTerminate.xhtml"><span class="citerefentry"><span class="refentrytitle">eglTerminate</span></span></a>
to release resources associated with an EGL display connection.
</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">EGL_FALSE</code> is returned if
<code class="function">eglInitialize</code> fails,
<code class="constant">EGL_TRUE</code> otherwise.
<em class="parameter"><code>major</code></em> and <em class="parameter"><code>minor</code></em> are not
modified when <code class="constant">EGL_FALSE</code> is returned.
</p>
<p>
<code class="constant">EGL_BAD_DISPLAY</code> is generated if
<em class="parameter"><code>display</code></em> is not an EGL display connection.
</p>
<p>
<code class="constant">EGL_NOT_INITIALIZED</code> is generated if
<em class="parameter"><code>display</code></em> cannot be initialized.
