<h2>Description</h2>
<p>
<code class="function">eglCopyBuffers</code> copies the color buffer of
<em class="parameter"><code>surface</code></em> to <em class="parameter"><code>native_pixmap</code></em>.
</p>
<p>
<code class="function">eglCopyBuffers</code> performs an implicit
<a class="citerefentry" href="glFlush.html"><span class="citerefentry"><span class="refentrytitle">glFlush</span></span></a>
before it returns. Subsequent
GL commands may be issued immediately after calling
<code class="function">eglCopyBuffers</code>,
but are not executed until copying of the color buffer is completed.
</p>
</div>
<div class="refsect1">
<a id="notes"></a>
<h2>Notes</h2>
<p>
The color buffer of <em class="parameter"><code>surface</code></em> is left unchanged
after calling <code class="function">eglCopyBuffers</code>.
</p>
</div>
<div class="refsect1">
<a id="errors"></a>
<h2>Errors</h2>
<p>
<code class="constant">EGL_FALSE</code> is returned if swapping of the
surface buffers fails, <code class="constant">EGL_TRUE</code> otherwise.
</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> has not been initialized.
</p>
<p>
<code class="constant">EGL_BAD_SURFACE</code> is generated if
<em class="parameter"><code>surface</code></em> is not an EGL drawing surface.
</p>
<p>
<code class="constant">EGL_BAD_NATIVE_PIXMAP</code> is generated if
the implementation does not support native pixmaps.
</p>
<p>
<code class="constant">EGL_BAD_NATIVE_PIXMAP</code> may be generated if
<em class="parameter"><code>native_pixmap</code></em> is not a valid native pixmap.
</p>
<p>
<code class="constant">EGL_BAD_MATCH</code> is generated if
the format of <em class="parameter"><code>native_pixmap</code></em> is not compatible
with the color buffer of <em class="parameter"><code>surface</code></em>.
</p>
<p>
<code class="constant">EGL_CONTEXT_LOST</code> is generated if a power management
event has occurred. The application must destroy all contexts and
reinitialise OpenGL ES state and objects to continue rendering.
