All OpenGL ES rendering calls for the currently bound OpenGL
ES context made prior to <code class="function">eglWaitGL</code> are
guaranteed to be executed before native rendering calls made
after <code class="function">eglWaitGL</code>. The same result can be
achieved using
<a class="citerefentry" href="glFinish.xhtml"><span class="citerefentry"><span class="refentrytitle">glFinish</span></span></a>.
<code class="function">eglWaitGL</code> is ignored if there is no
current EGL rendering context for OpenGL ES.
<div class="refsect1" id="notes">
<code class="function">eglWaitClient</code> is supported only if the
EGL version is 1.2 or greater.
<code class="function">eglWaitClient</code> is a generalized version
of <code class="function">eglWaitGL</code>, supporting multiple
client APIs. For backwards compatibility,
<code class="function">eglWaitGL</code> continues to be supported and
is equivalent to the series of commands

<code class="constant">EGL_FALSE</code> is returned if
<code class="function">eglWaitGL</code> fails,

<code class="constant">EGL_BAD_CURRENT_SURFACE</code> is generated if
the surface associated with the current context has a native
window or pixmap, and that window or pixmap is no longer
