<h2>Description</h2>
<p>
All rendering calls for the currently bound context, for the
current rendering API, made prior to
<code class="function">eglWaitClient</code> are guaranteed to be
executed before native rendering calls made after
<code class="function">eglWaitClient</code>. The same result can be
achieved using client API-specific commands such as
<a class="citerefentry" href="glFinish.xhtml"><span class="citerefentry"><span class="refentrytitle">glFinish</span></span></a>
or
<a class="citerefentry" href="vgFinish.xhtml"><span class="citerefentry"><span class="refentrytitle">vgFinish</span></span></a>.
</p>
<p>
<code class="function">eglWaitClient</code> is ignored if there is no
current EGL rendering context for the current rendering API.
</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p>
<code class="constant">EGL_FALSE</code> is returned if
<code class="function">eglWaitClient</code> fails,
<code class="constant">EGL_TRUE</code> otherwise.
</p>
<p>
If there is no current context for the current rendering
API, the function has no effect but still returns
<code class="constant">EGL_TRUE</code>.
</p>
<p>
<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window or pixmap, and that window or pixmap is no longer
valid.
</p>
</div>
<div class="refsect1" id="notes">
<h2>Notes</h2>
<p>
<code class="function">eglWaitClient</code> is supported only if the
EGL version is 1.2 or greater.
</p>
<p>
<code class="function">eglWaitClient</code> is a generalized version
of <code class="function">eglWaitGL</code>, supporting multiple
client APIs.
