<para>
All rendering calls for the currently bound context, for the
current rendering API, made prior to
<function>eglWaitClient</function> are guaranteed to be
executed before native rendering calls made after
<function>eglWaitClient</function>. The same result can be
achieved using client API-specific commands such as
<citerefentry><refentrytitle>glFinish</refentrytitle></citerefentry>
or
<citerefentry><refentrytitle>vgFinish</refentrytitle></citerefentry>.
</para>
<para>
<function>eglWaitClient</function> is ignored if there is no
current EGL rendering context for the current rendering API.
</para>
</refsect1>
<refsect1 id="errors"><title>Errors</title>
<para>
<constant>EGL_FALSE</constant> is returned if
<function>eglWaitClient</function> fails,
<constant>EGL_TRUE</constant> otherwise.
</para>
<para>
If there is no current context for the current rendering
API, the function has no effect but still returns
<constant>EGL_TRUE</constant>.
</para>
<para>
<constant>EGL_BAD_CURRENT_SURFACE</constant> 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window or pixmap, and that window or pixmap is no longer
valid.
</para>

<refsect1 id="notes"><title>Notes</title>
<para>
<function>eglWaitClient</function> is supported only if the
EGL version is 1.2 or greater.
</para>
<para>
<function>eglWaitClient</function> is a generalized version
of <function>eglWaitGL</function>, supporting multiple
client APIs.
