| <h2>Description</h2> | |
| <p> | |
| 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>. | |
| </p> | |
| <p> | |
| <code class="function">eglWaitGL</code> is ignored if there is no | |
| current EGL rendering context for OpenGL ES. | |
| </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. For backwards compatibility, | |
| <code class="function">eglWaitGL</code> continues to be supported and | |
| is equivalent to the series of commands | |
| </p> | |
| <pre class="programlisting"> | |
| EGLenum api = <code class="function">eglQueryAPI</code>(); | |
| <code class="function">eglBindAPI</code>(<code class="constant">EGL_OPENGL_ES_API</code>); | |
| <code class="function">eglWaitClient</code>(); | |
| <code class="function">eglBindAPI</code>(api); | |
| </pre> | |
| </div> | |
| <div class="refsect1" id="errors"> | |
| <h2>Errors</h2> | |
| <p> | |
| <code class="constant">EGL_FALSE</code> is returned if | |
| <code class="function">eglWaitGL</code> fails, | |
| <code class="constant">EGL_TRUE</code> otherwise. | |
| </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. | |
