| <h2>Description</h2> |
| <p> |
| <code class="function">eglBindAPI</code> defines the current |
| rendering API for EGL in the thread it is called from. The |
| current rendering API is one of the client rendering APIs |
| supported by the EGL implementation, and affects the |
| behavior of other EGL commands including |
| <code class="function">eglCreateContext</code>, |
| <code class="function">eglGetCurrentContext</code>, |
| <code class="function">eglGetCurrentDisplay</code>, |
| <code class="function">eglGetCurrentSurface</code>, |
| <code class="function">eglMakeCurrent</code>, |
| <code class="function">eglWaitClient</code>, and |
| <code class="function">eglWaitNative</code>. |
| </p> |
| <p> |
| If <em class="parameter"><code>api</code></em> is |
| <code class="constant">EGL_OPENGL_API</code>, the current rendering |
| API is set to the OpenGL API. |
| </p> |
| <p> |
| If <em class="parameter"><code>api</code></em> is |
| <code class="constant">EGL_OPENGL_ES_API</code>, the current |
| rendering API is set to the OpenGL ES API. |
| </p> |
| <p> |
| If <em class="parameter"><code>api</code></em> is |
| <code class="constant">EGL_OPENVG_API</code>, the current rendering |
| API is set to the OpenVG API. |
| </p> |
| <p> |
| If an error occurs, the current rendering API is unchanged. |
| </p> |
| </div> |
| <div class="refsect1"> |
| <a id="notes"></a> |
| <h2>Notes</h2> |
| <p> |
| <code class="function">eglBindAPI</code> and the corresponding |
| <code class="constant">EGL_OPENGL_ES_API</code> and |
| <code class="constant">EGL_OPENVG_API</code> |
| <em class="parameter"><code>api</code></em> parameters are supported only if |
| the EGL version is 1.2 or greater. The |
| <code class="constant">EGL_OPENGL_API</code> parameter is supported |
| only if the EGL version is 1.4 or greater. |
| </p> |
| <p> |
| The initial value of the current rendering API is |
| <code class="constant">EGL_OPENGL_ES_API</code> unless OpenGL ES is |
| not supported by an implementation, in which case the |
| initial value is <code class="constant">EGL_NONE</code> (however, |
| <code class="constant">EGL_NONE</code> is not a valid |
| <em class="parameter"><code>api</code></em> parameter to |
| <code class="function">eglBindAPI</code>). |
| </p> |
| <p> |
| The current rendering API can be queried by calling |
| <code class="function">eglQueryAPI</code>. |
| </p> |
| </div> |
| <div class="refsect1"> |
| <a id="errors"></a> |
| <h2>Errors</h2> |
| <p> |
| <code class="constant">EGL_FALSE</code> is returned on failure. |
| </p> |
| <p> |
| <code class="constant">EGL_BAD_PARAMETER</code> is generated if |
| <em class="parameter"><code>api</code></em> is not one of the accepted |
| tokens, or if the specified client API is not supported by |
| the EGL implementation. |
