| <h2>Description</h2> | |
| <p> | |
| <code class="function">eglGetDisplay</code> obtains the | |
| <abbr class="acronym">EGL</abbr> display connection for the native | |
| display <em class="parameter"><code>native_display</code></em>. | |
| </p> | |
| <p> | |
| The behavior of <code class="function">eglGetDisplay</code> is similar to | |
| that of | |
| <a class="citerefentry" href="eglGetPlatformDisplay.xhtml"><span class="citerefentry"><span class="refentrytitle">eglGetPlatformDisplay</span></span></a>, | |
| but is specified in terms of implementation-specific behavior | |
| rather than platform-specific extensions. As for | |
| <a class="citerefentry" href="eglGetPlatformDisplay.xhtml"><span class="citerefentry"><span class="refentrytitle">eglGetPlatformDisplay</span></span></a>, | |
| EGL considers the returned <span class="type">EGLDisplay</span> as belonging | |
| to the same platform as <em class="parameter"><code>display_id</code></em>. | |
| However, the set of platforms to which | |
| <em class="parameter"><code>display_id</code></em> is permitted to belong, as | |
| well as the actual type of <em class="parameter"><code>display_id</code></em>, | |
| are implementation-specific. If | |
| <em class="parameter"><code>display_id</code></em> is | |
| <code class="constant">EGL_DEFAULT_DISPLAY</code>, a <em class="firstterm">default | |
| display</em> is returned. Multiple calls made to | |
| <code class="function">eglGetDisplay</code> with the same | |
| <em class="parameter"><code>display_id</code></em> will return the same | |
| <span class="type">EGLDisplay</span> handle. | |
| </p> | |
| <p> | |
| If <em class="parameter"><code>display_id</code></em> is | |
| <code class="constant">EGL_DEFAULT_DISPLAY</code>, a default display connection is returned. | |
| </p> | |
| <p> | |
| If no display connection matching <em class="parameter"><code>native_display</code></em> is | |
| available, <code class="constant">EGL_NO_DISPLAY</code> is returned. No | |
| error is generated. | |
| </p> | |
| <p> | |
| Use <a class="citerefentry" href="eglInitialize.xhtml"><span class="citerefentry"><span class="refentrytitle">eglInitialize</span></span></a> | |
| to initialize the display connection. | |
