<h1 style="text-align:center"> Khronos EGL&trade; Registry </h1>

<p> The EGL registry contains specifications of the core API; specifications
    of Khronos- and vendor-approved EGL extensions; header files
    corresponding to the specifications; an enumerant and function registry;
    and other related documentation. </p>

<h6> EGL Core API Specification and Headers </h6>

<p> The current version of EGL is EGL 1.5. </p>

<ul>

<li> <a href="api/EGL/egl.h"> &lt;EGL/egl.h&gt; </a> for EGL 1.5. </li>
<li> <a href="api/EGL/eglext.h"> &lt;EGL/eglext.h&gt; </a> for EGL 1.5. </li>

<li> <a href="api/KHR/khrplatform.h"> &lt;KHR/khrplatform.h&gt; </a>
     (required by the current EGL and OpenGL ES headers). </li>
</ul>

<h6> Man Pages, Technical Notes and White Papers </h6>

<h6> Older Specifications </h6>

<p> Older versions of the EGL Specification provided for reference. </p>

<ul>
<li> <a href="specs/eglspec.1.4.pdf"> EGL 1.4 Specification </a> and
     <a href="specs/eglspec.1.4.withchanges.pdf"> Specification with changes

<h6> EGL XML API Registry </h6>

<p> The database from which EGL enumerant ranges are reserved and the
    <tt>EGL/egl.h</tt> and <tt>EGL/eglext.h</tt> headers are built is called
    <a href="api/egl.xml"> egl.xml </a>. It uses an XML schema and
    processing scripts shared with the OpenGL and OpenGL ES registries. If
    you need to generate modified headers or modify egl.xml, clone the <a
    href="https://github.com/KhronosGroup/EGL-Registry"> EGL-Registry </a>
    git repository and see the <a href="README.md"> README.md </a>
    file to get started. </p>
