        <h2>Description</h2>
        <p>
            This extension allows creating OpenCL event objects linked to EGL fence sync objects, 
            potentially improving efficiency of sharing images and buffers between the two APIs. The 
            companion EGL_KHR_cl_event extension provides the complementary functionality of 
            creating an EGL sync object from an OpenCL event object. 
        </p>
        <p>
            If this extension is supported by an implementation, 
            the string <code class="function">cl_khr_egl_event</code> will be present 
            in the <code class="constant">CL_PLATFORM_EXTENSIONS</code> 
            string described in table 4.1 
            (see <a class="citerefentry" href="clGetPlatformInfo.html"><span class="citerefentry"><span class="refentrytitle">clGetPlatformInfo</span></span></a>) 
            or <code class="constant">CL_DEVICE_EXTENSIONS</code> string described in table 4.3 (see
            <a class="citerefentry" href="clGetDeviceInfo.html"><span class="citerefentry"><span class="refentrytitle">clGetDeviceInfo</span></span></a>).
        </p>
        <p>
          If the <code class="function">cl_khr_egl_event</code> extension is supported, then
          the following function is enabled:
        </p>
        <div class="itemizedlist">
          <ul class="itemizedlist" style="list-style-type: disc; ">
