      General information about sharing memory objects with Direct3D 10 follows.
    </p>
        <p>
        The goal of this extension is to provide interoperability between
        OpenCL and Direct3D 10. This is designed to function analogously
        to the <a class="citerefentry" href="cl_khr_gl_sharing.html"><span class="citerefentry"><span class="refentrytitle">OpenGL
        interoperability</span></span></a> as defined in sections 9.7 and 9.8. If
        this extension is supported by an implementation, the string "cl_khr_d3d10_sharing"
        will be present in the <code class="constant">CL_PLATFORM_EXTENSIONS</code>
        (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> 
        (see <a class="citerefentry" href="clGetDeviceInfo.html"><span class="citerefentry"><span class="refentrytitle">clGetDeviceInfo</span></span></a>).
    </p>
        <p>
        As currently proposed the interfaces for this extension would be provided in
        <code class="code">cl_d3d10.h</code>.
    </p>
        <p>
        
        The OpenCL functions enabled by the <code class="function">cl_khr_d3d10_sharing</code> extension
        allow applications to use Direct3D 10 resources as OpenCL memory objects. This allows
        efficient sharing of data between OpenCL and Direct3D 10. The OpenCL API may be used
        to execute kernels that read and/or write memory objects that are also Direct3D 10
        resources. An OpenCL image object may be created from a Direct3D 10 texture resource. An
        OpenCL buffer object may be created from a Direct3D 10 buffer resource. OpenCL memory
        objects may be created from Direct3D 10 objects if and only if the OpenCL context
        has been created from a Direct3D 10 device.
    </p>
        <h4><a id="id-1.5.8"></a>Lifetime of Shared [D3D10] Objects</h4>
        <p>
        An OpenCL memory object created from a Direct3D 10 resource remains valid as long as the 
        corresponding Direct3D 10 resource has not been deleted. If the Direct3D 10 resource is deleted 
        through the Direct3D 10 API, subsequent use of the OpenCL memory object will result in 
        undefined behavior, including but not limited to possible OpenCL errors, data corruption, and 
        program termination.
    </p>
        <p>
        The successful creation of a cl_context against a Direct3D 10 device specified via the context 
        create parameter <code class="constant">CL_CONTEXT_D3D10_DEVICE_KHR</code> will increment the internal Direct3D 
        reference count on the specified Direct3D 10 device. The internal Direct3D reference count on 
        that Direct3D 10 device will be decremented when the OpenCL reference count on the returned 
        OpenCL context drops to zero.
    </p>
        <p>
        The OpenCL context and corresponding command-queues are dependent on the existence of the 
        Direct3D 10 device from which the OpenCL context was created. If the Direct3D 10 device is 
        deleted through the Direct3D 10 API, subsequent use of the OpenCL context will result in 
        undefined behavior, including but not limited to possible OpenCL errors, data corruption, and 
        program termination.
