             This extension is to provide interoperability between OpenCL and Direct3D 10. This
 is designed to function analogously to the OpenGL interoperability as enabled by
 <a class="citerefentry" href="cl_khr_gl_sharing.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_gl_sharing</span></span></a>. If this extension is supported by an implementation, the string cl_khr_d3d10_sharing will

 in table 4.3.

             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>
         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 CL_CONTEXT_D3D10_DEVICE_KHR 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.

	<p>
	This extension is to provide interoperability between OpenCL and Direct3D 10. This
	is designed to function analogously to the OpenGL interoperability as enabled by
	<a class="citerefentry" href="cl_khr_gl_sharing.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_gl_sharing</span></span></a>. If this extension is supported by an implementation, the string cl_khr_d3d10_sharing will
	be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described
	in table 4.3.

	<p>
	The interfaces for this extension are provided in the header file <code class="code">cl_d3d10.h.</code>.

	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>
	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 CL_CONTEXT_D3D10_DEVICE_KHR 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.
