       cl_khr_dx9_media_sharing - Provide interoperability between OpenCL and selecgted adapter
       APIs (only DX9 at this time).

       #pragma OPENCL EXTENSION
       cl_khr_dx9_media_sharing : enable


       The interfaces for this extension are provided in the header file cl_dx9_media_sharing.h.

       If the cl_khr_dx9_media_sharing extension is supported, then the following functions are

       ·   clGetDeviceIDsFromDX9MediaAdapterKHR(3clc).RE

           ·   clCreateFromDX9MediaSurfaceKHR(3clc).RE

               ·   clEnqueueAcquireDX9MediaSurfacesKHR(3clc).RE

                   ·   clEnqueueReleaseDX9MediaSurfacesKHR(3clc).RE

                       The OpenCL functions enabled by the cl_khr_dx9_media_sharing extension
                       allow applications to use media surfaces as OpenCL memory objects. This
                       allows efficient sharing of data between OpenCL and selected adapter APIs
                       (only DX9 for now). If this extension is supported, an OpenCL image object
                       can be created from a media surface and the OpenCL API can be used to
                       execute kernels that read and/or write memory objects that are media
                       surfaces. Note that OpenCL memory objects may be created from the adapter
                       media surface if and only if the OpenCL context has been created from that

                       If this extension is supported by an implementation, the string
                       "cl_khr_dx9_media_sharing" will be present in the CL_PLATFORM_EXTENSIONS
                       or CL_DEVICE_EXTENSIONS string described in the table of allowed values
                       for param_name for clGetDeviceInfo(3clc)

                       As currently proposed the interfaces for this extension would be provided
                       in cl_dx9_media_sharing.h.
