cl_khr_d3d11_sharing Provide interoperability between OpenCL and Direct3D 11.

##

#pragma OPENCL EXTENSION cl_khr_d3d11_sharing : enable

## Description

The goal of this extension is to provide interoperability between OpenCL and Direct3D 11. This is designed to function analogously to the OpenGL interoperability as defined in sections 9.7 and 9.8. If this extension is supported by an implementation, the string "cl_khr_d3d11_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.

The interfaces for this extension are provided in the header file `cl_d3d11.h`.

If the `cl_khr_d3d11_sharing` extension is supported, then the following functions are enabled:

- clGetDeviceIDsFromD3D11KHR
- clCreateFromD3D11BufferKHR
- clCreateFromD3D11Texture2DKHR
- clCreateFromD3D11Texture3DKHR
- clEnqueueAcquireD3D11ObjectsKHR
- clEnqueueReleaseD3D11ObjectsKHR

The OpenCL functions enabled by the `cl_khr_d3d11_sharing` extension allow applications to use Direct3D 11 resources as OpenCL memory objects. This allows efficient sharing of data between OpenCL and Direct3D 11. The OpenCL API may be used to execute kernels that read and/or write memory objects that are also Direct3D 11 resources. An OpenCL image object may be created from a Direct3D 11 texture resource. An OpenCL buffer object may be created from a Direct3D 11 buffer resource. OpenCL memory objects may be created from Direct3D 11 objects if and only if the OpenCL context has been created from a Direct3D 11 device.
