            <p> C language header files for the OpenCL API are found in the <a

            
                href="https://github.com/KhronosGroup/OpenCL-Headers">

            
                KhronosGroup/OpenCL-Headers</a> Github repository. In the past, there

            
                were different header files for each OpenCL version. The header files

            
                have now been unified - a single set of headers supports all OpenCL API

            
                versions - and the API version defined by the headers at compilation

            
                time is determined as described in the README.md in that repository.

	versions - and the API version defined by the headers at compilation
	time is determined as described in the README.md in that repository.
