# OpenCL<sup>TM</sup> API Headers
This repository contains C language headers for the OpenCL API.
The authoritative public repository for these headers is located at:
https://github.com/KhronosGroup/OpenCL-Headers
Issues, proposed fixes for issues, and other suggested changes should be
created using Github.
## Branch Structure
The OpenCL API headers in this repository are Unified headers and are designed
to work with all released OpenCL versions. This differs from previous OpenCL
API headers, where version-specific API headers either existed in separate
branches, or in separate folders in a branch.
## Compiling for a Specific OpenCL Version
By default, the OpenCL API headers in this repository are for the latest
OpenCL version (currently OpenCL 2.2). To use these API headers to target
a different OpenCL version, an application may `#define` the preprocessor
value `CL_TARGET_OPENCL_VERSION` before including the OpenCL API headers.
The `CL_TARGET_OPENCL_VERSION` is a three digit decimal value representing
the OpenCL API version.
For example, to enforce usage of no more than the OpenCL 1.2 APIs, you may
include the OpenCL API headers as follows:
```
#define CL_TARGET_OPENCL_VERSION 120
#include <CL/opencl.h>
```
