| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p><em>Extensions</em> are optional features which may be supported by OpenCL |
| implementations. |
| Extensions are not required to be supported by a conformant OpenCL |
| implementation, but are expected to be widely available, and in some cases |
| may define functionality that is likely to be required in a future revision |
| of the OpenCL specification.</p> |
| </div> |
| <div class="paragraph"> |
| <p>In the past, this document contained full specification language for |
| Khronos-approved <code>khr</code> extensions, described in terms of changes to the core |
| OpenCL Specification. |
| This extension language has now been integrated into the OpenCL 3.0 |
| Specification, and can be read in context there.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The remaining parts of this document describe general issues in <em>using</em> |
| extensions, such as API <a href="#naming-convention-for-optional-extensions">Naming |
| Conventions for Optional Extensions</a>; OpenCL C |
| <a href="#compiler-directives-for-optional-extensions">Compiler Directives for |
| Optional Extensions</a>; and <a href="#getting-opencl-api-extension-function-pointers">Getting OpenCL API Extension Function Pointers</a>.</p> |

| <div class="paragraph"> |
| <p>In addition, there is a section on <a href="#spirv_extensions">Extensions to the |
| OpenCL SPIR-V Environment</a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Finally, the <a href="#quick-reference">Quick Reference</a> appendix summarizes khr |
| extensions and links to them in the OpenCL API Specification. |
| In some cases, extensions are mostly or entirely to the OpenCL C language |
| rather than to the OpenCL API. |
| Such extensions can be reached by following the links in the API |
| Specification extension appendices.</p> |

| <h3 id="naming-convention-for-optional-extensions"><a class="anchor" href="#naming-convention-for-optional-extensions"></a>1.1. Naming Convention for Optional Extensions</h3> |
| <div class="paragraph"> |
| <p>OpenCL extensions approved by the OpenCL working group use the following |
| naming convention:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>A unique <em>name string</em> of the form <code>"<strong>cl_khr_<<em>name</em>></strong>"</code> is associated |
| with each extension. |
| If the extension is supported by an implementation, this string will be |
| present in the implementation’s <code>CL_PLATFORM_<wbr>EXTENSIONS</code> string or |
| <code>CL_DEVICE_<wbr>EXTENSIONS</code> string.</p> |
| </li> |
| <li> |
| <p>All API functions defined by the extension will have names of the form |
| <strong>cl<<em>function_name</em>>KHR</strong>.</p> |
| </li> |
| <li> |
| <p>All enumerants defined by the extension will have names of the form |
| <strong>CL_<<em>enum_name</em>>_KHR.</strong></p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>Functions and enumerants defined by extensions that are promoted to |
| core features will have their <strong>KHR</strong> affix removed. |
| OpenCL implementations of such later revisions must also export the name |
| strings of promoted extensions in the <code>CL_PLATFORM_<wbr>EXTENSIONS</code> or |
| <code>CL_DEVICE_<wbr>EXTENSIONS</code> string, and support the <strong>KHR</strong>-affixed versions of |
| functions and enumerants as a transition aid.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Vendor extensions are strongly encouraged to follow a similar naming |
| convention:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>A unique <em>name string</em> of the form <code>"<strong>cl_<<em>vendor_name</em>>_<<em>name></em></strong>"</code> |

| present in the implementation’s <code>CL_PLATFORM_<wbr>EXTENSIONS</code> string or |
| <code>CL_DEVICE_<wbr>EXTENSIONS</code> string.</p> |
| </li> |
| <li> |
| <p>All API functions defined by the vendor extension will have names of the |
| form <strong>cl<<em>function_name</em>><<em>vendor_name</em>></strong>.</p> |

| <div class="paragraph"> |
| <p>The <strong>#pragma OPENCL EXTENSION</strong> directive controls the behavior of the OpenCL |

| extension approved by the OpenCL working group and will have names of the |
| form <strong>cl_<<em>vendor_name</em>>_<<em>name</em>></strong> for vendor extensions. |
| The token <strong>all</strong> means that the behavior applies to all extensions supported |

| <div class="paragraph"> |
| <p>The <strong><code>#pragma OPENCL EXTENSION</code></strong> directive is a simple, low-level mechanism |

| It does not define policies such as which combinations are appropriate; |
| those must be defined elsewhere. |
| The order of directives matter in setting the behavior for each extension. |
| Directives that occur later override those seen earlier. |
| The <strong>all</strong> variant sets the behavior for all extensions, overriding all |

| <p>Every extension which affects the OpenCL language semantics, syntax or adds |

| <div class="paragraph"> |

| A return value of <code>NULL</code> indicates that the specified function does not |

| A non-<code>NULL</code> return value for <strong>clGetExtensionFunctionAddressForPlatform</strong> |

| </div> |
| <div class="paragraph"> |
| <p><strong>clGetExtensionFunctionAddressForPlatform</strong> may not be used to query for core |

| For extension functions that may be queried using |
