| # Introduction |
| |
| This page details the extensions that are supported by ANGLE. |
| |
| Specifications for GLES extensions can be found in the [Khronos OpenGL ES API |
| Registry](http://www.khronos.org/registry/gles/) |
| |
| Specifications for EGL extensions can be found in the [Khronos EGL API Registry] |
| (http://www.khronos.org/registry/egl/) |
| |
| Specifications for ANGLE-specific extensions can be found in the [ANGLE |
| extension registry] |

| ## EGL Extensions |
| |
| * EGL\_EXT\_create\_context\_robustness |
| * only reset notifications supported |
| * EGL\_ANGLE\_d3d\_share\_handle\_client\_buffer (fn2) |
| * EGL\_ANGLE\_query\_surface\_pointer |

| |
| ### Notes |
| |
| * fn1: extensions are only exposed if underlying D3D9 device has support for |
| the required features |
| * fn2: extensions are only exposed when running on D3D9Ex (ie Win Vista/7) |
| * fn3: extension is only exposed when swiftshader is present |
