| EGL Extension XXX |
| |
| Extension Type |
| |
| EGL Client Extension |
| |
| Dependencies |
| |
| OpenGL ES 3.1 is required. |
| |
| EGL_KHR_get_all_proc_addresses is required. |
| |
| EGL_EXT_client_extensions is required. |
| |
| Overview |
| |
| This extension adds new OpenGL ES entry points that allow the user to pass the current EGL |
| context as a function parameter. This allows users to skip lookup of the thread's current |
| context upon entry. |
| |
| New Types |
| |
| None. |
| |
| New Procedures and Functions |
| |
| For every OpenGL ES entry point available through eglGetProcAddress, an additional entry point |
| is made available. The entry points have the form of: |
| |
| <return value> gl<entry point name>ContextANGLE(GLeglContextANGLE context, <entry point parameters>) |
| |
| If a function already has an extension suffix, this form still applies. |
| |
| New Tokens |
| |
| None. |
| |
| Additions to the EGL Specification |
| |
| When using OpenGL ES as a client library, the ContextANGLE entry points allow the user to |
| pass the current EGL context as a function parameter to provide better performance than |
| looking up the current EGL context at every GL entry point. |
| |
| Calls made with an explicit context provide no additional validation for the passed context |
| parameter. |
| |
| Calls made with an explicit context will generate errors under the same conditions as they |
| would without an explicit context. Any instances of undefined behaviour without specifying |
| an explicit context are still undefined when specifying an explicit context. |
| |
| When an EGL context that is not current is explicitly passed, the resulting behavior is |
| undefined. |
| |
| Issues |
| |
| None. |
