| EGL Extension #?? |
| |
| Dependencies |
| |
| This extension is written against the wording of the EGL 1.5 |
| Specification. |
| |
| Overview |
| |
| This extension allows an application that uses a Google Games |
| Platform surface to associate a Google Games Platform frame token |
| with an eglSwapBuffers operation. |
| |
| It is based on the Vulkan extension VK_GGP_frame_token. |
| |
| New Types |
| |
| This is a 64-bit unsigned type that represents a GGP frame token. |
| |
| typedef khronos_uint64_t EGLFrameTokenANGLE; |
| |
| New Procedures and Functions |
| |
| EGLBoolean eglSwapBuffersWithFrameTokenANGLE( |
| EGLDisplay dpy, |
| EGLSurface surface, |
| EGLFrameTokenANGLE frametoken); |
| |
| New Tokens |
| |
| None |
| |
| Additions to the EGL 1.5 Specification |
| |
| Add the following to section 3.10.1 "Posting to a Window": |
| |
| A Google Games Platform frame token can be specified when posting a color |
| buffer to a window by calling |
| |
| EGLBoolean eglSwapBuffersWithFrameTokenANGLE( |
| EGLDisplay dpy, |
| EGLSurface surface, |
| EGLFrameTokenANGLE frametoken); |
| |
| The behaviour of eglSwapBuffersWithFrameTokenANGLE is identical to that |
| of eglSwapBuffers except that the behaviour is undefined when <frametoken> |
| is not a valid GgpFrameToken. |
| |
| Issues |
| |
| None yet. |
