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.
