Class ANDROIDNativeFenceSync
This extension enables the creation of EGL fence sync objects that are associated with a native synchronization fence object that is referenced using a file descriptor. These EGL fence sync objects have nearly identical semantics to those defined by the KHR_fence_sync extension, except that they have an additional attribute storing the file descriptor referring to the native fence object.
This extension assumes the existence of a native fence synchronization object that behaves similarly to an EGL fence sync object. These native objects must have a signal status like that of an EGLSyncKHR object that indicates whether the fence has ever been signaled. Once signaled the native object's signal status may not change again.
Requires EGL 1.1
and KHR_fence_sync
