} VkPresentTimeGOOGLE;
Members
-
presentID
is an application-provided identification value, that can be used with the results of vkGetPastPresentationTimingGOOGLE, in order to uniquely identify this present. In order to be useful to the application, it should be unique within some period of time that is meaningful to the application. -
desiredPresentTime
specifies that the image given should not be displayed to the user any earlier than this time.desiredPresentTime
is a time in nanoseconds, relative to a monotonically-increasing clock (e.g.CLOCK_MONOTONIC
(see clock_gettime(2)) on Android and Linux). A value of zero specifies that the presentation engine may display the image at any time. This is useful when the application desires to providepresentID
