C Specification
The VkPresentTimeGOOGLE structure is defined as:
typedef struct VkPresentTimeGOOGLE {
uint32_t presentID;
uint64_t desiredPresentTime;
} VkPresentTimeGOOGLE;
Members
-
presentIDis 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. -
desiredPresentTimespecifies that the image given should not be displayed to the user any earlier than this time.desiredPresentTimeis 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, but does not need a specificdesiredPresentTime.
