# VkPresentTimeGOOGLE(3) Manual Page

## Name

VkPresentTimeGOOGLE - The earliest time image should be presented

Loading… please wait.

## C Specification

The `VkPresentTimeGOOGLE` structure is defined as:

    // Provided by VK_GOOGLE_display_timing
    typedef struct VkPresentTimeGOOGLE {
        uint32_t    presentID;
        uint64_t    desiredPresentTime;
    } 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 provide `presentID`,

## Description

    but does not need a specific pname:desiredPresentTime.
