# VkPresentTimingsInfoEXT(3) Manual Page

## Name

VkPresentTimingsInfoEXT - Array of VkPresentTimingInfoEXT to chain with VkPresentInfoKHR

Loading… please wait.

## C Specification

When the `presentAtAbsoluteTime` or `presentAtRelativeTime` feature is enabled, an application can instruct the presentation engine to attempt to display an image at a specified time, or for a minimum duration, by including the `VkPresentTimingsInfoEXT` structure in the `pNext` chain of the VkPresentInfoKHR structure.

The `VkPresentTimingsInfoEXT` structure is defined as:

    // Provided by VK_EXT_present_timing
    typedef struct VkPresentTimingsInfoEXT {
        VkStructureType                  sType;
        const void*                      pNext;
        uint32_t                         swapchainCount;
        const VkPresentTimingInfoEXT*    pTimingInfos;
    } VkPresentTimingsInfoEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `swapchainCount` is the number of swapchains being presented to by this command.

- `pTimingInfos` is `NULL` or a pointer to an array of `VkPresentTimingInfoEXT` elements with `swapchainCount` entries. If not `NULL`, each element of `pTimingInfos` contains timing information for the presentation of the image corresponding to the entry in the `VkPresentInfoKHR`::`pImageIndices` array.

## Description

Valid Usage

- VUID-VkPresentTimingsInfoEXT-swapchainCount-12233
  `swapchainCount` must be equal to VkPresentInfoKHR::`swapchainCount`

- VUID-VkPresentTimingsInfoEXT-pSwapchains-12234
  All swapchains in VkPresentInfoKHR::`pSwapchains` must have been created with the VkSwapchainCreateInfoKHR::`flags` field containing `VK_SWAPCHAIN_CREATE_PRESENT_TIMING_BIT_EXT`

- VUID-VkPresentTimingsInfoEXT-pSwapchains-12235
  For each member of `VkPresentInfoKHR`::`pSwapchains`, if the associated VkPresentTimingInfoEXT::`targetTime` is not zero, the swapchain’s current present mode must be `VK_PRESENT_MODE_FIFO_LATEST_READY_KHR`, `VK_PRESENT_MODE_FIFO_KHR` or `VK_PRESENT_MODE_FIFO_RELAXED_KHR`

Valid Usage (Implicit)

- VUID-VkPresentTimingsInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PRESENT_TIMINGS_INFO_EXT`

- VUID-VkPresentTimingsInfoEXT-pTimingInfos-parameter
  If `pTimingInfos` is not `NULL`, `pTimingInfos` must be a valid pointer to an array of `swapchainCount` valid VkPresentTimingInfoEXT structures

- VUID-VkPresentTimingsInfoEXT-swapchainCount-arraylength
  `swapchainCount` must be greater than `0`
