## Name

VkPastPresentationTimingInfoEXT - Structure specifying swapchain present timing query parameters

Loading… please wait.

## C Specification

The `VkPastPresentationTimingInfoEXT` structure is defined as:

    // Provided by VK_EXT_present_timing
    typedef struct VkPastPresentationTimingInfoEXT {
        VkStructureType                     sType;
        const void*                         pNext;
        VkPastPresentationTimingFlagsEXT    flags;
        VkSwapchainKHR                      swapchain;
    } VkPastPresentationTimingInfoEXT;

## Members

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

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

- `flags` is a bitmask of VkPastPresentationTimingFlagBitsEXT specifying options for queries of past presentation timing information.

- `swapchain` is the swapchain to obtain presentation timing information for.

## Description

Valid Usage (Implicit)

- VUID-VkPastPresentationTimingInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PAST_PRESENTATION_TIMING_INFO_EXT`

- VUID-VkPastPresentationTimingInfoEXT-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkPastPresentationTimingInfoEXT-flags-parameter
  `flags` must be a valid combination of VkPastPresentationTimingFlagBitsEXT values

- VUID-VkPastPresentationTimingInfoEXT-swapchain-parameter
  `swapchain` must be a valid VkSwapchainKHR handle

Host Synchronization

- Host access to `swapchain` must be externally synchronized
