# VkSwapchainCalibratedTimestampInfoEXT(3) Manual Page

## Name

VkSwapchainCalibratedTimestampInfoEXT - Structure specifying the swapchain to calibrate a swapchain-local timestamp query

Loading… please wait.

## C Specification

The `VkSwapchainCalibratedTimestampInfoEXT` structure is defined as:

    // Provided by VK_EXT_present_timing
    typedef struct VkSwapchainCalibratedTimestampInfoEXT {
        VkStructureType           sType;
        const void*               pNext;
        VkSwapchainKHR            swapchain;
        VkPresentStageFlagsEXT    presentStage;
        uint64_t                  timeDomainId;
    } VkSwapchainCalibratedTimestampInfoEXT;

## Members

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

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

- `swapchain` is the swapchain to retrieve the swapchain-local timestamp from.

- `presentStage` is zero or a VkPresentStageFlagsEXT value used to identify a single present stage when calibrating a timestamp in the VK_TIME_DOMAIN_PRESENT_STAGE_LOCAL_EXT time domain.

- `timeDomainId` is the id for the opaque time domain being calibrated.

## Description

`timeDomainId` must be an id previously reported by vkGetSwapchainTimeDomainPropertiesEXT for `swapchain`. If the `timeDomainId` is no longer supported by the `swapchain`, implementations may report zero as the calibrated timestamp value.

Valid Usage

- VUID-VkSwapchainCalibratedTimestampInfoEXT-timeDomain-12228
  If the `timeDomain` member of the VkCalibratedTimestampInfoKHR structure in this structure’s `pNext` chain is VK_TIME_DOMAIN_PRESENT_STAGE_LOCAL_EXT, `presentStage` must specify one and only one present stage

Valid Usage (Implicit)

- VUID-VkSwapchainCalibratedTimestampInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_SWAPCHAIN_CALIBRATED_TIMESTAMP_INFO_EXT

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

- VUID-VkSwapchainCalibratedTimestampInfoEXT-presentStage-parameter
  `presentStage` must be a valid combination of VkPresentStageFlagBitsEXT values
