# VkCalibratedTimestampInfoKHR(3) Manual Page

## Name

VkCalibratedTimestampInfoKHR - Structure specifying the input parameters of a calibrated timestamp query

Loading… please wait.

## C Specification

The `VkCalibratedTimestampInfoKHR` structure is defined as:

    // Provided by VK_KHR_calibrated_timestamps
    typedef struct VkCalibratedTimestampInfoKHR {
        VkStructureType    sType;
        const void*        pNext;
        VkTimeDomainKHR    timeDomain;
    } VkCalibratedTimestampInfoKHR;

or the equivalent

    // Provided by VK_EXT_calibrated_timestamps
    typedef VkCalibratedTimestampInfoKHR VkCalibratedTimestampInfoEXT;

## Members

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

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

- `timeDomain` is a VkTimeDomainKHR value specifying the time domain from which the calibrated timestamp value should be returned.

## Description

Valid Usage

- VUID-VkCalibratedTimestampInfoKHR-timeDomain-02354
  `timeDomain` must be one of the VkTimeDomainKHR values returned by vkGetPhysicalDeviceCalibrateableTimeDomainsKHR

Valid Usage (Implicit)

- VUID-VkCalibratedTimestampInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_CALIBRATED_TIMESTAMP_INFO_KHR`

- VUID-VkCalibratedTimestampInfoKHR-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkCalibratedTimestampInfoKHR-timeDomain-parameter
  `timeDomain` must be a valid VkTimeDomainKHR value
