vkGetPhysicalDeviceCalibrateableTimeDomainsKHR

To query the set of time domains for which a physical device supports timestamp calibration, call:

VkResult vkGetPhysicalDeviceCalibrateableTimeDomainsKHR(
    VkPhysicalDevice physicalDevice,
    uint32_t* pTimeDomainCount,
    VkTimeDomainKHR* pTimeDomains);

or the equivalent command

VkResult vkGetPhysicalDeviceCalibrateableTimeDomainsEXT(
    VkPhysicalDevice physicalDevice,
    uint32_t* pTimeDomainCount,
    VkTimeDomainKHR* pTimeDomains);

• physicalDevice is the physical device from which to query the set of calibrateable time domains.
• pTimeDomainCount is a pointer to an integer related to the number of calibrateable time domains available or queried, as described below.
• pTimeDomains is either NULL or a pointer to an array of VkTimeDomainKHR values, indicating the supported calibrateable time domains.

If pTimeDomains is NULL, then the number of calibrateable time domains supported for the given physicalDevice is returned in pTimeDomainCount. Otherwise, pTimeDomainCount must point to a variable set by the application to the number of elements in the pTimeDomains array, and on return the variable is overwritten with the number of values actually written to pTimeDomains. If the value of pTimeDomainCount is less than the number of calibrateable time domains supported, at most pTimeDomainCount values will be written to pTimeDomains, and VK_INCOMPLETE will be returned instead of VK_SUCCESS, to indicate that not all the available time domains were returned.
