C Specification
To query the set of time domains for which a physical device supports timestamp calibration, call:
// Provided by VK_KHR_calibrated_timestamps
VkResult vkGetPhysicalDeviceCalibrateableTimeDomainsKHR(
VkPhysicalDevice physicalDevice,
uint32_t* pTimeDomainCount,
VkTimeDomainKHR* pTimeDomains);
or the equivalent command
// Provided by VK_EXT_calibrated_timestamps
VkResult vkGetPhysicalDeviceCalibrateableTimeDomainsEXT(
VkPhysicalDevice physicalDevice,
uint32_t* pTimeDomainCount,
VkTimeDomainKHR* pTimeDomains);
Parameters
-
physicalDeviceis the physical device from which to query the set of calibrateable time domains. -
pTimeDomainCountis a pointer to an integer related to the number of calibrateable time domains available or queried, as described below. -
pTimeDomainsis eitherNULLor a pointer to an array of VkTimeDomainKHR values, indicating the supported calibrateable time domains.
Description
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.
