To query the set of time domains for which a physical device supports timestamp calibration, call:
// Provided by VK_EXT_calibrated_timestamps VkResult vkGetPhysicalDeviceCalibrateableTimeDomainsEXT( VkPhysicalDevice physicalDevice, uint32_t* pTimeDomainCount, VkTimeDomainEXT* pTimeDomains);
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.
NULLor a pointer to an array of VkTimeDomainEXT values, indicating the supported calibrateable time domains.
NULL, then the number of calibrateable time
domains supported for the given
physicalDevice is returned in
pTimeDomainCount must point to a variable set by the user
to the number of elements in the
pTimeDomains array, and on return the
variable is overwritten with the number of values actually written to
If the value of
pTimeDomainCount is less than the number of
calibrateable time domains supported, at most
will be written to
VK_INCOMPLETE will be
returned instead of
VK_SUCCESS, to indicate that not all the available
time domains were returned.
