C Specification
To query the set of time domains for which a physical device supports timestamp calibration, call:
VkResult vkGetPhysicalDeviceCalibrateableTimeDomainsEXT(
VkPhysicalDevice physicalDevice,
uint32_t* pTimeDomainCount,
VkTimeDomainEXT* pTimeDomains);
Parameters
-
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 eitherNULL
or a pointer to an array of VkTimeDomainEXT 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 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
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
.
If pTimeDomainCount
is smaller than the number of calibrateable time
domains supported for the given physicalDevice
, VK_INCOMPLETE
will be returned instead of VK_SUCCESS
to indicate that not all the
available values were returned.
