C Specification
Bits which can be set in vkGetQueryPoolResults::flags
and
vkCmdCopyQueryPoolResults::flags
, specifying how and when
results are returned, are:
// Provided by VK_VERSION_1_0
typedef enum VkQueryResultFlagBits {
VK_QUERY_RESULT_64_BIT = 0x00000001,
VK_QUERY_RESULT_WAIT_BIT = 0x00000002,
VK_QUERY_RESULT_WITH_AVAILABILITY_BIT = 0x00000004,
VK_QUERY_RESULT_PARTIAL_BIT = 0x00000008,
#ifdef VK_ENABLE_BETA_EXTENSIONS
// Provided by VK_KHR_video_queue
VK_QUERY_RESULT_WITH_STATUS_BIT_KHR = 0x00000010,
#endif
} VkQueryResultFlagBits;
Description
-
VK_QUERY_RESULT_64_BIT
specifies the results will be written as an array of 64-bit unsigned integer values. If this bit is not set, the results will be written as an array of 32-bit unsigned integer values. -
VK_QUERY_RESULT_WAIT_BIT
specifies that Vulkan will wait for each query’s status to become available before retrieving its results. -
VK_QUERY_RESULT_WITH_AVAILABILITY_BIT
specifies that the availability status accompanies the results. -
VK_QUERY_RESULT_PARTIAL_BIT
specifies that returning partial results is acceptable. -
VK_QUERY_RESULT_WITH_STATUS_BIT_KHR
specifies that the last value returned in the query is a VkQueryResultStatusKHR value.
