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,
// Provided by VK_KHR_video_queue
VK_QUERY_RESULT_WITH_STATUS_BIT_KHR = 0x00000010,
} 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. See result status query for information on how an application can determine whether the use of this flag bit is supported.
