C Specification

Bits which can be set in vkGetQueryPoolResults::flags and vkCmdCopyQueryPoolResults::flags, specifying how and when results are returned, are:

typedef enum VkQueryResultFlagBits {
    VK_QUERY_RESULT_64_BIT = 0x00000001,
    VK_QUERY_RESULT_WAIT_BIT = 0x00000002,
} VkQueryResultFlagBits;


  • 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.
