# VkQueryResultFlagBits(3) Manual Page

## Name

VkQueryResultFlagBits - Bitmask specifying how and when query results are returned

Loading… please wait.

## 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.
