## Name

VkQueryControlFlagBits - Bitmask specifying constraints on a query

## C Specification

Bits which can be set in vkCmdBeginQuery::`flags`, specifying constraints on the types of queries that can be performed, are:

    typedef enum VkQueryControlFlagBits {
        VK_QUERY_CONTROL_PRECISE_BIT = 0x00000001,
        VK_QUERY_CONTROL_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
    } VkQueryControlFlagBits;

## Description

- `VK_QUERY_CONTROL_PRECISE_BIT` specifies the precision of occlusion queries.
