# VkToolPurposeFlagBitsEXT(3) Manual Page

## Name

VkToolPurposeFlagBitsEXT - Bitmask specifying the purposes of an active tool

## C Specification

Bits which can be set in VkDeviceQueueCreateInfo::`purposes` specifying the purposes of an active tool are:

    typedef enum VkToolPurposeFlagBitsEXT {
        VK_TOOL_PURPOSE_VALIDATION_BIT_EXT = 0x00000001,
        VK_TOOL_PURPOSE_PROFILING_BIT_EXT = 0x00000002,
        VK_TOOL_PURPOSE_TRACING_BIT_EXT = 0x00000004,
        VK_TOOL_PURPOSE_ADDITIONAL_FEATURES_BIT_EXT = 0x00000008,
        VK_TOOL_PURPOSE_MODIFYING_FEATURES_BIT_EXT = 0x00000010,
        VK_TOOL_PURPOSE_DEBUG_REPORTING_BIT_EXT = 0x00000020,
        VK_TOOL_PURPOSE_DEBUG_MARKERS_BIT_EXT = 0x00000040,
        VK_TOOL_PURPOSE_FLAG_BITS_MAX_ENUM_EXT = 0x7FFFFFFF
    } VkToolPurposeFlagBitsEXT;

## Description

- `VK_TOOL_PURPOSE_VALIDATION_BIT_EXT` specifies that the tool provides validation of API usage.

- `VK_TOOL_PURPOSE_PROFILING_BIT_EXT` specifies that the tool provides profiling of API usage.

- `VK_TOOL_PURPOSE_TRACING_BIT_EXT` specifies that the tool is capturing data about the application’s API usage, including anything from simple logging to capturing data for later replay.

- `VK_TOOL_PURPOSE_ADDITIONAL_FEATURES_BIT_EXT` specifies that the tool provides additional API features/extensions on top of the underlying implementation.

- `VK_TOOL_PURPOSE_MODIFYING_FEATURES_BIT_EXT` specifies that the tool modifies the API features/limits/extensions presented to the application.

- `VK_TOOL_PURPOSE_DEBUG_REPORTING_BIT_EXT` specifies that the tool reports additional information to the application via callbacks specified by vkCreateDebugReportCallbackEXT or vkCreateDebugUtilsMessengerEXT

- `VK_TOOL_PURPOSE_DEBUG_MARKERS_BIT_EXT` specifies that the tool consumes debug markers or object debug annotation, queue labels, or command buffer labels
