# VkDebugMarkerObjectTagInfoEXT(3) Manual Page

## Name

VkDebugMarkerObjectTagInfoEXT - Specify parameters of a tag to attach to an object

## C Specification

The `VkDebugMarkerObjectTagInfoEXT` structure is defined as:

    // Provided by VK_EXT_debug_marker
    typedef struct VkDebugMarkerObjectTagInfoEXT {
        VkStructureType               sType;
        const void*                   pNext;
        VkDebugReportObjectTypeEXT    objectType;
        uint64_t                      object;
        uint64_t                      tagName;
        size_t                        tagSize;
        const void*                   pTag;
    } VkDebugMarkerObjectTagInfoEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `objectType` is a VkDebugReportObjectTypeEXT specifying the type of the object to be named.

- `object` is the object to be tagged.

- `tagName` is a numerical identifier of the tag.

- `tagSize` is the number of bytes of data to attach to the object.

- `pTag` is a pointer to an array of `tagSize` bytes containing the data to be associated with the object.

## Description

The `tagName` parameter gives a name or identifier to the type of data being tagged. This can be used by debugging layers to easily filter for only data that can be used by that implementation.

Valid Usage

- VUID-VkDebugMarkerObjectTagInfoEXT-objectType-01493
  `objectType` must not be VK_DEBUG_REPORT_OBJECT_TYPE_UNKNOWN_EXT

- VUID-VkDebugMarkerObjectTagInfoEXT-object-01494
  `object` must not be VK_NULL_HANDLE

- VUID-VkDebugMarkerObjectTagInfoEXT-object-01495
  `object` must be a Vulkan object of the type associated with `objectType` as defined in https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#debug-report-object-types

Valid Usage (Implicit)

- VUID-VkDebugMarkerObjectTagInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_DEBUG_MARKER_OBJECT_TAG_INFO_EXT

- VUID-VkDebugMarkerObjectTagInfoEXT-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkDebugMarkerObjectTagInfoEXT-objectType-parameter
  `objectType` must be a valid VkDebugReportObjectTypeEXT value

- VUID-VkDebugMarkerObjectTagInfoEXT-pTag-parameter
  `pTag` must be a valid pointer to an array of `tagSize` bytes

- VUID-VkDebugMarkerObjectTagInfoEXT-tagSize-arraylength
  `tagSize` must be greater than `0`

Host Synchronization

- Host access to `object` must be externally synchronized
