C Specification

The VkDebugUtilsObjectTagInfoEXT structure is defined as:

// Provided by VK_EXT_debug_utils
typedef struct VkDebugUtilsObjectTagInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    VkObjectType       objectType;
    uint64_t           objectHandle;
    uint64_t           tagName;
    size_t             tagSize;
    const void*        pTag;
} VkDebugUtilsObjectTagInfoEXT;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • objectType is a VkObjectType specifying the type of the object to be named.

  • objectHandle 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.


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-VkDebugUtilsObjectTagInfoEXT-objectType-01908
    objectType must not be VK_OBJECT_TYPE_UNKNOWN

  • VUID-VkDebugUtilsObjectTagInfoEXT-objectHandle-01910
    objectHandle must be a valid Vulkan handle of the type associated with objectType as defined in the VkObjectType and Vulkan Handle Relationship table

Valid Usage (Implicit)
  • VUID-VkDebugUtilsObjectTagInfoEXT-sType-sType

  • VUID-VkDebugUtilsObjectTagInfoEXT-pNext-pNext
    pNext must be NULL

  • VUID-VkDebugUtilsObjectTagInfoEXT-objectType-parameter
    objectType must be a valid VkObjectType value

  • VUID-VkDebugUtilsObjectTagInfoEXT-pTag-parameter
    pTag must be a valid pointer to an array of tagSize bytes

  • VUID-VkDebugUtilsObjectTagInfoEXT-tagSize-arraylength
    tagSize must be greater than 0
