# VkObjectType(3) Manual Page

## Name

VkObjectType - Specify an enumeration to track object handle types

Loading… please wait.

## C Specification

The VkObjectType enumeration defines values, each of which corresponds to a specific Vulkan handle type. These values can be used to associate debug information with a particular type of object through one or more extensions.
