# vkDestroyDebugReportCallbackEXT(3) Manual Page

## Name

vkDestroyDebugReportCallbackEXT - Destroy a debug report callback object

Loading… please wait.

## C Specification

To destroy a `VkDebugReportCallbackEXT` object, call:

    // Provided by VK_EXT_debug_report
    void vkDestroyDebugReportCallbackEXT(
        VkInstance                                  instance,
        VkDebugReportCallbackEXT                    callback,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `instance` is the instance where the callback was created.

- `callback` is the VkDebugReportCallbackEXT object to destroy. `callback` is an externally synchronized object and must not be used on more than one thread at a time. This means that `vkDestroyDebugReportCallbackEXT` must not be called when a callback is active.

- `pAllocator` controls host memory allocation as described in the Memory Allocation chapter.

## Description

Valid Usage

- VUID-vkDestroyDebugReportCallbackEXT-instance-01242
  If `VkAllocationCallbacks` were provided when `callback` was created, a compatible set of callbacks must be provided here

- VUID-vkDestroyDebugReportCallbackEXT-instance-01243
  If no `VkAllocationCallbacks` were provided when `callback` was created, `pAllocator` must be `NULL`

Valid Usage (Implicit)

- VUID-vkDestroyDebugReportCallbackEXT-instance-parameter
  `instance` must be a valid VkInstance handle

- VUID-vkDestroyDebugReportCallbackEXT-callback-parameter
  If `callback` is not VK_NULL_HANDLE, `callback` must be a valid VkDebugReportCallbackEXT handle

- VUID-vkDestroyDebugReportCallbackEXT-pAllocator-parameter
  If `pAllocator` is not `NULL`, `pAllocator` must be a valid pointer to a valid VkAllocationCallbacks structure

- VUID-vkDestroyDebugReportCallbackEXT-callback-parent
  If `callback` is a valid handle, it must have been created, allocated, or retrieved from `instance`

Host Synchronization

- Host access to `callback` must be externally synchronized
