# vkDestroyDeferredOperationKHR(3) Manual Page

## Name

vkDestroyDeferredOperationKHR - Destroy a deferred operation handle

Loading… please wait.

## C Specification

When a deferred operation is completed, the application can destroy the tracking object by calling:

    // Provided by VK_KHR_deferred_host_operations
    void vkDestroyDeferredOperationKHR(
        VkDevice                                    device,
        VkDeferredOperationKHR                      operation,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the device which owns `operation`.

- `operation` is the completed operation to be destroyed.

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

## Description

Valid Usage

- VUID-vkDestroyDeferredOperationKHR-operation-03434
  If `VkAllocationCallbacks` were provided when `operation` was created, a compatible set of callbacks must be provided here

- VUID-vkDestroyDeferredOperationKHR-operation-03435
  If no `VkAllocationCallbacks` were provided when `operation` was created, `pAllocator` must be `NULL`

- VUID-vkDestroyDeferredOperationKHR-operation-03436
  `operation` must be completed

Valid Usage (Implicit)

- VUID-vkDestroyDeferredOperationKHR-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkDestroyDeferredOperationKHR-operation-parameter
  If `operation` is not VK_NULL_HANDLE, `operation` must be a valid VkDeferredOperationKHR handle

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

- VUID-vkDestroyDeferredOperationKHR-operation-parent
  If `operation` is a valid handle, it must have been created, allocated, or retrieved from `device`

Host Synchronization

- Host access to `operation` must be externally synchronized
