## Name

vkCreateDeferredOperationKHR - Create a deferred operation handle

Loading… please wait.

## C Specification

To construct the tracking object for a deferred command, call:

    // Provided by VK_KHR_deferred_host_operations
    VkResult vkCreateDeferredOperationKHR(
        VkDevice                                    device,
        const VkAllocationCallbacks*                pAllocator,
        VkDeferredOperationKHR*                     pDeferredOperation);

## Parameters

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

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

- `pDeferredOperation` is a pointer to a handle in which the created VkDeferredOperationKHR is returned.

## Description

Valid Usage (Implicit)

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

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

- VUID-vkCreateDeferredOperationKHR-pDeferredOperation-parameter
  `pDeferredOperation` must be a valid pointer to a VkDeferredOperationKHR handle

- VUID-vkCreateDeferredOperationKHR-device-queuecount
  The device must have been created with at least `1` queue

Return Codes

On success, this command returns

  - `VK_SUCCESS`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`
