# vkGetDeferredOperationResultKHR(3) Manual Page

## Name

vkGetDeferredOperationResultKHR - Query the result of a deferred operation

Loading… please wait.

## C Specification

The `vkGetDeferredOperationResultKHR` function is defined as:

    // Provided by VK_KHR_deferred_host_operations
    VkResult vkGetDeferredOperationResultKHR(
        VkDevice                                    device,
        VkDeferredOperationKHR                      operation);

## Parameters

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

- `operation` is the operation whose deferred result is being queried.

## Description

If no command has been deferred on `operation`, `vkGetDeferredOperationResultKHR` returns `VK_SUCCESS`.

If the deferred operation is pending, `vkGetDeferredOperationResultKHR` returns `VK_NOT_READY`.

If the deferred operation is complete, it returns the appropriate return value from the original command. This value must be one of the VkResult values which could have been returned by the original command if the operation had not been deferred.

Valid Usage (Implicit)

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

- VUID-vkGetDeferredOperationResultKHR-operation-parameter
  `operation` must be a valid VkDeferredOperationKHR handle

- VUID-vkGetDeferredOperationResultKHR-operation-parent
  `operation` must have been created, allocated, or retrieved from `device`

Return Codes

On success, this command returns

  - `VK_SUCCESS`

  - `VK_NOT_READY`

This command does not return any failure codes
