## 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.
