vkDestroyDeferredOperationKHR

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

void vkDestroyDeferredOperationKHR(
    VkDevice device,
    VkDeferredOperationKHR operation,
    const VkAllocationCallbacks* pAllocator);

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.

If VkAllocationCallbacks were provided when operation was created, a compatible set of callbacks must be provided here

If no VkAllocationCallbacks were provided when operation was created, pAllocator must be NULL

operation must be completed

device must be a valid VkDevice handle

If operation is not VK_NULL_HANDLE, operation must be a valid VkDeferredOperationKHR handle

If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

If operation is a valid handle, it must have been created, allocated, or retrieved from device
