        VkDevice                                    device,
        const VkPrivateDataSlotCreateInfo*          pCreateInfo,
        const VkAllocationCallbacks*                pAllocator,
        VkPrivateDataSlot*                          pPrivateDataSlot);

or the equivalent command

    // Provided by VK_EXT_private_data
    VkResult vkCreatePrivateDataSlotEXT(
        VkDevice                                    device,
        const VkPrivateDataSlotCreateInfo*          pCreateInfo,
        const VkAllocationCallbacks*                pAllocator,
        VkPrivateDataSlot*                          pPrivateDataSlot);

## Parameters

- `pCreateInfo` is a pointer to a `VkPrivateDataSlotCreateInfo`

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

- `pPrivateDataSlot` is a pointer to a VkPrivateDataSlot handle in which the resulting private data slot is returned
