        VkPrivateDataSlot                           privateDataSlot,
        const VkAllocationCallbacks*                pAllocator);

or the equivalent command

    // Provided by VK_EXT_private_data
    void vkDestroyPrivateDataSlotEXT(
        VkDevice                                    device,
        VkPrivateDataSlot                           privateDataSlot,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the logical device associated with the creation of the object(s) holding the private data slot.

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

Valid Usage (Implicit)

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

- VUID-vkDestroyPrivateDataSlot-privateDataSlot-parameter
  If `privateDataSlot` is not VK_NULL_HANDLE, `privateDataSlot` must be a valid VkPrivateDataSlot handle

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