vkGetPrivateData

To retrieve application-defined data from a slot associated with a Vulkan object, call:

void vkGetPrivateData(
    VkDevice device,
    VkObjectType objectType,
    uint64_t objectHandle,
    VkPrivateDataSlot privateDataSlot,
    uint64_t* pData);

pub fn get_private_data(
    device: vk::Device,
    object_type: vk::ObjectType,
    object_handle: u64,
    private_data_slot: vk::PrivateDataSlot,
    p_data: *mut u64,
);

void vkGetPrivateDataEXT(
    VkDevice device,
    VkObjectType objectType,
    uint64_t objectHandle,
    VkPrivateDataSlot privateDataSlot,
    uint64_t* pData);

pub fn get_private_data_ext(
    device: vk::Device,
    object_type: vk::ObjectType,
    object_handle: u64,
    private_data_slot: vk::PrivateDataSlot,
    p_data: *mut u64,
);

• device is the device that created the object
• objectType is a VkObjectType specifying the type of object data is associated with.
• objectHandle is a handle to the object data is associated with.
• privateDataSlot is a handle to a VkPrivateDataSlot specifying location of private data pointer storage.
• pData is a pointer to specify where application-defined data is returned. If privateDataSlot was not created with VK_PRIVATE_DATA_SLOT_CREATE_BASE_OBJECT_HANDLE_BIT_NV, 0 will be written in the absence of a previous call to vkSetPrivateData using the object specified by objectHandle. If privateDataSlot was created with VK_PRIVATE_DATA_SLOT_CREATE_BASE_OBJECT_HANDLE_BIT_NV, the implementation’s base handle for the object is written to pData. The base handle is the value of objectHandle as received by the implementation after traversal of the dispatch chain.
