vkGetPrivateData

Retrieve data associated with a Vulkan object

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. 0 will be written in the absence of a previous call to vkSetPrivateData using the object specified by objectHandle.

Due to platform details on Android, implementations might not be able to reliably return 0 from calls to vkGetPrivateData for VkSwapchainKHR objects on which vkSetPrivateData has not previously been called. This erratum is exclusive to the Android platform and objects of type VkSwapchainKHR.
