## Name

VkQueueFamilyOwnershipTransferPropertiesKHR - Structure describing queue family ownership transfer properties

Loading… please wait.

## C Specification

The VkQueueFamilyOwnershipTransferPropertiesKHR structure is defined as:

    // Provided by VK_KHR_maintenance9
    typedef struct VkQueueFamilyOwnershipTransferPropertiesKHR {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           optimalImageTransferToQueueFamilies;
    } VkQueueFamilyOwnershipTransferPropertiesKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `optimalImageTransferToQueueFamilies` is a bitmask of queue family indices that indicates which queue families belonging to the same logical device support implicitly acquiring optimal image resources owned by this queue family, without the resources' contents becoming undefined.

## Description

If this structure is included in the `pNext` chain of the VkQueueFamilyProperties2 structure passed to vkGetPhysicalDeviceQueueFamilyProperties2, then it is filled with the queue family ownership properties for the specified queue family.

Valid Usage (Implicit)

- VUID-VkQueueFamilyOwnershipTransferPropertiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_QUEUE_FAMILY_OWNERSHIP_TRANSFER_PROPERTIES_KHR`
