## Name

VkPhysicalDeviceAttachmentFeedbackLoopLayoutFeaturesEXT - Structure indicating support for a render feedback loop image layout

Loading… please wait.

## C Specification

The `VkPhysicalDeviceAttachmentFeedbackLoopLayoutFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_attachment_feedback_loop_layout
    typedef struct VkPhysicalDeviceAttachmentFeedbackLoopLayoutFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           attachmentFeedbackLoopLayout;
    } VkPhysicalDeviceAttachmentFeedbackLoopLayoutFeaturesEXT;

## Members

This structure describes the following feature:

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

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

- `attachmentFeedbackLoopLayout` indicates whether the implementation supports using `VK_IMAGE_LAYOUT_ATTACHMENT_FEEDBACK_LOOP_OPTIMAL_EXT` image layout for images created with `VK_IMAGE_USAGE_ATTACHMENT_FEEDBACK_LOOP_BIT_EXT`.

## Description

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceAttachmentFeedbackLoopLayoutFeaturesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ATTACHMENT_FEEDBACK_LOOP_LAYOUT_FEATURES_EXT`

## See Also

VK_EXT_attachment_feedback_loop_layout, VkBool32, VkStructureType
