## Name

VkRenderPassSubpassFeedbackCreateInfoEXT - Request for feedback about the creation of subpass

Loading… please wait.

## C Specification

Feedback about the creation of a subpass can be obtained by including a `VkRenderPassSubpassFeedbackCreateInfoEXT` structure in the `pNext` chain of VkSubpassDescription2. `VkRenderPassSubpassFeedbackCreateInfoEXT` structure is defined as:

Warning | This functionality is deprecated by Vulkan Version 1.4. See Deprecated Functionality for more information.

    // Provided by VK_EXT_subpass_merge_feedback
    typedef struct VkRenderPassSubpassFeedbackCreateInfoEXT {
        VkStructureType                        sType;
        const void*                            pNext;
        VkRenderPassSubpassFeedbackInfoEXT*    pSubpassFeedback;
    } VkRenderPassSubpassFeedbackCreateInfoEXT;

## Members

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

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

- `pSubpassFeedback` is a pointer to a VkRenderPassSubpassFeedbackInfoEXT structure in which feedback is returned.

## Description

Valid Usage (Implicit)

- VUID-VkRenderPassSubpassFeedbackCreateInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_RENDER_PASS_SUBPASS_FEEDBACK_CREATE_INFO_EXT`

- VUID-VkRenderPassSubpassFeedbackCreateInfoEXT-pSubpassFeedback-parameter
  `pSubpassFeedback` must be a valid pointer to a VkRenderPassSubpassFeedbackInfoEXT structure
