# VkRenderPassInputAttachmentAspectCreateInfo(3) Manual Page

## Name

VkRenderPassInputAttachmentAspectCreateInfo - Structure specifying, for a given subpass/input attachment pair, which aspect can: be read.

Loading… please wait.

## C Specification

The `VkRenderPassInputAttachmentAspectCreateInfo` structure is defined as:

    // Provided by VK_VERSION_1_1
    typedef struct VkRenderPassInputAttachmentAspectCreateInfo {
        VkStructureType                            sType;
        const void*                                pNext;
        uint32_t                                   aspectReferenceCount;
        const VkInputAttachmentAspectReference*    pAspectReferences;
    } VkRenderPassInputAttachmentAspectCreateInfo;

or the equivalent

    // Provided by VK_KHR_maintenance2
    typedef VkRenderPassInputAttachmentAspectCreateInfo VkRenderPassInputAttachmentAspectCreateInfoKHR;

## Members

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

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

- `aspectReferenceCount` is the number of elements in the `pAspectReferences` array.

- `pAspectReferences` is a pointer to an array of `aspectReferenceCount` VkInputAttachmentAspectReference structures containing a mask describing which aspect(s) can be accessed for a given input attachment within a given subpass.

## Description

To specify which aspects of an input attachment can be read, add a VkRenderPassInputAttachmentAspectCreateInfo structure to the `pNext` chain of the VkRenderPassCreateInfo structure:

An application can access any aspect of an input attachment that does not have a specified aspect mask in the `pAspectReferences` array. Otherwise, an application must not access aspect(s) of an input attachment other than those in its specified aspect mask.

Valid Usage (Implicit)

- VUID-VkRenderPassInputAttachmentAspectCreateInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_RENDER_PASS_INPUT_ATTACHMENT_ASPECT_CREATE_INFO`

- VUID-VkRenderPassInputAttachmentAspectCreateInfo-pAspectReferences-parameter
  `pAspectReferences` must be a valid pointer to an array of `aspectReferenceCount` valid VkInputAttachmentAspectReference structures

- VUID-VkRenderPassInputAttachmentAspectCreateInfo-aspectReferenceCount-arraylength
  `aspectReferenceCount` must be greater than `0`
