VkSubresourceLayout2(3)

# VkSubresourceLayout2(3) Manual Page

## Name

VkSubresourceLayout2 - Structure specifying subresource layout

## C Specification

Information about the layout of the image subresource is returned in a `VkSubresourceLayout2` structure:

    // Provided by VK_VERSION_1_4
    typedef struct VkSubresourceLayout2 {
        VkStructureType        sType;
        void*                  pNext;
        VkSubresourceLayout    subresourceLayout;
    } VkSubresourceLayout2;

    // Provided by VK_KHR_maintenance5
    // Equivalent to VkSubresourceLayout2
    typedef VkSubresourceLayout2 VkSubresourceLayout2KHR;

    // Provided by VK_EXT_host_image_copy, VK_EXT_image_compression_control
    // Equivalent to VkSubresourceLayout2
    typedef VkSubresourceLayout2 VkSubresourceLayout2EXT;

## Members

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

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

- `subresourceLayout` is a VkSubresourceLayout structure.

## Description

Valid Usage (Implicit)

- VUID-VkSubresourceLayout2-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_SUBRESOURCE_LAYOUT_2

- VUID-VkSubresourceLayout2-pNext-pNext
  Each `pNext` member of any structure (including this one) in the `pNext` chain must be either `NULL` or a pointer to a valid instance of VkImageCompressionPropertiesEXT or VkSubresourceHostMemcpySize

- VUID-VkSubresourceLayout2-sType-unique
  The `sType` value of each structure in the `pNext` chain must be unique
