VkBufferCaptureDescriptorDataInfoEXT(3)

# VkBufferCaptureDescriptorDataInfoEXT(3) Manual Page

## Name

VkBufferCaptureDescriptorDataInfoEXT - Structure specifying a buffer for descriptor capture

## C Specification

Information about the buffer to get descriptor buffer capture data for is passed in a `VkBufferCaptureDescriptorDataInfoEXT` structure:

Warning | This functionality is superseded by VK_EXT_descriptor_heap. See Legacy Functionality for more information.

    // Provided by VK_EXT_descriptor_buffer
    typedef struct VkBufferCaptureDescriptorDataInfoEXT {
        VkStructureType    sType;
        const void*        pNext;
        VkBuffer           buffer;
    } VkBufferCaptureDescriptorDataInfoEXT;

## Members

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

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

- `buffer` is the `VkBuffer` handle of the buffer to get opaque capture data for.

## Description

Valid Usage

- VUID-VkBufferCaptureDescriptorDataInfoEXT-buffer-08075
  `buffer` must have been created with VK_BUFFER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT set in VkBufferCreateInfo::`flags`

Valid Usage (Implicit)

- VUID-VkBufferCaptureDescriptorDataInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_BUFFER_CAPTURE_DESCRIPTOR_DATA_INFO_EXT

- VUID-VkBufferCaptureDescriptorDataInfoEXT-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkBufferCaptureDescriptorDataInfoEXT-buffer-parameter
  `buffer` must be a valid VkBuffer handle
