## Name

VkOpaqueCaptureDescriptorDataCreateInfoEXT - Structure specifying opaque capture descriptor data

Loading… please wait.

## C Specification

The `VkOpaqueCaptureDescriptorDataCreateInfoEXT` structure is defined as:

    // Provided by VK_EXT_descriptor_buffer
    typedef struct VkOpaqueCaptureDescriptorDataCreateInfoEXT {
        VkStructureType    sType;
        const void*        pNext;
        const void*        opaqueCaptureDescriptorData;
    } VkOpaqueCaptureDescriptorDataCreateInfoEXT;

## Members

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

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

- `opaqueCaptureDescriptorData` is a pointer to an application-allocated buffer containing opaque capture data retrieved using vkGetBufferOpaqueCaptureDescriptorDataEXT, vkGetImageOpaqueCaptureDescriptorDataEXT, vkGetImageViewOpaqueCaptureDescriptorDataEXT, vkGetTensorOpaqueCaptureDescriptorDataARM, vkGetTensorViewOpaqueCaptureDescriptorDataARM, vkGetSamplerOpaqueCaptureDescriptorDataEXT, or vkGetAccelerationStructureOpaqueCaptureDescriptorDataEXT.

## Description

During replay, opaque descriptor capture data can be specified by adding a `VkOpaqueCaptureDescriptorDataCreateInfoEXT` structure to the relevant `pNext` chain of a VkBufferCreateInfo, VkImageCreateInfo, VkImageViewCreateInfo, VkSamplerCreateInfo, VkTensorCreateInfoARM, VkTensorViewCreateInfoARM, VkAccelerationStructureCreateInfoNV or VkAccelerationStructureCreateInfoKHR structure.

Valid Usage (Implicit)

- VUID-VkOpaqueCaptureDescriptorDataCreateInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_OPAQUE_CAPTURE_DESCRIPTOR_DATA_CREATE_INFO_EXT`

- VUID-VkOpaqueCaptureDescriptorDataCreateInfoEXT-opaqueCaptureDescriptorData-parameter
  `opaqueCaptureDescriptorData` must be a pointer value
