C Specification

To get the opaque capture descriptor data for an image view, call:

Warning
 This functionality is superseded by VK_EXT_descriptor_heap. See Legacy Functionality for more information. 
// Provided by VK_EXT_descriptor_buffer
VkResult vkGetImageViewOpaqueCaptureDescriptorDataEXT(
    VkDevice                                    device,
    const VkImageViewCaptureDescriptorDataInfoEXT* pInfo,
    void*                                       pData);

Parameters

  • device is the logical device that gets the data.

  • pInfo is a pointer to a VkImageViewCaptureDescriptorDataInfoEXT structure specifying the image view.

  • pData is a pointer to an application-allocated buffer where the data will be written.
