C Specification

To get the opaque descriptor data for a buffer, call:

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 This functionality is superseded by VK_EXT_descriptor_heap.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

Parameters

  • device is the logical device that gets the data.

  • pInfo is a pointer to a VkBufferCaptureDescriptorDataInfoEXT structure specifying the buffer.

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

  • VUID-vkGetBufferOpaqueCaptureDescriptorDataEXT-pData-parameter
    pData must be a pointer value
