# VkDescriptorBufferBindingPushDescriptorBufferHandleEXT(3) Manual Page

## Name

VkDescriptorBufferBindingPushDescriptorBufferHandleEXT - Structure specifying push descriptor buffer binding information

Loading… please wait.

## C Specification

When the `VkPhysicalDeviceDescriptorBufferPropertiesEXT`::`bufferlessPushDescriptors` property is VK_FALSE, the `VkBuffer` handle of the buffer for push descriptors is passed in a `VkDescriptorBufferBindingPushDescriptorBufferHandleEXT` 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Warning | This functionality is superseded by VK_EXT_descriptor_heap.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 VkDescriptorBufferBindingPushDescriptorBufferHandleEXT {
        VkStructureType    sType;
        const void*        pNext;
        VkBuffer           buffer;
    } VkDescriptorBufferBindingPushDescriptorBufferHandleEXT;

## 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 for push descriptors.

## Description

Valid Usage

- VUID-VkDescriptorBufferBindingPushDescriptorBufferHandleEXT-bufferlessPushDescriptors-08059
  `VkPhysicalDeviceDescriptorBufferPropertiesEXT`::`bufferlessPushDescriptors` must be VK_FALSE

Valid Usage (Implicit)

  `sType` must be VK_STRUCTURE_TYPE_DESCRIPTOR_BUFFER_BINDING_PUSH_DESCRIPTOR_BUFFER_HANDLE_EXT

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