# VkCommandBufferInheritanceDescriptorHeapInfoEXT(3) Manual Page

## Name

VkCommandBufferInheritanceDescriptorHeapInfoEXT - Structure specifying command buffer inheritance information

Loading… please wait.

## C Specification

If the `pNext` chain of VkCommandBufferInheritanceInfo includes a `VkCommandBufferInheritanceDescriptorHeapInfoEXT` structure, then that structure indicates that the secondary will use the same descriptor heaps as the primary command buffer.

The `VkCommandBufferInheritanceDescriptorHeapInfoEXT` structure is defined as:

    // Provided by VK_EXT_descriptor_heap
    typedef struct VkCommandBufferInheritanceDescriptorHeapInfoEXT {
        VkStructureType             sType;
        const void*                 pNext;
        const VkBindHeapInfoEXT*    pSamplerHeapBindInfo;
        const VkBindHeapInfoEXT*    pResourceHeapBindInfo;
    } VkCommandBufferInheritanceDescriptorHeapInfoEXT;

## Members

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

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

- `pSamplerHeapBindInfo` specifies the VkBindHeapInfoEXT of the sampler heap bound using vkCmdBindSamplerHeapEXT in the primary. If this is `NULL`, it indicates that no sampler heap is bound.

- `pResourceHeapBindInfo` specifies the VkBindHeapInfoEXT of the resource heap bound using vkCmdBindResourceHeapEXT in the primary. If this is `NULL`, it indicates that no resource heap is bound.

## Description

If this structure is not present, the behavior is as if `pSamplerHeapBindInfo` and `pResourceHeapBindInfo` were both `NULL`.

Valid Usage

- VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-descriptorHeap-11200
  If the `descriptorHeap` feature is not enabled, `pSamplerHeapBindInfo` must be `NULL`

- VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-descriptorHeap-11201
  If the `descriptorHeap` feature is not enabled, `pResourceHeapBindInfo` must be `NULL`

- VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pSamplerHeapBindInfo-11470
  If `pSamplerHeapBindInfo` is not `NULL`, `pSamplerHeapBindInfo->heapRange` must be a device address range allocated to the application from a buffer created with the VK_BUFFER_USAGE_DESCRIPTOR_HEAP_BIT_EXT usage flag set

- VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pResourceHeapBindInfo-11471
  If `pResourceHeapBindInfo` is not `NULL`, `pResourceHeapBindInfo->heapRange` must be a device address range allocated to the application from a buffer created with the VK_BUFFER_USAGE_DESCRIPTOR_HEAP_BIT_EXT usage flag set

Valid Usage (Implicit)

- VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_COMMAND_BUFFER_INHERITANCE_DESCRIPTOR_HEAP_INFO_EXT

- VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pSamplerHeapBindInfo-parameter
  If `pSamplerHeapBindInfo` is not `NULL`, `pSamplerHeapBindInfo` must be a valid pointer to a valid VkBindHeapInfoEXT structure

- VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pResourceHeapBindInfo-parameter
  If `pResourceHeapBindInfo` is not `NULL`, `pResourceHeapBindInfo` must be a valid pointer to a valid VkBindHeapInfoEXT structure
