## Name

VkBindHeapInfoEXT - Structure describing a device address range and implementation reservation for a descriptor heap

Loading… please wait.

## C Specification

`VkBindHeapInfoEXT` is defined as:

    // Provided by VK_EXT_descriptor_heap
    typedef struct VkBindHeapInfoEXT {
        VkStructureType            sType;
        const void*                pNext;
        VkDeviceAddressRangeEXT    heapRange;
        VkDeviceSize               reservedRangeOffset;
        VkDeviceSize               reservedRangeSize;
    } VkBindHeapInfoEXT;

## Members

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

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

- `heapRange` is a VkDeviceAddressRangeKHR defining the device address range used for the heap, inclusive of the implementation reserved range.

- `reservedRangeOffset` is the offset within `heapRange` to the start of the reserved range for the implementation.

- `reservedRangeSize` is the size of the reserved range for the implementation within `heapRange`.

## Description

Valid Usage (Implicit)

- VUID-VkBindHeapInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_BIND_HEAP_INFO_EXT

- VUID-VkBindHeapInfoEXT-pNext-pNext
  `pNext` must be `NULL`
