# VkBufferDeviceAddressInfo(3) Manual Page

## Name

VkBufferDeviceAddressInfo - Structure specifying the buffer to query an address for

Loading… please wait.

## C Specification

The `VkBufferDeviceAddressInfo` structure is defined as:

    // Provided by VK_VERSION_1_2
    typedef struct VkBufferDeviceAddressInfo {
        VkStructureType    sType;
        const void*        pNext;
        VkBuffer           buffer;
    } VkBufferDeviceAddressInfo;

or the equivalent

    // Provided by VK_KHR_buffer_device_address
    typedef VkBufferDeviceAddressInfo VkBufferDeviceAddressInfoKHR;

or the equivalent

    // Provided by VK_EXT_buffer_device_address
    typedef VkBufferDeviceAddressInfo VkBufferDeviceAddressInfoEXT;

## Members

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

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

- `buffer` specifies the buffer whose address is being queried.

## Description

Valid Usage

- VUID-VkBufferDeviceAddressInfo-buffer-02600
  If `buffer` is non-sparse and was not created with the `VK_BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT` flag, then it must be bound completely and contiguously to a single `VkDeviceMemory` object

- VUID-VkBufferDeviceAddressInfo-buffer-02601
  `buffer` must have been created with `VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT`

Valid Usage (Implicit)

- VUID-VkBufferDeviceAddressInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_BUFFER_DEVICE_ADDRESS_INFO`

- VUID-VkBufferDeviceAddressInfo-pNext-pNext
  `pNext` must be `NULL`

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