# VkDeviceOrHostAddressConstKHR(3) Manual Page

## Name

VkDeviceOrHostAddressConstKHR - Union specifying a const device or host address

## C Specification

The `VkDeviceOrHostAddressConstKHR` union is defined as:

    // Provided by VK_KHR_acceleration_structure, VK_NV_cooperative_vector
    typedef union VkDeviceOrHostAddressConstKHR {
        VkDeviceAddress    deviceAddress;
        const void*        hostAddress;
    } VkDeviceOrHostAddressConstKHR;

## Members

- `deviceAddress` is a buffer device address as returned by the vkGetBufferDeviceAddressKHR command.

- `hostAddress` is a const host memory address.
