# vkGetDeviceAccelerationStructureCompatibilityKHR(3) Manual Page

## Name

vkGetDeviceAccelerationStructureCompatibilityKHR - Check if a serialized acceleration structure is compatible with the current device

Loading… please wait.

## C Specification

To check if a serialized acceleration structure is compatible with the current device call:

    // Provided by VK_KHR_acceleration_structure
    void vkGetDeviceAccelerationStructureCompatibilityKHR(
        VkDevice                                    device,
        const VkAccelerationStructureVersionInfoKHR* pVersionInfo,
        VkAccelerationStructureCompatibilityKHR*    pCompatibility);

## Parameters

- `device` is the device to check the version against.

- `pVersionInfo` is a pointer to a VkAccelerationStructureVersionInfoKHR structure specifying version information to check against the device.

- `pCompatibility` is a pointer to a VkAccelerationStructureCompatibilityKHR value in which compatibility information is returned.

## Description

Valid Usage

- VUID-vkGetDeviceAccelerationStructureCompatibilityKHR-accelerationStructure-08928
  The `VkPhysicalDeviceAccelerationStructureFeaturesKHR`::`accelerationStructure` feature must be enabled

Valid Usage (Implicit)

- VUID-vkGetDeviceAccelerationStructureCompatibilityKHR-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkGetDeviceAccelerationStructureCompatibilityKHR-pVersionInfo-parameter
  `pVersionInfo` must be a valid pointer to a valid VkAccelerationStructureVersionInfoKHR structure

- VUID-vkGetDeviceAccelerationStructureCompatibilityKHR-pCompatibility-parameter
  `pCompatibility` must be a valid pointer to a VkAccelerationStructureCompatibilityKHR value
