## Name

VkPhysicalDeviceDriverProperties - Structure containing driver identification information

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDriverProperties` structure is defined as:

    // Provided by VK_VERSION_1_2
    typedef struct VkPhysicalDeviceDriverProperties {
        VkStructureType         sType;
        void*                   pNext;
        VkDriverId              driverID;
        char                    driverName[VK_MAX_DRIVER_NAME_SIZE];
        char                    driverInfo[VK_MAX_DRIVER_INFO_SIZE];
        VkConformanceVersion    conformanceVersion;
    } VkPhysicalDeviceDriverProperties;

or the equivalent

    // Provided by VK_KHR_driver_properties
    typedef VkPhysicalDeviceDriverProperties VkPhysicalDeviceDriverPropertiesKHR;

## Members

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

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

## Description

- `driverID` is a unique identifier for the driver of the physical device.

- `driverName` is an array of `VK_MAX_DRIVER_NAME_SIZE` `char` containing a null-terminated UTF-8 string which is the name of the driver.

- `driverInfo` is an array of `VK_MAX_DRIVER_INFO_SIZE` `char` containing a null-terminated UTF-8 string with additional information about the driver.

- `conformanceVersion` is the latest version of the Vulkan conformance test that the implementor has successfully tested this driver against prior to release (see VkConformanceVersion).

If the `VkPhysicalDeviceDriverProperties` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

These are properties of the driver corresponding to a physical device.

`driverID` must be immutable for a given driver across instances, processes, driver versions, and system reboots.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDriverProperties-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DRIVER_PROPERTIES`
