## Name

VkPhysicalDeviceDriverProperties - Structure containing driver identification information

Loading... please wait.

## C Specification

To query the properties of the driver corresponding to a physical device, add a VkPhysicalDeviceDriverProperties structure to the `pNext` chain of the VkPhysicalDeviceProperties2 structure. The `VkPhysicalDeviceDriverProperties` structure is defined as:

    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

    typedef VkPhysicalDeviceDriverProperties VkPhysicalDeviceDriverPropertiesKHR;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension specific 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 version of the Vulkan conformance test this driver is conformant against (see VkConformanceVersion).

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

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DRIVER_PROPERTIES`
