## Name

VkPhysicalDeviceLayeredApiPropertiesKHR - Structure describing a single layered implementation underneath the Vulkan physical device

Loading… please wait.

## C Specification

The `VkPhysicalDeviceLayeredApiPropertiesKHR` structure is defined as:

    // Provided by VK_KHR_maintenance7
    typedef struct VkPhysicalDeviceLayeredApiPropertiesKHR {
        VkStructureType                  sType;
        void*                            pNext;
        uint32_t                         vendorID;
        uint32_t                         deviceID;
        VkPhysicalDeviceLayeredApiKHR    layeredAPI;
        char                             deviceName[VK_MAX_PHYSICAL_DEVICE_NAME_SIZE];
    } VkPhysicalDeviceLayeredApiPropertiesKHR;

## Members

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

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

- `vendorID` is a unique identifier for the vendor of the layered implementation.

- `deviceID` is a unique identifier for the layered implementation among devices available from the vendor.

- `layeredAPI` is a VkPhysicalDeviceLayeredApiKHR specifying the API implemented by the layered implementation.

- `deviceName` is an array of `VK_MAX_PHYSICAL_DEVICE_NAME_SIZE` `char` containing a null-terminated UTF-8 string which is the name of the device.

## Description

If `layeredAPI` is `VK_PHYSICAL_DEVICE_LAYERED_API_VULKAN_KHR`, additional Vulkan-specific information can be queried by including the VkPhysicalDeviceLayeredApiVulkanPropertiesKHR structure in the `pNext` chain. Otherwise if such a structure is included in the `pNext` chain, it is ignored.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceLayeredApiPropertiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_LAYERED_API_PROPERTIES_KHR`

- VUID-VkPhysicalDeviceLayeredApiPropertiesKHR-pNext-pNext
  `pNext` must be `NULL` or a pointer to a valid instance of VkPhysicalDeviceLayeredApiVulkanPropertiesKHR

- VUID-VkPhysicalDeviceLayeredApiPropertiesKHR-sType-unique
  The `sType` value of each structure in the `pNext` chain must be unique
