VV::V1::AppInstance struct

#include <VaultedVulkan/VV_Initialization.hpp>

An object that manages the represented application process state within the GPU.

Other Name: Application State Container

Vulkan has no global state reference: Every application must keep track of their state using an instance object.

Application Instance Specification

Derived classes

struct VV::V2::AppInstance

An object that manages the represented application process state within the GPU.

Public types

struct AppInfo

A structure that specifies to the Vulkan driver information about an application that will run an instance.

struct CreateInfo

Structure specifying parameters of a newly created instance.

struct ValidationFeatures

Used when creating a Vulkan app instance and want to enable specific validation features. (Added to the Next chain).

struct ValidationFlags

Used when creating a Vulkan app instance and want to disable validation checks.

using Memory = V0::Memory

using Handle = VkInstance

Opaque handle to an instance object.

using CreateFlags = Bitfield<EUndefined, VkInstanceCreateFlags>

Reserved for future use...

Public static functions

static auto Create(const CreateInfo& _info, const Memory::AllocationCallbacks* _allocator, Handle& _handle) -> EResult

Create a new Vulkan application instance.

static void Destroy(Handle _handle, const Memory::AllocationCallbacks* _allocator)

Destroy an application instance of Vulkan.

static auto GetVersion(ui32& _versionContainer) -> EResult

Query the version of application instance-level functionality supported by the implementation.

static auto QueryAvailableLayers(ui32& _numContainer, LayerProperties* _propertiesContainer) -> EResult

Query the available layers.

static auto QueryAvailableAppExtensions(RoCStr _layerName, ui32& _numProperties, ExtensionProperties* _propertiesContainer) -> EResult

Query the available instance extensions.

static auto QueryPhysicalDeviceListing(Handle _handle, ui32* _numDevices, PhysicalDevice::Handle* _deviceListing) -> EResult

Retrieve a list of physical device objects representing the physical devices installed in the system, or get the number of them.

static auto QueryPhysicalDeviceGroups(Handle _handle, ui32* _numGroups, PhysicalDevice::Group* _groupProperties) -> EResult

template<typename ReturnType>

static auto GetProcedureAddress(Handle& _handle, RoCStr _procedureName) -> std::enable_if<std::bool_constant<std::is_pointer<ReturnType>::value && std::is_function<typename std::remove_pointer<ReturnType>::type>::value>::value, ReturnType>::type

Function pointers for all Vulkan commands can be obtained with this command.
