vkCreateViSurfaceNN - Create a SurfaceKHR object for a VI layer

Parameters

• instance is the instance with which to associate the surface.

• pCreateInfo is a pointer to a ViSurfaceCreateInfoNN structure containing parameters affecting the creation of the surface object.
• pAllocator is the allocator used for host memory allocated for the surface object when there is no more specific allocator available (see Memory Allocation).
• pSurface is a pointer to a SurfaceKHR handle in which the created surface object is returned.

Description

During the lifetime of a surface created using a particular nn::vi::NativeWindowHandle, applications must not attempt to create another surface for the same nn::vi::Layer or attempt to connect to the same nn::vi::Layer through other platform mechanisms.

If the native window is created with a specified size, currentExtent will reflect that size. In this case, applications should use the same size for the swapchain’s imageExtent. Otherwise, the currentExtent will have the special value (0xFFFFFFFF, 0xFFFFFFFF), indicating that applications are expected to choose an appropriate size for the swapchain’s imageExtent (e.g., by matching the result of a call to nn::vi::GetDisplayResolution).

Valid Usage (Implicit)

• instance must be a valid Instance handle

• pCreateInfo must be a valid pointer to a valid ViSurfaceCreateInfoNN structure
• If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
• pSurface must be a valid pointer to a SurfaceKHR handle

Return Codes

Success

• SUCCESS

Failure

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY
• ERROR_NATIVE_WINDOW_IN_USE_KHR

VkSurfaceKHR - Opaque handle to a surface object

Description

The VK_KHR_surface extension declares the SurfaceKHR object, and provides a function for destroying SurfaceKHR objects. Separate platform-specific extensions each provide a function for creating a SurfaceKHR object for the respective platform. From the application’s perspective this is an opaque handle, just like the handles of other Vulkan objects.
