-- | vkCreateViSurfaceNN - Create a
-- 'Graphics.Vulkan.Extensions.VK_KHR_surface.VkSurfaceKHR' object for a VI
-- layer
--
-- = Parameters
--
-- -   @instance@ is the instance with which to associate the surface.
--
-- -   @pCreateInfo@ is a pointer to an instance of the
--     @VkViSurfaceCreateInfoNN@ 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](https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#memory-allocation)).
--
-- -   @pSurface@ points to a @VkSurfaceKHR@ handle in which the created
--     surface object is returned.
--
-- = Description
--
-- During the lifetime of a surface created using a particular
-- @nn@::@vi@::@NativeWindowHandle@ any attempts to create another surface
-- for the same @nn@::@vi@::@Layer@ and any attempts to connect to the same
-- @nn@::@vi@::@Layer@ through other platform mechanisms will have
-- undefined results.
--
-- The @currentExtent@ of a VI surface is always undefined. Applications
-- are expected to choose an appropriate size for the swapchain’s
-- @imageExtent@ (e.g., by matching the the result of a call to
-- @nn@::@vi@::@GetDisplayResolution@).
--
-- == Valid Usage (Implicit)
--
-- -   @instance@ /must/ be a valid @VkInstance@ handle
--
-- -   @pCreateInfo@ /must/ be a valid pointer to a valid
--     @VkViSurfaceCreateInfoNN@ structure
--
-- -   If @pAllocator@ is not @NULL@, @pAllocator@ /must/ be a valid
--     pointer to a valid @VkAllocationCallbacks@ structure
--
-- -   @pSurface@ /must/ be a valid pointer to a @VkSurfaceKHR@ handle
--
-- == Return Codes
--
-- [[Success](https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#fundamentals-successcodes)]
--     -   @VK_SUCCESS@
--
-- [[Failure](https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#fundamentals-errorcodes)]
--     -   @VK_ERROR_OUT_OF_HOST_MEMORY@
--
--     -   @VK_ERROR_OUT_OF_DEVICE_MEMORY@
--
--     -   @VK_ERROR_NATIVE_WINDOW_IN_USE_KHR@
