-- | vkCreateWin32SurfaceKHR - Create a
-- 'Graphics.Vulkan.Extensions.VK_KHR_surface.VkSurfaceKHR' object for an
-- Win32 native window
--
-- = Parameters
--
-- -   @instance@ is the instance to associate the surface with.
--
-- -   @pCreateInfo@ is a pointer to an instance of the
--     @VkWin32SurfaceCreateInfoKHR@ 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.
--
-- == Valid Usage (Implicit)
--
-- -   @instance@ /must/ be a valid @VkInstance@ handle
--
-- -   @pCreateInfo@ /must/ be a valid pointer to a valid
--     @VkWin32SurfaceCreateInfoKHR@ 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
--
