-- | vkCreateHeadlessSurfaceEXT - Create a headless

--
-- = Parameters
--
-- -   @instance@ is the instance to associate the surface with.
--
-- -   @pCreateInfo@ is a pointer to a 'HeadlessSurfaceCreateInfoEXT'
--     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
--     <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#memory-allocation Memory Allocation>).
--
-- -   @pSurface@ is a pointer to a 'Vulkan.Extensions.Handles.SurfaceKHR'
--     handle in which the created surface object is returned.
--
-- == Valid Usage (Implicit)
--
-- -   @instance@ /must/ be a valid 'Vulkan.Core10.Handles.Instance' handle
--
-- -   @pCreateInfo@ /must/ be a valid pointer to a valid
--     'HeadlessSurfaceCreateInfoEXT' structure
