   subtype uu_uint8_t is unsigned_char;
   subtype uu_uint16_t is unsigned_short;
   subtype uu_uint32_t is unsigned;
   subtype uu_uint64_t is unsigned_long;

--18jun2020: let's make size intensions explicit:

   type uint8_t is new uu_uint8_t;
	for uint8_t'size use 8;

   type uint16_t is new uu_uint16_t;
	for uint16_t'size use 16;

   type uint32_t is new uu_uint32_t;
	for uint32_t'size use 32;

   type uint64_t is new uu_uint64_t;
	for uint64_t'size use 64;

	--fastrgv:  this works fine too (in case of trouble):
	--type uint8_t  is mod 2**8;
	--for uint8_t'size use 8;
	--type uint16_t is mod 2**16;
	--for uint16_t'size use 16;
	--type uint32_t is mod 2**32;
	--for uint32_t'size use 32;
	--type uint64_t is mod 2**64;
	--for uint64_t'size use 64;

  -- *
  -- *  This function creates a window and its associated OpenGL or OpenGL ES

  -- *  should be created are specified with [window hints](@ref window_hints).
  -- *
  -- *  Successful creation does not change which context is current.  Before you

  -- *  parameter, see @ref context_sharing.
  -- *
  -- *  The created window, framebuffer and context may differ from what you
  -- *  requested, as not all parameters and hints are
  -- *  [hard constraints](@ref window_hints_hard).  This includes the size of the
  -- *  window, especially for full screen windows.  To query the actual attributes
  -- *  of the created window, framebuffer and context, see @ref
  -- *  glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize.
  -- *
  -- *  To create a full screen window, you need to specify the monitor the window
  -- *  will cover.  If no monitor is specified, the window will be windowed mode.
  -- *  Unless you have a way for the user to choose a specific monitor, it is
  -- *  recommended that you pick the primary monitor.  For more information on how
  -- *  to query connected monitors, see @ref monitor_monitors.
  -- *
  -- *  For full screen windows, the specified size becomes the resolution of the
  -- *  window's _desired video mode_.  As long as a full screen window is not
  -- *  iconified, the supported video mode most closely matching the desired video
  -- *  mode is set for the specified monitor.  For more information about full
  -- *  screen windows, including the creation of so called _windowed full screen_
  -- *  or _borderless full screen_ windows, see @ref window_windowed_full_screen.
  -- *
  -- *  Once you have created the window, you can switch it between windowed and
  -- *  full screen mode with @ref glfwSetWindowMonitor.  This will not affect its
  -- *  OpenGL or OpenGL ES context.
  -- *
  -- *  By default, newly created windows use the placement recommended by the
  -- *  window system.  To create the window at a specific position, make it
  -- *  initially invisible using the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window
  -- *  hint, set its [position](@ref window_pos) and then [show](@ref window_hide)
  -- *  it.
  -- *
  -- *  As long as at least one full screen window is not iconified, the screensaver
  -- *  is prohibited from starting.
  -- *
  -- *  Window systems put limits on window sizes.  Very large or very small window
  -- *  dimensions may be overridden by the window system on creation.  Check the
  -- *  actual [size](@ref window_size) after creation.
  -- *
  -- *  The [swap interval](@ref buffer_swap) is not set during window creation and
  -- *  the initial value may vary depending on driver settings and defaults.
  -- *
  -- *  @param[in] width The desired width, in screen coordinates, of the window.
  -- *  This must be greater than zero.
  -- *  @param[in] height The desired height, in screen coordinates, of the window.
  -- *  This must be greater than zero.
  -- *  @param[in] title The initial, UTF-8 encoded window title.
  -- *  @param[in] monitor The monitor to use for full screen mode, or `NULL` for
  -- *  windowed mode.

  -- *
  -- *  @remark @win32 If the executable has an icon resource named `GLFW_ICON,` it
  -- *  will be set as the initial icon for the window.  If no such icon is present,
  -- *  the `IDI_APPLICATION` icon will be used instead.  To set a different icon,
  -- *  see @ref glfwSetWindowIcon.
  -- *
  -- *  @remark @win32 The context to share resources with must not be current on
  -- *  any other thread.
  -- *
  -- *  @remark @macos The OS only supports forward-compatible core profile contexts
  -- *  for OpenGL versions 3.2 and later.  Before creating an OpenGL context of
  -- *  version 3.2 or later you must set the
  -- *  [GLFW_OPENGL_FORWARD_COMPAT](@ref GLFW_OPENGL_FORWARD_COMPAT_hint) and
  -- *  [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint) hints accordingly.
  -- *  OpenGL 3.0 and 3.1 contexts are not supported at all on macOS.
  -- *
  -- *  @remark @macos The GLFW window has no icon, as it is not a document
  -- *  window, but the dock icon will be the same as the application bundle's icon.
  -- *  For more information on bundles, see the
  -- *  [Bundle Programming Guide](https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/)
  -- *  in the Mac Developer Library.
  -- *
  -- *  @remark @macos The first time a window is created the menu bar is created.
  -- *  If GLFW finds a `MainMenu.nib` it is loaded and assumed to contain a menu
  -- *  bar.  Otherwise a minimal menu bar is created manually with common commands
  -- *  like Hide, Quit and About.  The About entry opens a minimal about dialog
  -- *  with information from the application's bundle.  Menu bar creation can be
  -- *  disabled entirely with the @ref GLFW_COCOA_MENUBAR init hint.
  -- *
  -- *  @remark @macos On OS X 10.10 and later the window frame will not be rendered
  -- *  at full resolution on Retina displays unless the
  -- *  [GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint)
  -- *  hint is `GLFW_TRUE` and the `NSHighResolutionCapable` key is enabled in the
  -- *  application bundle's `Info.plist`.  For more information, see
  -- *  [High Resolution Guidelines for OS X](https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Explained/Explained.html)
  -- *  in the Mac Developer Library.  The GLFW test and example programs use
  -- *  a custom `Info.plist` template for this, which can be found as
  -- *  `CMake/MacOSXBundleInfo.plist.in` in the source tree.
  -- *
  -- *  @remark @macos When activating frame autosaving with
  -- *  [GLFW_COCOA_FRAME_NAME](@ref GLFW_COCOA_FRAME_NAME_hint), the specified
  -- *  window size and position may be overridden by previously saved values.
  -- *
  -- *  @remark @x11 Some window managers will not respect the placement of
  -- *  initially hidden windows.
  -- *
  -- *  @remark @x11 Due to the asynchronous nature of X11, it may take a moment for
  -- *  a window to reach its requested state.  This means you may not be able to
  -- *  query the final size, position or other attributes directly after window
  -- *  creation.
  -- *
  -- *  @remark @x11 The class part of the `WM_CLASS` window property will by
  -- *  default be set to the window title passed to this function.  The instance
  -- *  part will use the contents of the `RESOURCE_NAME` environment variable, if
  -- *  present and not empty, or fall back to the window title.  Set the
  -- *  [GLFW_X11_CLASS_NAME](@ref GLFW_X11_CLASS_NAME_hint) and
  -- *  [GLFW_X11_INSTANCE_NAME](@ref GLFW_X11_INSTANCE_NAME_hint) window hints to
  -- *  override this.
  -- *
  -- *  @remark @wayland Compositors should implement the xdg-decoration protocol
  -- *  for GLFW to decorate the window properly.  If this protocol isn't
  -- *  supported, or if the compositor prefers client-side decorations, a very
  -- *  simple fallback frame will be drawn using the wp_viewporter protocol.  A
  -- *  compositor can still emit close, maximize or fullscreen events, using for
  -- *  instance a keybind mechanism.  If neither of these protocols is supported,
  -- *  the window won't be decorated.
  -- *
  -- *  @remark @wayland A full screen window will not attempt to change the mode,
  -- *  no matter what the requested size or refresh rate.
  -- *

  --! @brief Returns the layout-specific name of the specified printable key.
  -- *
  -- *  This function returns the name of the specified printable key, encoded as
  -- *  UTF-8.  This is typically the character that key would produce without any
  -- *  modifier keys, intended for displaying key bindings to the user.  For dead
  -- *  keys, it is typically the diacritic it would add to a character.
  -- *
  -- *  __Do not use this function__ for [text input](@ref input_char).  You will
  -- *  break text input for many languages even if it happens to work for yours.
  -- *
  -- *  If the key is `GLFW_KEY_UNKNOWN`, the scancode is used to identify the key,
  -- *  otherwise the scancode is ignored.  If you specify a non-printable key, or
  -- *  `GLFW_KEY_UNKNOWN` and a scancode that maps to a non-printable key, this
  -- *  function returns `NULL` but does not emit an error.
  -- *
  -- *  This behavior allows you to always pass in the arguments in the
  -- *  [key callback](@ref input_key) without modification.

  --! @brief Returns whether the specified queue family can present images.
  -- *
  -- *  This function returns whether the specified queue family of the specified

  -- *
  -- *  If Vulkan or the required window surface creation instance extensions are
  -- *  not available on the machine, or if the specified instance was not created
  -- *  with the required extensions, this function returns `GLFW_FALSE` and
  -- *  generates a @ref GLFW_API_UNAVAILABLE error.  Call @ref glfwVulkanSupported
  -- *  to check whether Vulkan is at least minimally available and @ref
  -- *  glfwGetRequiredInstanceExtensions to check what instance extensions are
  -- *  required.
  -- *
  -- *  @param[in] instance The instance that the physical device belongs to.
  -- *  @param[in] device The physical device that the queue family belongs to.
  -- *  @param[in] queuefamily The index of the queue family to query.
  -- *  @return `GLFW_TRUE` if the queue family supports presentation, or
  -- *  `GLFW_FALSE` otherwise.
  -- *
  -- *  @errors Possible errors include @ref GLFW_NOT_INITIALIZED, @ref
  -- *  GLFW_API_UNAVAILABLE and @ref GLFW_PLATFORM_ERROR.
  -- *
  -- *  @remark @macos This function currently always returns `GLFW_TRUE`, as the
  -- *  `VK_MVK_macos_surface` extension does not provide

  --! @brief Creates a Vulkan surface for the specified window.
  -- *
  -- *  This function creates a Vulkan surface for the specified window.
  -- *
  -- *  If the Vulkan loader or at least one minimally functional ICD were not found,
  -- *  this function returns `VK_ERROR_INITIALIZATION_FAILED` and generates a @ref
  -- *  GLFW_API_UNAVAILABLE error.  Call @ref glfwVulkanSupported to check whether
  -- *  Vulkan is at least minimally available.
  -- *
  -- *  If the required window surface creation instance extensions are not
  -- *  available or if the specified instance was not created with these extensions
  -- *  enabled, this function returns `VK_ERROR_EXTENSION_NOT_PRESENT` and
  -- *  generates a @ref GLFW_API_UNAVAILABLE error.  Call @ref
  -- *  glfwGetRequiredInstanceExtensions to check what instance extensions are
  -- *  required.
  -- *
  -- *  The window surface cannot be shared with another API so the window must
  -- *  have been created with the [client api hint](@ref GLFW_CLIENT_API_attrib)
  -- *  set to `GLFW_NO_API` otherwise it generates a @ref GLFW_INVALID_VALUE error
  -- *  and returns `VK_ERROR_NATIVE_WINDOW_IN_USE_KHR`.
  -- *
  -- *  The window surface must be destroyed before the specified Vulkan instance.
  -- *  It is the responsibility of the caller to destroy the window surface.  GLFW
  -- *  does not destroy it for you.  Call `vkDestroySurfaceKHR` to destroy the
  -- *  surface.
  -- *
  -- *  @param[in] instance The Vulkan instance to create the surface in.
  -- *  @param[in] window The window to create the surface for.
  -- *  @param[in] allocator The allocator to use, or `NULL` to use the default
  -- *  allocator.
  -- *  @param[out] surface Where to store the handle of the surface.  This is set
  -- *  to `VK_NULL_HANDLE` if an error occurred.
  -- *  @return `VK_SUCCESS` if successful, or a Vulkan error code if an
  -- *  [error](@ref error_handling) occurred.
  -- *
  -- *  @errors Possible errors include @ref GLFW_NOT_INITIALIZED, @ref
  -- *  GLFW_API_UNAVAILABLE, @ref GLFW_PLATFORM_ERROR and @ref GLFW_INVALID_VALUE
  -- *
  -- *  @remark If an error occurs before the creation call is made, GLFW returns
  -- *  the Vulkan error code most appropriate for the error.  Appropriate use of
  -- *  @ref glfwVulkanSupported and @ref glfwGetRequiredInstanceExtensions should
  -- *  eliminate almost all occurrences of these errors.
  -- *
  -- *  @remark @macos This function currently only supports the
  -- *  `VK_MVK_macos_surface` extension from MoltenVK.
  -- *
  -- *  @remark @macos This function creates and sets a `CAMetalLayer` instance for
  -- *  the window content view, which is required for MoltenVK to function.
  -- *
  -- *  @thread_safety This function may be called from any thread.  For
  -- *  synchronization details of Vulkan objects, see the Vulkan specification.
