+ * of the created window, framebuffer and context, see @ref

+ *
+ * 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

+ * it.
+ *
+ * As long as at least one full screen window is not iconified, the screensaver
+ * is prohibited from starting.

+ *
+ * @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

+ * in the Mac Developer Library.
+ *
+ * @remark @macos The first time a window is created the menu bar is created.

+ * 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.
+ *

+ * [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,
