+ * The created window, framebuffer and context may differ from what you

+ * 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.
+ *
+ * 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 window_hints_wnd) 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

+ * **By using the native access functions you assert that you know what you're
+ * doing and how to fix problems caused by using them. If you don't, you
+ * shouldn't be using them.**
+ *
+ * Before the inclusion of @ref glfw3native.h, you may define exactly one
+ * window system API macro and zero or more context creation API macros.
+ *
+ * The chosen backends must match those the library was compiled for. Failure
+ * to do this will cause a link-time error.
+ *
+ * The available window API macros are:
+ * * `GLFW_EXPOSE_NATIVE_WIN32`
+ * * `GLFW_EXPOSE_NATIVE_COCOA`
+ * * `GLFW_EXPOSE_NATIVE_X11`
+ * * `GLFW_EXPOSE_NATIVE_WAYLAND`
+ * * `GLFW_EXPOSE_NATIVE_MIR`
+ *
+ * The available context API macros are:
+ * * `GLFW_EXPOSE_NATIVE_WGL`
+ * * `GLFW_EXPOSE_NATIVE_NSGL`
+ * * `GLFW_EXPOSE_NATIVE_GLX`
+ * * `GLFW_EXPOSE_NATIVE_EGL`
+ *
+ * These macros select which of the native access functions that are declared
+ * and which platform-specific headers to include. It is then up your (by
+ * definition platform-specific) code to handle which of these should be
+ * defined.
