+@page window_guide Window guide
+
+@tableofcontents
+
+This guide introduces the window related functions of GLFW. For details on
+a specific function in this category, see the @ref window. There are also
+guides for the other areas of GLFW.
+

+
+
+@section window_object Window objects
+
+The @ref GLFWwindow object encapsulates both a window and a context. They are
+created with @ref glfwCreateWindow and destroyed with @ref glfwDestroyWindow, or
+@ref glfwTerminate, if any remain. As the window and context are inseparably
+linked, the object pointer is used as both a context and window handle.
+
+To see the event stream provided to the various window related callbacks, run
+the `events` test program.
+
+
+@subsection window_creation Window creation
+
+A window and its OpenGL or OpenGL ES context are created with @ref
+glfwCreateWindow, which returns a handle to the created window object. For
+example, this creates a 640 by 480 windowed mode window:
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+@endcode
+
+If window creation fails, `NULL` will be returned, so it is necessary to check
+the return value.
+
+The window handle is passed to all window related functions and is provided to
+along with all input events, so event handlers can tell which window received
+the event.
+
+
+@subsubsection window_full_screen Full screen windows
+
+To create a full screen window, you need to specify which monitor the window
+should use. In most cases, the user's primary monitor is a good choice.
+For more information about retrieving monitors, see @ref monitor_monitors.
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", glfwGetPrimaryMonitor(), NULL);
+@endcode
+
+Full screen windows cover the entire display area of a monitor, have no border
+or decorations.
+
+Windowed mode windows can be made full screen by setting a monitor with @ref
+glfwSetWindowMonitor, and full screen ones can be made windowed by unsetting it
+with the same function.
+
+Each field of the @ref GLFWvidmode structure corresponds to a function parameter
+or window hint and combine to form the _desired video mode_ for that window.
+The supported video mode most closely matching the desired video mode will be
+set for the chosen monitor as long as the window has input focus. For more
+information about retrieving video modes, see @ref monitor_modes.
+
+Video mode field | Corresponds to
+---------------- | --------------
+GLFWvidmode.width | `width` parameter of @ref glfwCreateWindow
+GLFWvidmode.height | `height` parameter of @ref glfwCreateWindow
+GLFWvidmode.redBits | @ref GLFW_RED_BITS hint
+GLFWvidmode.greenBits | @ref GLFW_GREEN_BITS hint
+GLFWvidmode.blueBits | @ref GLFW_BLUE_BITS hint
+GLFWvidmode.refreshRate | @ref GLFW_REFRESH_RATE hint
+
+Once you have a full screen window, you can change its resolution, refresh rate
+and monitor with @ref glfwSetWindowMonitor. If you only need change its
+resolution you can also call @ref glfwSetWindowSize. In all cases, the new
+video mode will be selected the same way as the video mode chosen by @ref
+glfwCreateWindow. If the window has an OpenGL or OpenGL ES context, it will be
+unaffected.
+
+By default, the original video mode of the monitor will be restored and the
+window iconified if it loses input focus, to allow the user to switch back to
+the desktop. This behavior can be disabled with the
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_hint) window hint, for example if you
+wish to simultaneously cover multiple monitors with full screen windows.
+
+If a monitor is disconnected, all windows that are full screen on that monitor
+will be switched to windowed mode. See @ref monitor_event for more information.
+
+
+@subsubsection window_windowed_full_screen "Windowed full screen" windows
+
+If the closest match for the desired video mode is the current one, the video
+mode will not be changed, making window creation faster and application
+switching much smoother. This is sometimes called _windowed full screen_ or
+_borderless full screen_ window and counts as a full screen window. To create
+such a window, request the current video mode.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwWindowHint(GLFW_RED_BITS, mode->redBits);
+glfwWindowHint(GLFW_GREEN_BITS, mode->greenBits);
+glfwWindowHint(GLFW_BLUE_BITS, mode->blueBits);
+glfwWindowHint(GLFW_REFRESH_RATE, mode->refreshRate);
+
+GLFWwindow* window = glfwCreateWindow(mode->width, mode->height, "My Title", monitor, NULL);
+@endcode
+
+This also works for windowed mode windows that are made full screen.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwSetWindowMonitor(window, monitor, 0, 0, mode->width, mode->height, mode->refreshRate);
+@endcode
+
+Note that @ref glfwGetVideoMode returns the _current_ video mode of a monitor,
+so if you already have a full screen window on that monitor that you want to
+make windowed full screen, you need to have saved the desktop resolution before.
+
+
+@subsection window_destruction Window destruction
+
+When a window is no longer needed, destroy it with @ref glfwDestroyWindow.
+
+@code
+glfwDestroyWindow(window);
+@endcode
+
+Window destruction always succeeds. Before the actual destruction, all
+callbacks are removed so no further events will be delivered for the window.
+All windows remaining when @ref glfwTerminate is called are destroyed as well.
+
+When a full screen window is destroyed, the original video mode of its monitor
+is restored, but the gamma ramp is left untouched.
+
+
+@subsection window_hints Window creation hints
+
+There are a number of hints that can be set before the creation of a window and
+context. Some affect the window itself, others affect the framebuffer or
+context. These hints are set to their default values each time the library is
+initialized with @ref glfwInit. Integer value hints can be set individually
+with @ref glfwWindowHint and string value hints with @ref glfwWindowHintString.
+You can reset all at once to their defaults with @ref glfwDefaultWindowHints.
+
+Some hints are platform specific. These are always valid to set on any
+platform but they will only affect their specific platform. Other platforms
+will ignore them. Setting these hints requires no platform specific headers or
+calls.
+
+@note Window hints need to be set before the creation of the window and context
+you wish to have the specified attributes. They function as additional
+arguments to @ref glfwCreateWindow.
+
+
+@subsubsection window_hints_hard Hard and soft constraints
+
+Some window hints are hard constraints. These must match the available
+capabilities _exactly_ for window and context creation to succeed. Hints
+that are not hard constraints are matched as closely as possible, but the
+resulting context and framebuffer may differ from what these hints requested.
+
+The following hints are always hard constraints:
+- @ref GLFW_STEREO
+- @ref GLFW_DOUBLEBUFFER
+- [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint)
+- [GLFW_CONTEXT_CREATION_API](@ref GLFW_CONTEXT_CREATION_API_hint)
+
+The following additional hints are hard constraints when requesting an OpenGL
+context, but are ignored when requesting an OpenGL ES context:
+- [GLFW_OPENGL_FORWARD_COMPAT](@ref GLFW_OPENGL_FORWARD_COMPAT_hint)
+- [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint)
+
+
+@subsubsection window_hints_wnd Window related hints
+
+@anchor GLFW_RESIZABLE_hint
+__GLFW_RESIZABLE__ specifies whether the windowed mode window will be resizable
+_by the user_. The window will still be resizable using the @ref
+glfwSetWindowSize function. Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+This hint is ignored for full screen and undecorated windows.
+
+@anchor GLFW_VISIBLE_hint
+__GLFW_VISIBLE__ specifies whether the windowed mode window will be initially
+visible. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This hint is
+ignored for full screen windows.
+
+@anchor GLFW_DECORATED_hint
+__GLFW_DECORATED__ specifies whether the windowed mode window will have window
+decorations such as a border, a close widget, etc. An undecorated window will
+not be resizable by the user but will still allow the user to generate close
+events on some platforms. Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+This hint is ignored for full screen windows.
+
+@anchor GLFW_FOCUSED_hint
+__GLFW_FOCUSED__ specifies whether the windowed mode window will be given input
+focus when created. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This
+hint is ignored for full screen and initially hidden windows.
+
+@anchor GLFW_AUTO_ICONIFY_hint
+__GLFW_AUTO_ICONIFY__ specifies whether the full screen window will
+automatically iconify and restore the previous video mode on input focus loss.
+Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This hint is ignored for
+windowed mode windows.
+
+@anchor GLFW_FLOATING_hint
+__GLFW_FLOATING__ specifies whether the windowed mode window will be floating
+above other regular windows, also called topmost or always-on-top. This is
+intended primarily for debugging purposes and cannot be used to implement proper
+full screen windows. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This
+hint is ignored for full screen windows.
+
+@anchor GLFW_MAXIMIZED_hint
+__GLFW_MAXIMIZED__ specifies whether the windowed mode window will be maximized
+when created. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This hint is
+ignored for full screen windows.
+
+@anchor GLFW_CENTER_CURSOR_hint
+__GLFW_CENTER_CURSOR__ specifies whether the cursor should be centered over
+newly created full screen windows. Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`. This hint is ignored for windowed mode windows.
+
+@anchor GLFW_TRANSPARENT_FRAMEBUFFER_hint
+__GLFW_TRANSPARENT_FRAMEBUFFER__ specifies whether the window framebuffer will
+be transparent. If enabled and supported by the system, the window framebuffer
+alpha channel will be used to combine the framebuffer with the background. This
+does not affect window decorations. Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`.
+
+@anchor GLFW_FOCUS_ON_SHOW_hint
+__GLFW_FOCUS_ON_SHOW__ specifies whether the window will be given input
+focus when @ref glfwShowWindow is called. Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`.
+
+@anchor GLFW_SCALE_TO_MONITOR
+__GLFW_SCALE_TO_MONITOR__ specified whether the window content area should be
+resized based on the [monitor content scale](@ref monitor_scale) of any monitor
+it is placed on. This includes the initial placement when the window is
+created. Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+
+This hint only has an effect on platforms where screen coordinates and pixels
+always map 1:1 such as Windows and X11. On platforms like macOS the resolution
+of the framebuffer is changed independently of the window size.
+
+
+@subsubsection window_hints_fb Framebuffer related hints
+
+@anchor GLFW_RED_BITS
+@anchor GLFW_GREEN_BITS
+@anchor GLFW_BLUE_BITS
+@anchor GLFW_ALPHA_BITS
+@anchor GLFW_DEPTH_BITS
+@anchor GLFW_STENCIL_BITS
+__GLFW_RED_BITS__, __GLFW_GREEN_BITS__, __GLFW_BLUE_BITS__, __GLFW_ALPHA_BITS__,
+__GLFW_DEPTH_BITS__ and __GLFW_STENCIL_BITS__ specify the desired bit depths of
+the various components of the default framebuffer. A value of `GLFW_DONT_CARE`
+means the application has no preference.
+
+@anchor GLFW_ACCUM_RED_BITS
+@anchor GLFW_ACCUM_GREEN_BITS
+@anchor GLFW_ACCUM_BLUE_BITS
+@anchor GLFW_ACCUM_ALPHA_BITS
+__GLFW_ACCUM_RED_BITS__, __GLFW_ACCUM_GREEN_BITS__, __GLFW_ACCUM_BLUE_BITS__ and
+__GLFW_ACCUM_ALPHA_BITS__ specify the desired bit depths of the various
+components of the accumulation buffer. A value of `GLFW_DONT_CARE` means the
+application has no preference.
+
+Accumulation buffers are a legacy OpenGL feature and should not be used in new
+code.
+
+@anchor GLFW_AUX_BUFFERS
+__GLFW_AUX_BUFFERS__ specifies the desired number of auxiliary buffers. A value
+of `GLFW_DONT_CARE` means the application has no preference.
+
+Auxiliary buffers are a legacy OpenGL feature and should not be used in new
+code.
+
+@anchor GLFW_STEREO
+__GLFW_STEREO__ specifies whether to use OpenGL stereoscopic rendering.
+Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This is a hard constraint.
+
+@anchor GLFW_SAMPLES
+__GLFW_SAMPLES__ specifies the desired number of samples to use for
+multisampling. Zero disables multisampling. A value of `GLFW_DONT_CARE` means
+the application has no preference.
+
+@anchor GLFW_SRGB_CAPABLE
+__GLFW_SRGB_CAPABLE__ specifies whether the framebuffer should be sRGB capable.
+Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+
+@note __OpenGL:__ If enabled and supported by the system, the
+`GL_FRAMEBUFFER_SRGB` enable will control sRGB rendering. By default, sRGB
+rendering will be disabled.
+
+@note __OpenGL ES:__ If enabled and supported by the system, the context will
+always have sRGB rendering enabled.
+
+@anchor GLFW_DOUBLEBUFFER
+__GLFW_DOUBLEBUFFER__ specifies whether the framebuffer should be double
+buffered. You nearly always want to use double buffering. This is a hard
+constraint. Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+
+
+@subsubsection window_hints_mtr Monitor related hints
+
+@anchor GLFW_REFRESH_RATE
+__GLFW_REFRESH_RATE__ specifies the desired refresh rate for full screen
+windows. A value of `GLFW_DONT_CARE` means the highest available refresh rate
+will be used. This hint is ignored for windowed mode windows.
+
+
+@subsubsection window_hints_ctx Context related hints
+
+@anchor GLFW_CLIENT_API_hint
+__GLFW_CLIENT_API__ specifies which client API to create the context for.
+Possible values are `GLFW_OPENGL_API`, `GLFW_OPENGL_ES_API` and `GLFW_NO_API`.
+This is a hard constraint.
+
+@anchor GLFW_CONTEXT_CREATION_API_hint
+__GLFW_CONTEXT_CREATION_API__ specifies which context creation API to use to
+create the context. Possible values are `GLFW_NATIVE_CONTEXT_API`,
+`GLFW_EGL_CONTEXT_API` and `GLFW_OSMESA_CONTEXT_API`. This is a hard
+constraint. If no client API is requested, this hint is ignored.
+
+An [extension loader library](@ref context_glext_auto) that assumes it knows
+which API was used to create the current context may fail if you change this
+hint. This can be resolved by having it load functions via @ref
+glfwGetProcAddress.
+
+@note @wayland The EGL API _is_ the native context creation API, so this hint
+will have no effect.
+
+@note @x11 On some Linux systems, creating contexts via both the native and EGL
+APIs in a single process will cause the application to segfault. Stick to one
+API or the other on Linux for now.
+
+@note __OSMesa:__ As its name implies, an OpenGL context created with OSMesa
+does not update the window contents when its buffers are swapped. Use OpenGL
+functions or the OSMesa native access functions @ref glfwGetOSMesaColorBuffer
+and @ref glfwGetOSMesaDepthBuffer to retrieve the framebuffer contents.
+
+@anchor GLFW_CONTEXT_VERSION_MAJOR_hint
+@anchor GLFW_CONTEXT_VERSION_MINOR_hint
+__GLFW_CONTEXT_VERSION_MAJOR__ and __GLFW_CONTEXT_VERSION_MINOR__ specify the
+client API version that the created context must be compatible with. The exact
+behavior of these hints depend on the requested client API.
+
+While there is no way to ask the driver for a context of the highest supported
+version, GLFW will attempt to provide this when you ask for a version 1.0
+context, which is the default for these hints.
+
+Do not confuse these hints with @ref GLFW_VERSION_MAJOR and @ref
+GLFW_VERSION_MINOR, which provide the API version of the GLFW header.
+
+@note __OpenGL:__ These hints are not hard constraints, but creation will fail
+if the OpenGL version of the created context is less than the one requested. It
+is therefore perfectly safe to use the default of version 1.0 for legacy code
+and you will still get backwards-compatible contexts of version 3.0 and above
+when available.
+
+@note __OpenGL ES:__ These hints are not hard constraints, but creation will
+fail if the OpenGL ES version of the created context is less than the one
+requested. Additionally, OpenGL ES 1.x cannot be returned if 2.0 or later was
+requested, and vice versa. This is because OpenGL ES 3.x is backward compatible
+with 2.0, but OpenGL ES 2.0 is not backward compatible with 1.x.
+
+@note @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.
+
+@anchor GLFW_OPENGL_FORWARD_COMPAT_hint
+__GLFW_OPENGL_FORWARD_COMPAT__ specifies whether the OpenGL context should be
+forward-compatible, i.e. one where all functionality deprecated in the requested
+version of OpenGL is removed. This must only be used if the requested OpenGL
+version is 3.0 or above. If OpenGL ES is requested, this hint is ignored.
+
+Forward-compatibility is described in detail in the
+[OpenGL Reference Manual](https://www.opengl.org/registry/).
+
+@anchor GLFW_OPENGL_DEBUG_CONTEXT_hint
+__GLFW_OPENGL_DEBUG_CONTEXT__ specifies whether the context should be created
+in debug mode, which may provide additional error and diagnostic reporting
+functionality. Possible values are `GLFW_TRUE` and `GLFW_FALSE`.
+
+Debug contexts for OpenGL and OpenGL ES are described in detail by the
+[GL_KHR_debug](https://www.khronos.org/registry/OpenGL/extensions/KHR/KHR_debug.txt)
+extension.
+
+@anchor GLFW_OPENGL_PROFILE_hint
+__GLFW_OPENGL_PROFILE__ specifies which OpenGL profile to create the context
+for. Possible values are one of `GLFW_OPENGL_CORE_PROFILE` or
+`GLFW_OPENGL_COMPAT_PROFILE`, or `GLFW_OPENGL_ANY_PROFILE` to not request
+a specific profile. If requesting an OpenGL version below 3.2,
+`GLFW_OPENGL_ANY_PROFILE` must be used. If OpenGL ES is requested, this hint
+is ignored.
+
+OpenGL profiles are described in detail in the
+[OpenGL Reference Manual](https://www.opengl.org/registry/).
+
+@anchor GLFW_CONTEXT_ROBUSTNESS_hint
+__GLFW_CONTEXT_ROBUSTNESS__ specifies the robustness strategy to be used by the
+context. This can be one of `GLFW_NO_RESET_NOTIFICATION` or
+`GLFW_LOSE_CONTEXT_ON_RESET`, or `GLFW_NO_ROBUSTNESS` to not request
+a robustness strategy.
+
+@anchor GLFW_CONTEXT_RELEASE_BEHAVIOR_hint
+__GLFW_CONTEXT_RELEASE_BEHAVIOR__ specifies the release behavior to be
+used by the context. Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`,
+`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`. If the
+behavior is `GLFW_ANY_RELEASE_BEHAVIOR`, the default behavior of the context
+creation API will be used. If the behavior is `GLFW_RELEASE_BEHAVIOR_FLUSH`,
+the pipeline will be flushed whenever the context is released from being the
+current one. If the behavior is `GLFW_RELEASE_BEHAVIOR_NONE`, the pipeline will
+not be flushed on release.
+
+Context release behaviors are described in detail by the
+[GL_KHR_context_flush_control](https://www.opengl.org/registry/specs/KHR/context_flush_control.txt)
+extension.
+
+@anchor GLFW_CONTEXT_NO_ERROR_hint
+__GLFW_CONTEXT_NO_ERROR__ specifies whether errors should be generated by the
+context. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. If enabled,
+situations that would have generated errors instead cause undefined behavior.
+
+The no error mode for OpenGL and OpenGL ES is described in detail by the
+[GL_KHR_no_error](https://www.opengl.org/registry/specs/KHR/no_error.txt)
+extension.
+
+
+@subsubsection window_hints_osx macOS specific window hints
+
+@anchor GLFW_COCOA_RETINA_FRAMEBUFFER_hint
+__GLFW_COCOA_RETINA_FRAMEBUFFER__ specifies whether to use full resolution
+framebuffers on Retina displays. Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`. This is ignored on other platforms.
+
+@anchor GLFW_COCOA_FRAME_NAME_hint
+__GLFW_COCOA_FRAME_NAME__ specifies the UTF-8 encoded name to use for autosaving
+the window frame, or if empty disables frame autosaving for the window. This is
+ignored on other platforms. This is set with @ref glfwWindowHintString.
+
+@anchor GLFW_COCOA_GRAPHICS_SWITCHING_hint
+__GLFW_COCOA_GRAPHICS_SWITCHING__ specifies whether to in Automatic Graphics
+Switching, i.e. to allow the system to choose the integrated GPU for the OpenGL
+context and move it between GPUs if necessary or whether to force it to always
+run on the discrete GPU. This only affects systems with both integrated and
+discrete GPUs. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This is
+ignored on other platforms.
+
+Simpler programs and tools may want to enable this to save power, while games
+and other applications performing advanced rendering will want to leave it
+disabled.
+
+A bundled application that wishes to participate in Automatic Graphics Switching
+should also declare this in its `Info.plist` by setting the
+`NSSupportsAutomaticGraphicsSwitching` key to `true`.
+
+
+@subsubsection window_hints_x11 X11 specific window hints
+
+@anchor GLFW_X11_CLASS_NAME_hint
+@anchor GLFW_X11_INSTANCE_NAME_hint
+__GLFW_X11_CLASS_NAME__ and __GLFW_X11_INSTANCE_NAME__ specifies the desired
+ASCII encoded class and instance parts of the ICCCM `WM_CLASS` window property.
+These are set with @ref glfwWindowHintString.
+

+Each window has a user pointer that can be set with @ref
+glfwSetWindowUserPointer and queried with @ref glfwGetWindowUserPointer. This
+can be used for any purpose you need and will not be modified by GLFW throughout
+the life-time of the window.
+
+The initial value of the pointer is `NULL`.
+
+
+@subsection window_close Window closing and close flag
+
+When the user attempts to close the window, for example by clicking the close
+widget or using a key chord like Alt+F4, the _close flag_ of the window is set.
+The window is however not actually destroyed and, unless you watch for this
+state change, nothing further happens.
+
+The current state of the close flag is returned by @ref glfwWindowShouldClose
+and can be set or cleared directly with @ref glfwSetWindowShouldClose. A common
+pattern is to use the close flag as a main loop condition.
+
+@code
+while (!glfwWindowShouldClose(window))
+{
+ render(window);
+
+ glfwSwapBuffers(window);
+ glfwPollEvents();
+}
+@endcode
+
+If you wish to be notified when the user attempts to close a window, set a close
+callback.
+
+@code
+glfwSetWindowCloseCallback(window, window_close_callback);
+@endcode
+
+The callback function is called directly _after_ the close flag has been set.
+It can be used for example to filter close requests and clear the close flag
+again unless certain conditions are met.
+
+@code
+void window_close_callback(GLFWwindow* window)
+{
+ if (!time_to_close)
+ glfwSetWindowShouldClose(window, GLFW_FALSE);
+}
+@endcode
+
+
+@subsection window_size Window size
+
+The size of a window can be changed with @ref glfwSetWindowSize. For windowed
+mode windows, this sets the size, in
+[screen coordinates](@ref coordinate_systems) of the _content area_ or _content
+area_ of the window. The window system may impose limits on window size.
+
+@code
+glfwSetWindowSize(window, 640, 480);
+@endcode
+
+For full screen windows, the specified size becomes the new resolution of the
+window's desired video mode. The video mode most closely matching the new
+desired video mode is set immediately. The window is resized to fit the
+resolution of the set video mode.
+
+If you wish to be notified when a window is resized, whether by the user, the
+system or your own code, set a size callback.
+
+@code
+glfwSetWindowSizeCallback(window, window_size_callback);
+@endcode
+
+The callback function receives the new size, in screen coordinates, of the
+content area of the window when the window is resized.
+
+@code
+void window_size_callback(GLFWwindow* window, int width, int height)
+{
+}
+@endcode
+
+There is also @ref glfwGetWindowSize for directly retrieving the current size of
+a window.
+
+@code
+int width, height;
+glfwGetWindowSize(window, &width, &height);
+@endcode
+
+@note Do not pass the window size to `glViewport` or other pixel-based OpenGL
+calls. The window size is in screen coordinates, not pixels. Use the
+[framebuffer size](@ref window_fbsize), which is in pixels, for pixel-based
+calls.
+
+The above functions work with the size of the content area, but decorated
+windows typically have title bars and window frames around this rectangle. You
+can retrieve the extents of these with @ref glfwGetWindowFrameSize.
+
+@code
+int left, top, right, bottom;
+glfwGetWindowFrameSize(window, &left, &top, &right, &bottom);
+@endcode
+
+The returned values are the distances, in screen coordinates, from the edges of
+the content area to the corresponding edges of the full window. As they are
+distances and not coordinates, they are always zero or positive.
+
+
+@subsection window_fbsize Framebuffer size
+
+While the size of a window is measured in screen coordinates, OpenGL works with
+pixels. The size you pass into `glViewport`, for example, should be in pixels.
+On some machines screen coordinates and pixels are the same, but on others they
+will not be. There is a second set of functions to retrieve the size, in
+pixels, of the framebuffer of a window.
+
+If you wish to be notified when the framebuffer of a window is resized, whether
+by the user or the system, set a size callback.
+
+@code
+glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
+@endcode
+
+The callback function receives the new size of the framebuffer when it is
+resized, which can for example be used to update the OpenGL viewport.
+
+@code
+void framebuffer_size_callback(GLFWwindow* window, int width, int height)
+{
+ glViewport(0, 0, width, height);
+}
+@endcode
+
+There is also @ref glfwGetFramebufferSize for directly retrieving the current
+size of the framebuffer of a window.
+
+@code
+int width, height;
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+The size of a framebuffer may change independently of the size of a window, for
+example if the window is dragged between a regular monitor and a high-DPI one.
+
+
+@subsection window_scale Window content scale
+
+The content scale for a window can be retrieved with @ref
+glfwGetWindowContentScale.
+
+@code
+float xscale, yscale;
+glfwGetWindowContentScale(window, &xscale, &yscale);
+@endcode
+
+The content scale is the ratio between the current DPI and the platform's
+default DPI. This is especially important for text and any UI elements. If the
+pixel dimensions of your UI scaled by this look appropriate on your machine then
+it should appear at a reasonable size on other machines regardless of their DPI
+and scaling settings. This relies on the system DPI and scaling settings being
+somewhat correct.
+
+On systems where each monitors can have its own content scale, the window
+content scale will depend on which monitor the system considers the window to be
+on.
+
+If you wish to be notified when the content scale of a window changes, whether
+because of a system setting change or because it was moved to a monitor with
+a different scale, set a content scale callback.
+
+@code
+glfwSetWindowContentScaleCallback(window, window_content_scale_callback);
+@endcode
+
+The callback function receives the new content scale of the window.
+
+@code
+void window_content_scale_callback(GLFWwindow* window, float xscale, float yscale)
+{
+ set_interface_scale(xscale, yscale);
+}
+@endcode
+
+On platforms where pixels and screen coordinates always map 1:1, the window
+will need to be resized to appear the same size when it is moved to a monitor
+with a different content scale. To have this done automatically both when the
+window is created and when its content scale later changes, set the @ref
+GLFW_SCALE_TO_MONITOR window hint.
+
+
+@subsection window_sizelimits Window size limits
+
+The minimum and maximum size of the content area of a windowed mode window can
+be enforced with @ref glfwSetWindowSizeLimits. The user may resize the window
+to any size and aspect ratio within the specified limits, unless the aspect
+ratio is also set.
+
+@code
+glfwSetWindowSizeLimits(window, 200, 200, 400, 400);
+@endcode
+
+To specify only a minimum size or only a maximum one, set the other pair to
+`GLFW_DONT_CARE`.
+
+@code
+glfwSetWindowSizeLimits(window, 640, 480, GLFW_DONT_CARE, GLFW_DONT_CARE);
+@endcode
+
+To disable size limits for a window, set them all to `GLFW_DONT_CARE`.
+
+The aspect ratio of the content area of a windowed mode window can be enforced
+with @ref glfwSetWindowAspectRatio. The user may resize the window freely
+unless size limits are also set, but the size will be constrained to maintain
+the aspect ratio.
+
+@code
+glfwSetWindowAspectRatio(window, 16, 9);
+@endcode
+
+The aspect ratio is specified as a numerator and denominator, corresponding to
+the width and height, respectively. If you want a window to maintain its
+current aspect ratio, use its current size as the ratio.
+
+@code
+int width, height;
+glfwGetWindowSize(window, &width, &height);
+glfwSetWindowAspectRatio(window, width, height);
+@endcode
+
+To disable the aspect ratio limit for a window, set both terms to
+`GLFW_DONT_CARE`.
+
+You can have both size limits and aspect ratio set for a window, but the results
+are undefined if they conflict.
+
+
+@subsection window_pos Window position
+
+The position of a windowed-mode window can be changed with @ref
+glfwSetWindowPos. This moves the window so that the upper-left corner of its
+content area has the specified [screen coordinates](@ref coordinate_systems).
+The window system may put limitations on window placement.
+
+@code
+glfwSetWindowPos(window, 100, 100);
+@endcode
+
+If you wish to be notified when a window is moved, whether by the user, the
+system or your own code, set a position callback.
+
+@code
+glfwSetWindowPosCallback(window, window_pos_callback);
+@endcode
+
+The callback function receives the new position, in screen coordinates, of the
+upper-left corner of the content area when the window is moved.
+
+@code
+void window_pos_callback(GLFWwindow* window, int xpos, int ypos)
+{
+}
+@endcode
+
+There is also @ref glfwGetWindowPos for directly retrieving the current position
+of the content area of the window.
+
+@code
+int xpos, ypos;
+glfwGetWindowPos(window, &xpos, &ypos);
+@endcode
+
+
+@subsection window_title Window title
+
+All GLFW windows have a title, although undecorated or full screen windows may
+not display it or only display it in a task bar or similar interface. You can
+set a UTF-8 encoded window title with @ref glfwSetWindowTitle.
+
+@code
+glfwSetWindowTitle(window, "My Window");
+@endcode
+
+The specified string is copied before the function returns, so there is no need
+to keep it around.
+
+As long as your source file is encoded as UTF-8, you can use any Unicode
+characters directly in the source.
+
+@code
+glfwSetWindowTitle(window, "ラストエグザイル");
+@endcode
+
+If you are using C++11 or C11, you can use a UTF-8 string literal.
+
+@code
+glfwSetWindowTitle(window, u8"This is always a UTF-8 string");
+@endcode
+
+
+@subsection window_icon Window icon
+
+Decorated windows have icons on some platforms. You can set this icon by
+specifying a list of candidate images with @ref glfwSetWindowIcon.
+
+@code
+GLFWimage images[2];
+images[0] = load_icon("my_icon.png");
+images[1] = load_icon("my_icon_small.png");
+
+glfwSetWindowIcon(window, 2, images);
+@endcode
+
+The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits
+per channel with the red channel first. The pixels are arranged canonically as
+sequential rows, starting from the top-left corner.
+
+To revert to the default window icon, pass in an empty image array.
+
+@code
+glfwSetWindowIcon(window, 0, NULL);
+@endcode
+
+
+@subsection window_monitor Window monitor
+
+Full screen windows are associated with a specific monitor. You can get the
+handle for this monitor with @ref glfwGetWindowMonitor.
+
+@code
+GLFWmonitor* monitor = glfwGetWindowMonitor(window);
+@endcode
+
+This monitor handle is one of those returned by @ref glfwGetMonitors.
+
+For windowed mode windows, this function returns `NULL`. This is how to tell
+full screen windows from windowed mode windows.
+
+You can move windows between monitors or between full screen and windowed mode
+with @ref glfwSetWindowMonitor. When making a window full screen on the same or
+on a different monitor, specify the desired monitor, resolution and refresh
+rate. The position arguments are ignored.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwSetWindowMonitor(window, monitor, 0, 0, mode->width, mode->height, mode->refreshRate);
+@endcode
+
+When making the window windowed, specify the desired position and size. The
+refresh rate argument is ignored.
+
+@code
+glfwSetWindowMonitor(window, NULL, xpos, ypos, width, height, 0);
+@endcode
+
+This restores any previous window settings such as whether it is decorated,
+floating, resizable, has size or aspect ratio limits, etc.. To restore a window
+that was originally windowed to its original size and position, save these
+before making it full screen and then pass them in as above.
+
+
+@subsection window_iconify Window iconification
+
+Windows can be iconified (i.e. minimized) with @ref glfwIconifyWindow.
+
+@code
+glfwIconifyWindow(window);
+@endcode
+
+When a full screen window is iconified, the original video mode of its monitor
+is restored until the user or application restores the window.
+
+Iconified windows can be restored with @ref glfwRestoreWindow. This function
+also restores windows from maximization.
+
+@code
+glfwRestoreWindow(window);
+@endcode
+
+When a full screen window is restored, the desired video mode is restored to its
+monitor as well.
+
+If you wish to be notified when a window is iconified or restored, whether by
+the user, system or your own code, set an iconify callback.
+
+@code
+glfwSetWindowIconifyCallback(window, window_iconify_callback);
+@endcode
+
+The callback function receives changes in the iconification state of the window.
+
+@code
+void window_iconify_callback(GLFWwindow* window, int iconified)
+{
+ if (iconified)
+ {
+ // The window was iconified
+ }
+ else
+ {
+ // The window was restored
+ }
+}
+@endcode
+
+You can also get the current iconification state with @ref glfwGetWindowAttrib.
+
+@code
+int iconified = glfwGetWindowAttrib(window, GLFW_ICONIFIED);
+@endcode
+
+
+@subsection window_maximize Window maximization
+
+Windows can be maximized (i.e. zoomed) with @ref glfwMaximizeWindow.
+
+@code
+glfwMaximizeWindow(window);
+@endcode
+
+Full screen windows cannot be maximized and passing a full screen window to this
+function does nothing.
+
+Maximized windows can be restored with @ref glfwRestoreWindow. This function
+also restores windows from iconification.
+
+@code
+glfwRestoreWindow(window);
+@endcode
+
+If you wish to be notified when a window is maximized or restored, whether by
+the user, system or your own code, set a maximize callback.
+
+@code
+glfwSetWindowMaximizeCallback(window, window_maximize_callback);
+@endcode
+
+The callback function receives changes in the maximization state of the window.
+
+@code
+void window_maximize_callback(GLFWwindow* window, int maximized)
+{
+ if (maximized)
+ {
+ // The window was maximized
+ }
+ else
+ {
+ // The window was restored
+ }
+}
+@endcode
+
+You can also get the current maximization state with @ref glfwGetWindowAttrib.
+
+@code
+int maximized = glfwGetWindowAttrib(window, GLFW_MAXIMIZED);
+@endcode
+
+By default, newly created windows are not maximized. You can change this
+behavior by setting the [GLFW_MAXIMIZED](@ref GLFW_MAXIMIZED_hint) window hint
+before creating the window.
+
+@code
+glfwWindowHint(GLFW_MAXIMIZED, GLFW_TRUE);
+@endcode
+
+
+@subsection window_hide Window visibility
+
+Windowed mode windows can be hidden with @ref glfwHideWindow.
+
+@code
+glfwHideWindow(window);
+@endcode
+
+This makes the window completely invisible to the user, including removing it
+from the task bar, dock or window list. Full screen windows cannot be hidden
+and calling @ref glfwHideWindow on a full screen window does nothing.
+
+Hidden windows can be shown with @ref glfwShowWindow.
+
+@code
+glfwShowWindow(window);
+@endcode
+
+By default, this function will also set the input focus to that window. Set
+the [GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_hint) window hint to change
+this behavior for all newly created windows, or change the behavior for an
+existing window with @ref glfwSetWindowAttrib.
+
+You can also get the current visibility state with @ref glfwGetWindowAttrib.
+
+@code
+int visible = glfwGetWindowAttrib(window, GLFW_VISIBLE);
+@endcode
+
+By default, newly created windows are visible. You can change this behavior by
+setting the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint before creating
+the window.
+
+@code
+glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
+@endcode
+
+Windows created hidden are completely invisible to the user until shown. This
+can be useful if you need to set up your window further before showing it, for
+example moving it to a specific location.
+
+
+@subsection window_focus Window input focus
+
+Windows can be given input focus and brought to the front with @ref
+glfwFocusWindow.
+
+@code
+glfwFocusWindow(window);
+@endcode
+
+Keep in mind that it can be very disruptive to the user when a window is forced
+to the top. For a less disruptive way of getting the user's attention, see
+[attention requests](@ref window_attention).
+
+If you wish to be notified when a window gains or loses input focus, whether by
+the user, system or your own code, set a focus callback.
+
+@code
+glfwSetWindowFocusCallback(window, window_focus_callback);
+@endcode
+
+The callback function receives changes in the input focus state of the window.
+
+@code
+void window_focus_callback(GLFWwindow* window, int focused)
+{
+ if (focused)
+ {
+ // The window gained input focus
+ }
+ else
+ {
+ // The window lost input focus
+ }
+}
+@endcode
+
+You can also get the current input focus state with @ref glfwGetWindowAttrib.
+
+@code
+int focused = glfwGetWindowAttrib(window, GLFW_FOCUSED);
+@endcode
+
+By default, newly created windows are given input focus. You can change this
+behavior by setting the [GLFW_FOCUSED](@ref GLFW_FOCUSED_hint) window hint
+before creating the window.
+
+@code
+glfwWindowHint(GLFW_FOCUSED, GLFW_FALSE);
+@endcode
+
+
+@subsection window_attention Window attention request
+
+If you wish to notify the user of an event without interrupting, you can request
+attention with @ref glfwRequestWindowAttention.
+
+@code
+glfwRequestWindowAttention(window);
+@endcode
+
+The system will highlight the specified window, or on platforms where this is
+not supported, the application as a whole. Once the user has given it
+attention, the system will automatically end the request.
+
+
+@subsection window_refresh Window damage and refresh
+
+If you wish to be notified when the contents of a window is damaged and needs
+to be refreshed, set a window refresh callback.
+
+@code
+glfwSetWindowRefreshCallback(m_handle, window_refresh_callback);
+@endcode
+
+The callback function is called when the contents of the window needs to be
+refreshed.
+
+@code
+void window_refresh_callback(GLFWwindow* window)
+{
+ draw_editor_ui(window);
+ glfwSwapBuffers(window);
+}
+@endcode
+
+@note On compositing window systems such as Aero, Compiz or Aqua, where the
+window contents are saved off-screen, this callback might only be called when
+the window or framebuffer is resized.
+
+
+@subsection window_transparency Window transparency
+
+GLFW supports two kinds of transparency for windows; framebuffer transparency
+and whole window transparency. A single window may not use both methods. The
+results of doing this are undefined.
+
+Both methods require the platform to support it and not every version of every
+platform GLFW supports does this, so there are mechanisms to check whether the
+window really is transparent.
+
+Window framebuffers can be made transparent on a per-pixel per-frame basis with
+the [GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint)
+window hint.
+
+@code
+glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE);
+@endcode
+
+If supported by the system, the window content area will be composited with the
+background using the framebuffer per-pixel alpha channel. This requires desktop
+compositing to be enabled on the system. It does not affect window decorations.
+
+You can check whether the window framebuffer was successfully made transparent
+with the
+[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_attrib)
+window attribute.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_TRANSPARENT_FRAMEBUFFER))
+{
+ // window framebuffer is currently transparent
+}
+@endcode
+
+GLFW comes with an example that enabled framebuffer transparency called `gears`.
+
+The opacity of the whole window, including any decorations, can be set with @ref
+glfwSetWindowOpacity.
+
+@code
+glfwSetWindowOpacity(window, 0.5f);
+@endcode
+
+The opacity (or alpha) value is a positive finite number between zero and one,
+where 0 (zero) is fully transparent and 1 (one) is fully opaque. The initial
+opacity value for newly created windows is 1.
+
+The current opacity of a window can be queried with @ref glfwGetWindowOpacity.
+
+@code
+float opacity = glfwGetWindowOpacity(window);
+@endcode
+
+If the system does not support whole window transparency, this function always
+returns one.
+
+GLFW comes with a test program that lets you control whole window transparency
+at run-time called `opacity`.
+
+
+@subsection window_attribs Window attributes
+
+Windows have a number of attributes that can be returned using @ref
+glfwGetWindowAttrib. Some reflect state that may change as a result of user
+interaction, (e.g. whether it has input focus), while others reflect inherent
+properties of the window (e.g. what kind of border it has). Some are related to
+the window and others to its OpenGL or OpenGL ES context.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_FOCUSED))
+{
+ // window has input focus
+}
+@endcode
+
+The [GLFW_DECORATED](@ref GLFW_DECORATED_attrib),
+[GLFW_RESIZABLE](@ref GLFW_RESIZABLE_attrib),
+[GLFW_FLOATING](@ref GLFW_FLOATING_attrib),
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_attrib) and
+[GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_attrib) window attributes can be
+changed with @ref glfwSetWindowAttrib.
+
+@code
+glfwSetWindowAttrib(window, GLFW_RESIZABLE, GLFW_FALSE);
+@endcode
+
+
+

+after with @ref glfwSetWindowAttrib.
+
+@subsubsection window_attribs_ctx Context related attributes
+
+@anchor GLFW_CLIENT_API_attrib
+__GLFW_CLIENT_API__ indicates the client API provided by the window's context;
+either `GLFW_OPENGL_API`, `GLFW_OPENGL_ES_API` or `GLFW_NO_API`.
+
+@anchor GLFW_CONTEXT_CREATION_API_attrib
+__GLFW_CONTEXT_CREATION_API__ indicates the context creation API used to create
+the window's context; either `GLFW_NATIVE_CONTEXT_API`, `GLFW_EGL_CONTEXT_API`
+or `GLFW_OSMESA_CONTEXT_API`.
+

+@anchor GLFW_CONTEXT_VERSION_MINOR_attrib
+@anchor GLFW_CONTEXT_REVISION_attrib
+__GLFW_CONTEXT_VERSION_MAJOR__, __GLFW_CONTEXT_VERSION_MINOR__ and
+__GLFW_CONTEXT_REVISION__ indicate the client API version of the window's

+
+@note Do not confuse these attributes with `GLFW_VERSION_MAJOR`,
+`GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` which provide the API version
+of the GLFW header.
+
+@anchor GLFW_OPENGL_FORWARD_COMPAT_attrib
+__GLFW_OPENGL_FORWARD_COMPAT__ is `GLFW_TRUE` if the window's context is an
+OpenGL forward-compatible one, or `GLFW_FALSE` otherwise.
+

+mode, or `GLFW_FALSE` otherwise.
+
+@anchor GLFW_OPENGL_PROFILE_attrib
+__GLFW_OPENGL_PROFILE__ indicates the OpenGL profile used by the context. This
+is `GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context
+uses a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is
+unknown or the context is an OpenGL ES context. Note that the returned profile
+may not match the profile bits of the context flags, as GLFW will try other
+means of detecting the profile when no bits are set.
+
+@anchor GLFW_CONTEXT_RELEASE_BEHAVIOR_attrib
+__GLFW_CONTEXT_RELEASE_BEHAVIOR__ indicates the release used by the context.
+Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`,
+`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`. If the
+behavior is `GLFW_ANY_RELEASE_BEHAVIOR`, the default behavior of the context
+creation API will be used. If the behavior is `GLFW_RELEASE_BEHAVIOR_FLUSH`,
+the pipeline will be flushed whenever the context is released from being the
+current one. If the behavior is `GLFW_RELEASE_BEHAVIOR_NONE`, the pipeline will
+not be flushed on release.
+
+@anchor GLFW_CONTEXT_NO_ERROR_attrib
+__GLFW_CONTEXT_NO_ERROR__ indicates whether errors are generated by the context.
+Possible values are `GLFW_TRUE` and `GLFW_FALSE`. If enabled, situations that
+would have generated errors instead cause undefined behavior.
+
+@anchor GLFW_CONTEXT_ROBUSTNESS_attrib
+__GLFW_CONTEXT_ROBUSTNESS__ indicates the robustness strategy used by the
+context. This is `GLFW_LOSE_CONTEXT_ON_RESET` or `GLFW_NO_RESET_NOTIFICATION`
+if the window's context supports robustness, or `GLFW_NO_ROBUSTNESS` otherwise.
+
+
+@subsubsection window_attribs_fb Framebuffer related attributes
+
+GLFW does not expose attributes of the default framebuffer (i.e. the framebuffer
+attached to the window) as these can be queried directly with either OpenGL,
+OpenGL ES or Vulkan.
+
+If you are using version 3.0 or later of OpenGL or OpenGL ES, the
+`glGetFramebufferAttachmentParameteriv` function can be used to retrieve the
+number of bits for the red, green, blue, alpha, depth and stencil buffer
+channels. Otherwise, the `glGetIntegerv` function can be used.
+
+The number of MSAA samples are always retrieved with `glGetIntegerv`. For
+contexts supporting framebuffer objects, the number of samples of the currently
+bound framebuffer is returned.
+
+Attribute | glGetIntegerv | glGetFramebufferAttachmentParameteriv
+------------ | ----------------- | -------------------------------------
+Red bits | `GL_RED_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_RED_SIZE`
+Green bits | `GL_GREEN_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_GREEN_SIZE`
+Blue bits | `GL_BLUE_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_BLUE_SIZE`
+Alpha bits | `GL_ALPHA_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_ALPHA_SIZE`
+Depth bits | `GL_DEPTH_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_DEPTH_SIZE`
+Stencil bits | `GL_STENCIL_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_STENCIL_SIZE`
+MSAA samples | `GL_SAMPLES` | _Not provided by this function_
+
+When calling `glGetFramebufferAttachmentParameteriv`, the red, green, blue and
+alpha sizes are queried from the `GL_BACK_LEFT`, while the depth and stencil
+sizes are queried from the `GL_DEPTH` and `GL_STENCIL` attachments,
+respectively.
+
+
+@section buffer_swap Buffer swapping
+
+GLFW windows are by default double buffered. That means that you have two
+rendering buffers; a front buffer and a back buffer. The front buffer is
+the one being displayed and the back buffer the one you render to.
+
+When the entire frame has been rendered, it is time to swap the back and the
+front buffers in order to display what has been rendered and begin rendering
+a new frame. This is done with @ref glfwSwapBuffers.
+
+@code
+glfwSwapBuffers(window);
+@endcode
+
+Sometimes it can be useful to select when the buffer swap will occur. With the
+function @ref glfwSwapInterval it is possible to select the minimum number of
+monitor refreshes the driver should wait from the time @ref glfwSwapBuffers was
+called before swapping the buffers:
+
+@code
+glfwSwapInterval(1);
+@endcode
+
+If the interval is zero, the swap will take place immediately when @ref
+glfwSwapBuffers is called without waiting for a refresh. Otherwise at least
+interval retraces will pass between each buffer swap. Using a swap interval of
+zero can be useful for benchmarking purposes, when it is not desirable to
+measure the time it takes to wait for the vertical retrace. However, a swap
+interval of one lets you avoid tearing.
+
+Note that this may not work on all machines, as some drivers have
+user-controlled settings that override any swap interval the application
+requests.
+
+A context that supports either the `WGL_EXT_swap_control_tear` or the
+`GLX_EXT_swap_control_tear` extension also accepts _negative_ swap intervals,
+which allows the driver to swap immediately even if a frame arrives a little bit
+late. This trades the risk of visible tears for greater framerate stability.
+You can check for these extensions with @ref glfwExtensionSupported.
