<p>This function creates a window and its associated OpenGL or OpenGL ES context. Most of the options controlling how the window and its context should be created are specified with <aclass="el"href="window_guide.html#window_hints">window hints</a>.</p>
<p>Successful creation does not change which context is current. Before you can use the newly created context, you need to <aclass="el"href="context_guide.html#context_current">make it current</a>. For information about the <code>share</code> parameter, see <aclass="el"href="context_guide.html#context_sharing">Context object sharing</a>.</p>
<p>The created window, framebuffer and context may differ from what you requested, as not all parameters and hints are <aclass="el"href="window_guide.html#window_hints_hard">hard constraints</a>. 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 <aclass="el"href="group__window.html#gacccb29947ea4b16860ebef42c2cb9337">glfwGetWindowAttrib</a>, <aclass="el"href="group__window.html#gaeea7cbc03373a41fb51cfbf9f2a5d4c6">glfwGetWindowSize</a> and <aclass="el"href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a>.</p>
<p>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 <aclass="el"href="monitor_guide.html#monitor_monitors">Retrieving monitors</a>.</p>
<p>For full screen windows, the specified size becomes the resolution of the window's <em>desired video mode</em>. 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 <em>windowed full screen</em> or <em>borderless full screen</em> windows, see <aclass="el"href="window_guide.html#window_windowed_full_screen">"Windowed full screen" windows</a>.</p>
<p>Once you have created the window, you can switch it between windowed and full screen mode with <aclass="el"href="group__window.html#ga81c76c418af80a1cce7055bccb0ae0a7">glfwSetWindowMonitor</a>. This will not affect its OpenGL or OpenGL ES context.</p>
<p>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 <aclass="el"href="window_guide.html#GLFW_VISIBLE_hint">GLFW_VISIBLE</a> window hint, set its <aclass="el"href="window_guide.html#window_pos">position</a> and then <aclass="el"href="window_guide.html#window_hide">show</a> it.</p>
<p>As long as at least one full screen window is not iconified, the screensaver is prohibited from starting.</p>
<p>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 <aclass="el"href="window_guide.html#window_size">size</a> after creation.</p>
<p>The <aclass="el"href="window_guide.html#buffer_swap">swap interval</a> is not set during window creation and the initial value may vary depending on driver settings and defaults.</p>

<b>macOS:</b> 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 <aclass="el"href="window_guide.html#GLFW_OPENGL_FORWARD_COMPAT_hint">GLFW_OPENGL_FORWARD_COMPAT</a> and <aclass="el"href="window_guide.html#GLFW_OPENGL_PROFILE_hint">GLFW_OPENGL_PROFILE</a> hints accordingly.

<dd>
<b>macOS:</b> 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.

<dd>
<b>macOS:</b> The first time a window is created the menu bar is created. If GLFW finds a <code>MainMenu.nib</code> 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 <aclass="el"href="group__init.html#ga71e0b4ce2f2696a84a9b8c5e12dc70cf">GLFW_COCOA_MENUBAR</a> init hint.</dd>

For more information, see <ahref="https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Explained/Explained.html">High Resolution Guidelines for OS X</a> in the Mac Developer Library. The GLFW test and example programs use a custom <code>Info.plist</code> template for this, which can be found as <code>CMake/MacOSXBundleInfo.plist.in</code> in the source tree.</dd>

<b>X11:</b> Some window managers will not respect the placement of initially hidden windows.</dd>

<b>Wayland:</b> 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.</dd>

<p>Since not all events are associated with callbacks, this function may return without a callback having been called even if you are monitoring all callbacks.</p>
<p>On some platforms, a window move, resize or menu operation will cause event processing to block. This is due to how event processing is designed on those platforms. You can use the <aclass="el"href="window_guide.html#window_refresh">window refresh callback</a> to redraw the contents of your window when necessary during such operations.</p>
<p>Do not assume that callbacks you set will <em>only</em> be called in response to event processing functions like this one. While it is necessary to poll for events, window systems that require GLFW to register callbacks of its own can pass events to GLFW in response to many window system function calls. GLFW will pass those events on to the application callbacks before returning.</p>
<p>Event processing is not required for joystick input to work.</p>

<p>This function swaps the front and back buffers of the specified window when rendering with OpenGL or OpenGL ES. If the swap interval is greater than zero, the GPU driver waits the specified number of screen updates before swapping the buffers.</p>
<p>The specified window must have an OpenGL or OpenGL ES context. Specifying a window without a context will generate a <aclass="el"href="group__errors.html#gacff24d2757da752ae4c80bf452356487">GLFW_NO_WINDOW_CONTEXT</a> error.</p>
<p>This function does not apply to Vulkan. If you are rendering with Vulkan, see <code>vkQueuePresentKHR</code> instead.</p>
