*
|
|
* 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 [window hints](@ref window_hints).
|
|
*
|
|
* Successful creation does not change which context is current. Before you
|
|
* can use the newly created context, you need to
|
|
* [make it current](@ref context_current). For information about the `share`
|
|
* 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. If the window has an
|
|
* OpenGL or OpenGL ES context, it will be unaffected.
|
|
*
|
|
* 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
|
|
* 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

|
|
*
|
|
* The [swap interval](@ref buffer_swap) is not set during window creation and
|
|
* the initial value may vary depending on driver settings and defaults.
|

|
|
