* This function initializes the GLFW library. Before most GLFW functions can

* should be terminated in order to free any resources allocated during or
* after initialization.
*
* If this function fails, it calls @ref glfwTerminate before returning. If it
* succeeds, you should call @ref glfwTerminate before the application exits.
*
* Additional calls to this function after successful initialization but before
* termination will return `GLFW_TRUE` immediately.
*
* The @ref GLFW_PLATFORM init hint controls which platforms are considered during
* initialization. This also depends on which platforms the library was compiled to
* support.
*
* @return `GLFW_TRUE` if successful, or `GLFW_FALSE` if an

* @remark __macOS:__ This function will change the current directory of the
* application to the `Contents/Resources` subdirectory of the application's
* bundle, if present. This can be disabled with the @ref
* GLFW_COCOA_CHDIR_RESOURCES init hint.
*
* @remark __macOS:__ This function will create the main menu and dock icon for the
* application. If GLFW finds a `MainMenu.nib` 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. The menu bar
* and dock icon can be disabled entirely with the @ref GLFW_COCOA_MENUBAR init
* hint.
*
* @remark __Wayland, X11:__ If the library was compiled with support for both
* Wayland and X11, and the @ref GLFW_PLATFORM init hint is set to
* `GLFW_ANY_PLATFORM`, the `XDG_SESSION_TYPE` environment variable affects
* which platform is picked. If the environment variable is not set, or is set
* to something other than `wayland` or `x11`, the regular detection mechanism
* will be used instead.
*
* @remark __X11:__ This function will set the `LC_CTYPE` category of the

* 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.

* 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
