DESCRIPTION

       struct waffle_window
           An opaque type.

       waffle_window_create()
           Create a window with the properties specified by config.

           If the platform allows, the window is not displayed onto the screen after creation. To
           display the window, call waffle_window_show().

       waffle_window_create2()
           Feature test macro: WAFFLE_API_VERSION >= 0x0106. (See waffle_feature_test_macros(7)).

           Create a window with the properties specified by config and attrib_list.  attrib_list
           must specify the window size either with the attributes WAFFLE_WINDOW_WIDTH and
           WAFFLE_WINDOW_HEIGHT having positive values <= INT32_MAX, or with the attribute
           WAFFLE_WINDOW_FULLSCREEN equal to true(1).

       waffle_window_destroy()
           Destroy the window and release its memory.

       waffle_window_show()
           Show the window on the display. If the window is already shown, or if the native
           platform does not support showing windows (such as GBM), then do nothing and returns
           true.

       waffle_window_swap_buffers()
           If the window is double-buffered, then implicitly call glFlush() and post the contents
           of the back buffer to the front buffer. If the window is front-buffered, then do
           nothing. For platform-specific details of swap semantics, see the specification for
           the relevant native platform: the GLX 1.4 Specification[1], the EGL 1.4
           Specification[2], or the CGL Reference[3].

       waffle_window_get_native()
           Get the window's underlying native objects. Use free(3) to deallocate the returned
           pointer. See waffle_native(3) for the definition of union waffle_native_window.

RETURN VALUE

       Functions whose return type is bool return true on success and false on failure. Functions
       whose return type is a pointer return NULL on failure. Use waffle_error_get_info(3) to get
       information about any errors.

ERRORS

       See waffle_error(3) for the complete list of waffle's error codes.

       No errors are specific to the waffle_window functions.
