33
35 struct waffle_window
36 An opaque type.
37
38 waffle_window_create()
39 Create a window with the properties specified by config.
40
41 If the platform allows, the window is not displayed onto the screen
42 after creation. To display the window, call waffle_window_show().
43
44 waffle_window_create2()
45 Feature test macro: WAFFLE_API_VERSION >= 0x0106. (See
46 waffle_feature_test_macros(7)).
47
48 Create a window with the properties specified by config and
49 attrib_list. attrib_list must specify the window size either with
50 the attributes WAFFLE_WINDOW_WIDTH and WAFFLE_WINDOW_HEIGHT having
51 positive values <= INT32_MAX, or with the attribute
52 WAFFLE_WINDOW_FULLSCREEN equal to true(1).
53
54 waffle_window_destroy()
55 Destroy the window and release its memory.
56
57 waffle_window_show()
58 Show the window on the display. If the window is already shown, or
59 if the native platform does not support showing windows (such as
60 GBM), then do nothing and returns true.
61
62 waffle_window_swap_buffers()
63 If the window is double-buffered, then implicitly call glFlush()
64 and post the contents of the back buffer to the front buffer. If
65 the window is front-buffered, then do nothing. For
66 platform-specific details of swap semantics, see the specification
67 for the relevant native platform: the GLX 1.4 Specification[1], the
68 EGL 1.4 Specification[2], or the CGL Reference[3].
69
70 waffle_window_get_native()
71 Get the window's underlying native objects. Use free(3) to
72 deallocate the returned pointer. See waffle_native(3) for the
73 definition of union waffle_native_window.
74
76 Functions whose return type is bool return true on success and false on
77 failure. Functions whose return type is a pointer return NULL on
78 failure. Use waffle_error_get_info(3) to get information about any
79 errors.
80
82 See waffle_error(3) for the complete list of waffle's error codes.
83
84 No errors are specific to the waffle_window functions.
