- .SH NAME
- glutPostRedisplay, glutPostWindowRedisplay - marks the current or specified window as needing to be
- redisplayed.

- void glutPostRedisplay(void);

- .SH DESCRIPTION
- glutPostRedisplay marks the normal plane of current window as needing to be redisplayed.
- glutPostWindowRedisplay works the specified window as needing to be redisplayed.
- After either call, the next iteration through glutMainLoop, the window's display
- callback will be called to redisplay the window's normal plane. Multiple
- calls to glutPostRedisplay before the next display callback
- opportunity generates only a single redisplay callback.
- glutPostRedisplay may be called within a window's display or
- overlay display callback to re-mark that window for redisplay.
-
- Logically, normal plane damage notification for a window is treated as a
- glutPostRedisplay on the damaged window. Unlike damage
- reported by the window system, glutPostRedisplay will not set to
- true the normal plane's damaged status (returned by
- glutLayerGet(GLUT_NORMAL_DAMAGED).
-
- If the window you want to post a redisplay on is not already current
- (and you do not require it to be immediately made current), using
- glutPostWindowRedisplay is more efficient that calling glutSetWindow to
- the desired window and then calling glutPostRedisplay.
