glutPostRedisplay(3GLUT)                            GLUT                            glutPostRedisplay(3GLUT)



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

SYNTAX
       #include <GLUT/glut.h>

       void glutPostRedisplay(void);
       void glutPostWindowRedisplay(int win);

DESCRIPTION
       glutPostRedisplay marks the normal plane of current window as needing to be  redisplayed.   glutPost-WindowRedisplay glutPostWindowRedisplay
       WindowRedisplay 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  win-dow's window's
       dow'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  dis-play display
       play 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.
