glutPostRedisplay(3GLUT) GLUT glutPostRedisplay(3GLUT)

NAME
glutPostRedisplay - marks the current window as needing to
be redisplayed.

SYNTAX
void glutPostRedisplay(void);

DESCRIPTION
Mark the normal plane of current window as needing to be
redisplayed. 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, glutPostRe-
display will not set to true the normal plane’s damaged
status (returned by glutLayerGet(GLUT_NORMAL_DAMAGED).
