NAME

     glutPostWindowRedisplay -- Mark an indicated window as needing a redisplay.

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     void
     glutPostWindowRedisplay(int windowID);

PARAMETERS

      windowID	   The OpenGLUT window id to be affected.

DESCRIPTION

     Similar to glutPostRedisplay(), except that instead of affecting the  current window  , this function affects an arbitrary window, indicated
     by the  windowID  parameter.

NAME

     glutCreateWindow -- Create a new top-level window

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     int
     glutCreateWindow(const char* title);

PARAMETERS

      title	  Title for created window

DESCRIPTION

     This function sends a request for a window to be constructed.  OpenGLUT immediately constructs a data structure to track further events with
     the window, on the theory that eventually the window manager will get back to us with a real window.  This allows us to begin registering
     callbacks immediately.

     In fact, you  must   register a display callback via glutDisplayFunc() before you enter glutMainLoop().

     For onscreen windows, you should not depend upon the window concretely existing or being visibile until you are told that it exists and is
     visible via a registered callback.

     The return value is an  int.    It should be positive for valid windows or 0 if failure occurred for some reason (Though traditional GLUT
     tends to bail out and abort rather than returning errors.)  The integer is your  window id  .  Old GLUT promises that these integers are
     ``small''; we do not reuse old  id  s, but do produce them sequentially.

     You can change the title later via glutSetWindowTitle().
