NAME

       glutTimerFunc - registers a timer callback to be triggered in a specified number of milliseconds.

SYNTAX

       #include <GLUT/glut.h>

       void glutTimerFunc(unsigned int msecs,
		    void (*func)(int value), value);

ARGUMENTS

       msecs	 Number of milliseconds to pass before calling the callback.

       func	 The timer callback function.

       value	 Integer value to pass to the timer callback.

DESCRIPTION

       glutTimerFunc  registers  the timer callback func to be triggered in at least msecs milliseconds. The value parameter to the timer callback
       will be the value of the value parameter to glutTimerFunc. Multiple timer callbacks at same or differing times may be registered simultane-
       ously.

       The  number  of	milliseconds is a lower bound on the time before the callback is generated. GLUT attempts to deliver the timer callback as
       soon as possible after the expiration of the callback's time interval.

       There is no support for canceling a registered callback. Instead, ignore a callback based on its value parameter when it is triggered.

NAME

       glutReshapeFunc - sets the reshape callback for the current window.

SYNTAX

       #include <GLUT/glut.h>

       void glutReshapeFunc(void (*func)(int width, int height));

ARGUMENTS

       func	 The new reshape callback function.

DESCRIPTION

       glutReshapeFunc	sets  the  reshape callback for the current window. The reshape callback is triggered when a window is reshaped. A reshape
       callback is also triggered immediately before a window's first display callback after a window is created or whenever an  overlay  for  the
       window is established. The width and height parameters of the callback specify the new window size in pixels. Before the callback, the cur-
       rent window is set to the window that has been reshaped.

       If a reshape callback is not registered for a window or NULL is passed to glutReshapeFunc (to deregister a previously registered callback),
       the  default  reshape callback is used. This default callback will simply call glViewport(0,0,width,height) on the normal plane (and on the
       overlay if one exists).

       If an overlay is established for the window, a single reshape callback is generated. It is the callback's responsibility to update both the
       normal plane and overlay for the window (changing the layer in use as necessary).

       When  a top-level window is reshaped, subwindows are not reshaped. It is up to the GLUT program to manage the size and positions of subwin-
       dows within a top-level window. Still, reshape callbacks will be triggered for subwindows when their size is changed using  glutReshapeWin-
       dow.
