glutTimerFunc(3GLUT) GLUT glutTimerFunc(3GLUT)

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

SYNTAX
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 param-
eter 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 simultaneously.

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 expira-
tion 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.
