callback

Client hook for special key releases.

This function provides a way to detect the release of a keyboard

key.

The keys are reported exactly as with glutSpecialFunc(), save that the

callback

registered via this function is used to report the event.

This callback is bound to the

current window
.

Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.
