The new keyboard up callback function.

Description
glutKeyboardFunc
sets the keyboard up (key release) callback for the current
window. When a user types into the window, each key release matching an ASCII character will generate a keyboard up
callback. The key callback parameter is the generated ASCII character. The state of modifier keys such as Shift cannot
be determined directly; their only effect will be on the returned ASCII data. The x and y callback parameters indicate
the mouse location in window relative coordinates when the key was pressed. When a new window is created, no keyboard
callback is initially registered, and ASCII key strokes in the window are ignored. Passing
NULL
to
glutKeyboardFunc
disables the generation of keyboard callbacks.
During a keyboard up callback,
glutGetModifiers
may be called to determine the
state of modifier keys when the keystroke generating the callback occurred.
To avoid the reporting of key release/press pairs due to auto repeat, use
glutIgnoreKeyRepeat
to ignore auto repeated keystrokes.
There is no guarantee that the keyboard press callback will match the exact ASCII character as the keyboard up
callback. For example, the key down may be for a lowercase b, but the key release may report an uppercase B if the
shift state has changed. The same applies to symbols and control characters. The precise behavior is window system
dependent.
Use
glutSpecialUpFunc
for a means to detect non-ASCII key releases.
