The new keyboard callback function.
</dd></dl></div></div><div class="refsect1" lang="en"><a name="glutKeyboardFunc.3GLUT-description"/><h2>Description</h2><p>
<tt>glutKeyboardFunc</tt> sets the keyboard callback for the current window. When a user types into the
window, each key press generating an ASCII character will generate a keyboard 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 <tt>NULL</tt> to
<tt>glutKeyboardFunc</tt> disables the generation of keyboard callbacks.
</p><p>
During a keyboard callback, <a href="glutGetModifiers.3GLUT.xml"><tt>glutGetModifiers</tt></a> may be called to determine the
state of modifier keys when the keystroke generating the callback occurred.
</p><p>
Use <a href="glutSpecialFunc.3GLUT.xml"><tt>glutSpecialFunc</tt></a> for a means to detect non-ASCII key strokes.
