			KeybdEventCallback |
			This is the signature of the callback function of <f KeybdDriverInitialize>.

@parm	UINT32			| VirtualKey	| The virtual key/event code.
@parm   KEY_STATE_FLAGS	| KeyEvent		| The KeyStateDownFlag set or cleared.

@xref
	<tab><f KeybdDriverInitialize><nl>
	<tab><t KEY_STATE_FLAGS>

@comm The keyboard driver does not implement this function.  This is the
signature of the function which is passed in to the driver by the user
input system when it calls <f KeybdDriverInitialize>.  The driver should
remember it and call it whenever there is a keyboard event.

@comm The KeyStateDownFlag in the KeyEvent parameter should be set for a
key down event and clear for a key up event.  All other bits must be 0.

@comm The VirtualKey argument has more than just the virtual key
information.  See keybddr.h for a description of the layout of the
information in this argument.

@comm When a keyboard is connected or disconnected, an event must be
signalled with the appropriate connect or disconnect event code set in the
VirtualKey argument.
