This function is a prototype of the callback function passed to the KeybdDriverInitializefunction.

void KeybdEventCallback(


Specifies code for the virtual key or event.
Specifies the KeyStateDownFlagbeing set or cleared.


The keyboard driver does not implement this function. This is the prototype of this function passed into the driver by the user input system when it calls the KeybdDriverInitializefunction. The driver calls the callback function whenever there is a keyboard event.

The KeyStateDownFlag field in the KeyEventparameter is set for a key-down event and clear for a key-up event. All other bits must be 0. The VirtualKeyparameter has more than just the virtual key information. See the Keybddr.h header file for a description of the information in this parameter.

When a keyboard is connected or disconnected, an event must be signaled with the appropriate connect-event code or disconnect-event code set in the VirtualKeyparameter.
