HFILE hDevice;    /* device handle                     */
 
The KBD_GETCODEPAGEID function retrieves the identifier of the code page
being used by the current logical keyboard.

           identifier.
 
hDevice    Identifies the keyboard that receives the device-control
           function. The handle must have been created previously by using
           the DosOpen function.

an error occurs.
 
Comments
