 *  Description:    This header file acts as an interface to the physical
 *                  floppy access functions for the dskimage utility.
 *
 *  Comments:       This is a Win32 interface, used by dskimage.c.  If
 *                  physical disk access is permitted on platforms other
 *                  than NT, the module containing these services should
 *                  export this interface.
