 *
 * Modification History:
 *
 * 14-Jul-88  -- vasudev (Vasudev K. Bhandarkar)
 *       
 *      Removed sched_flags from the SM_Info data structure and
 *      deleted spurious irrelevant comments.
 *
 * 14-May-87  -- fred (Fred Canter)
 *	Added QD_KERN_UNLOOP ioctl definition. This is a duplicate of
 *	QIOKERNUNLOOP, but is needed!
 *
 * 19-Mar-87  -- fred (Fred Canter)
 *	Added screen saver ioctls.
 *
 * 30-Aug-86  -- rafiey (Ali Rafieymehr)
 *	Changes for smscreen (console message window) support.
 *
 *  5-Aug-86  -- rafiey (Ali Rafieymehr)
 *	Minor change for real VAXstar bitmap graphics driver.
 *
 * 18-Jun-86  -- rafiey (Ali Rafieymehr)
 *	Created this header file for the VAXstar monochrome display driver.
 *	Derived from qvioctl.h.
