45*0Sstevel@tonic-gate * This routine is used by initialization routines. It sets it up
46*0Sstevel@tonic-gate * such that a line is removed from the user's screen by initscr. This
47*0Sstevel@tonic-gate * function must be called BEFORE initscr. It works by leaving a cookie
48*0Sstevel@tonic-gate * which tells initscr to reduce the size of stdscr by one for each line
49*0Sstevel@tonic-gate * ripped off. This routine has been generalized so that other applications
50*0Sstevel@tonic-gate * can make use of it in a straightforward manner.
