43*7c478bd9Sstevel@tonic-gate  * This routine is used by initialization routines. It sets it up
44*7c478bd9Sstevel@tonic-gate  * such that a line is removed from the user's screen by initscr. This
45*7c478bd9Sstevel@tonic-gate  * function must be called BEFORE initscr. It works by leaving a cookie
46*7c478bd9Sstevel@tonic-gate  * which tells initscr to reduce the size of stdscr by one for each line
47*7c478bd9Sstevel@tonic-gate  * ripped off. This routine has been generalized so that other applications
48*7c478bd9Sstevel@tonic-gate  * can make use of it in a straightforward manner.
