45*0Sstevel@tonic-gate * This routine indicates to curses that a screen line is garbaged and
46*0Sstevel@tonic-gate * should be thrown away before having anything written over the top of it.
47*0Sstevel@tonic-gate * It could be used for programs such as editors which want a command to
48*0Sstevel@tonic-gate * redraw just a single line. Such a command could be used in cases where
49*0Sstevel@tonic-gate * there is a noisy line and redrawing the entire screen would be subject
50*0Sstevel@tonic-gate * to even more noise. Just redrawing the single line gives some semblance
51*0Sstevel@tonic-gate * of hope that it would show up unblemished.
