Discards and replaces a number of lines in a window.
Curses Library (libcurses.a)
The garbagedlines subroutine discards and replaces lines in a window. The Begline parameter specifies the beginning line number and the Numlines parameter specifies the number of lines to discard. Curses discards and replaces the specified lines before adding more data.
Uses this subroutine for applications that need to redraw a line that is garbled. Lines may become garbled as the result of noisy communication lines. Instead of refreshing the entire display, use the garbagedlines subroutine to refresh a portion of the display and to avoid even more communication noise.
