CURSES_INSDEL(3)		   BSD Library Functions Manual 		 CURSES_INSDEL(3)

     curses_insdelln, insdelln, winsdelln -- curses insert or delete lines routines

     Curses Library (libcurses, -lcurses)

     #include <curses.h>

     insdelln(int n);

     winsdelln(WINDOW *win, int n);

     These functions insert or delete lines on stdscr or on the specified window.

     If insdelln() is called with a positive number in n, then the specified number of lines are
     inserted before the current line on stdscr.  The last n lines of the screen are no longer
     displayed.  If n is negative, then n lines are deleted from stdscr, starting at the current
     line.  The last n lines of stdscr are cleared.

     The winsdelln() function is the same as the insdelln() function, excepting that lines are
     inserted or deleted from the window specified by win.

     If a scrolling region has been set with the setscrreg() or wsetscrreg() functions and the
     current cursor position is inside the scrolling region, then only the lines from the current
     line to the bottom of the scrolling region are affected.

     Functions returning pointers will return NULL if an error is detected.  The functions that
     return an int will return one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.

     curses_deleteln(3), curses_insertln(3), curses_scroll(3)

     The NetBSD Curses library complies with the X/Open Curses specification, part of the Single
     Unix Specification.

     The Curses package appeared in 4.0BSD.
