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

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

LIBRARY
     Curses Library (libcurses, -lcurses)

SYNOPSIS
     #include <curses.h>

     int
     insdelln(int n);

     int
     winsdelln(WINDOW *win, int n);

DESCRIPTION
     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.

RETURN VALUES
     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.
