CURSES_INSDEL(3)           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.
