NAME
  curs_deleteln, deleteln, wdeleteln, insdelln, winsdelln, insertln,
  winsertln - Delete or insert lines in a Curses window

LIBRARY
  Curses Library (libcurses.a, libcurses.so)

SYNOPSIS
  #include <curses.h>

  int deleteln(void);
  int wdeleteln(WINDOW *win);
  int insdelln(int n);
  int winsdelln(WINDOW *win, int n);
  int insertln(void);
  int winsertln(WINDOW *win);

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows: deleteln, wdeleteln, insertln, winsertln:	 XPG4, XPG4-UNIX

  insdelln, winsdelln: XPG4-UNIX

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

DESCRIPTION
  The deleteln and wdeleteln routines do the following:

    ·  Delete the line under the cursor in the current or specified window

    ·  Move all lines below the current line up one line

    ·  Clear the bottom line of the window

  These routines do not change the cursor position.  (This does not imply use
  of a hardware delete line feature.)

  The insdelln and winsdelln routines do the following:

    ·  For positive n, insert n lines into the current or specified window
       above the current line

       The n bottom lines are lost.

    ·  For negative n, delete n lines (starting with the one under the
       cursor), and move the remaining lines up

       The bottom n lines are cleared.

  These routines do not change the current cursor position.

  The insertln and insertln routines insert a blank line above the current
  line.	 The bottom line is lost.  (This does not imply use of a hardware
  insert line feature.)

NOTES
  The header file curses.h automatically includes the header file stdio.h.

  Note that all routines except winsdelln may be macros.

RETURN VALUES
  All routines return ERR upon failure and OK upon successful completion.
