curs_deleteln(3X)					     curs_deleteln(3X)

NAME
       deleteln,  wdeleteln, insdelln, winsdelln, insertln, winsertln -	delete
       and insert lines	in a curses window

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);

DESCRIPTION
       The deleteln and	wdeleteln routines delete the line under the cursor in
       the  window;  all  lines	 below the current line	are moved up one line.
       The bottom line of the window is	cleared.  The cursor position does not
       change.

       The  insdelln  and  winsdelln  routines,	for positive n,	insert n lines
       into the	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.	 The current cursor position remains the same.

       The  insertln and winsertln routines insert a blank line	above the cur-
       rent line and the bottom	line is	lost.

RETURN VALUE
       All routines return the integer ERR upon	failure	and an OK (SVr4	speci-
       fies  only  "an	integer	value other than ERR") upon successful comple-
       tion.

       X/Open defines no error conditions.  In	this  implementation,  if  the
       window parameter	is null, an error is returned.

PORTABILITY
       These functions are described in	the XSI	Curses standard, Issue 4.  The
       standard	specifies that they return ERR on failure,  but	 specifies  no
       error conditions.

NOTES
       Note that all but winsdelln may be macros.

       These  routines do not require a	hardware line delete or	insert feature
       in  the	terminal.   In	fact,  they  will  not	 use   hardware	  line
       delete/insert  unless idlok(...,	TRUE) has been set on the current win-
       dow.
