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 spec-
       ifies  only "an integer value other than ERR") upon successful comple-
       tion.

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 won’t use hardware line delete/insert
       unless idlok(..., TRUE) has been set on the current window.
