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

       #include <ncurses.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);

       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

       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 insertln routines, insert a blank line above the cur‐
       rent line and the bottom line is lost.

       All routines return the integer ERR upon failure and an OK (SVr4 speci‐
       fies  only  "an	integer value other than ERR") upon successful comple‐

       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.

       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.
