curs_deleteln(3)                                 curs_deleteln(3)

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

       #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);

       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 insertln routines, insert  a  blank  line
       above the current line and the bottom line is lost.

       All routines return the integer ERR upon failure and an OK
       (SVr4 specifies only "an integer value  other  than  ERR")
       upon successful completion.

       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.
