NAME
       curs_deleteln:  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
       With the deleteln and wdeleteln routines, the line under the cursor
       in the window is deleted; 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.  (This does not imply use of a hardware
       delete line feature.)

       With 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.

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

RETURN VALUE
       All routines return the integer ERR upon failure and an integer value
       other than ERR upon successful completion.

NOTES
       The header file <curses.h> automatically includes the header files
       <stdio.h> and <unctrl.h>.

       Note that all but winsdelln may be a macros.
