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

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

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 a 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.
