curs_deleteln(3X)                                         curs_deleteln(3X)


   NAME
         cursdeleteln:  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 insertln 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.
