curs_delln(3X)

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 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.
