curs_deleteln(3X)                UNIX System V                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.
