CURSDELLN(3X-SVR4) RISC/os Reference Manual  CURSDELLN(3X-SVR4)



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 macros.
