NAME    [Toc]    [Back]

     curs_deleteln:  deleteln, wdeleteln, insdelln, winsdelln, insertln,
     winsertln - delete	and insert lines in a curses window

SYNOPSIS    [Toc]    [Back]

     #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    [Toc]    [Back]

     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    [Toc]    [Back]

     All routines return the integer ERR upon failure and an integer value
     other than	ERR upon successful completion.

NOTES    [Toc]    [Back]

     The header	file <curses.h>	automatically includes the header files
     <stdio.h> and <unctrl.h>.

     Note that all but winsdelln may be	a macros.
