curs_deleteln(3X)curs_deleteln(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.
