curs_deleteln(3X)curs_deleteln(3X)NAME
deleteln, wdeleteln, insdelln, winsdelln, insertln, win-
sertln - 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
The deleteln and wdeleteln routines delete the line under
the cursor in the window; 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.
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.
The insertln and winsertln routines, insert a blank line
above the current line and the bottom line is lost.
RETURN VALUE
All routines return the integer ERR upon failure and an OK
(SVr4 specifies only "an integer value other than ERR")
upon successful completion.
PORTABILITY
These functions are described in the XSI Curses standard,
Issue 4. The standard specifies that they return ERR on
failure, but specifies no error conditions.
NOTES
Note that all but winsdelln may be macros.
These routines do not require a hardware line delete or
insert feature in the terminal. In fact, they won't use
hardware line delete/insert unless idlok(..., TRUE) has
been set on the current window.
