curs_deleteln(3)

NAME
deleteln, wdeleteln, insdelln, winsdelln, insertln, winsertln - delete and insert lines in a ncurses window

SYNOPSIS
#include <ncurses.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 insertln 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 integer value other than ERR upon successful completion.

NOTES
Note that all but winsdelln may be a 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.
