curs_deleteln(3ocurses)

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

Synopsis

cc [flag . . .] file -locurses [library . . .]

#include <ocurses.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 values

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