curs_deleteln(3X) curs_deleteln(3X)
deleteln, wdeleteln, insdelln, winsdelln, insertln, winsertln -
delete and insert lines in a curses window
#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);
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.
All routines return the integer ERR upon failure and an OK (SVr4
specifies only "an integer value other than ERR") upon successful
completion.
X/Open defines no error conditions. In this implementation, if
the window parameter is null, an error is returned.
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.
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 will not use hardware
line delete/insert unless idlok(..., TRUE) has been set on the
current window.
