Manual Reference Pages - INSDELLN (3)
winsertln - delete and insert lines in a curses window
int wdeleteln(WINDOW *win);
int insdelln(int n);
int winsdelln(WINDOW *win, int n);
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
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
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.
