winsertln
curs_deleteln(3X)curs_deleteln(3X)NAME
deleteln, wdeleteln, insdelln, winsdelln, insertln, winsertln - 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 comple-
tion.
X/Open defines no error conditions. In this implementation, if the window parameter is null, an error is returned.
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 will not use hardware line
delete/insert unless idlok(..., TRUE) has been set on the current window.
