#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 ); LIBRARY
Curses Library (libcurses) STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: deleteln, wdeleteln, insdelln, winsdelln, insertln, winsertln: XCURSES4.2 Refer to the standards(5) reference page for more information about industry standards and associated tags. DESCRIPTION
The deleteln and wdeleteln routines do the following: Delete the line under the cursor in the current or specified window Move all lines below the current line up one line Clear the bottom line of the window These routines do not change the cursor position. (This does not imply use of a hardware delete line feature.) The insdelln and winsdelln routines do the following: For positive n, insert n lines into the current or 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. These routines do not change the current cursor position. The insertln and insertln routines insert a blank line above the current line. The bottom line is lost. (This does not imply use of a hard- ware insert line feature.) NOTES
The header file <curses.h> automatically includes the header file <stdio.h>. Note that all routines except winsdelln may be macros. RETURN VALUES
All routines return ERR upon failure and OK upon successful completion. SEE ALSO
