NAME

     deleteln, wdeleteln, insdelln, winsdelln, insertln, win-
     sertln - 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 completion.

     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 won't use
     hardware line delete/insert unless idlok(..., TRUE) has been
     set on the current window.
