CURSES_INSERTLN(3)      NetBSD Library Functions Manual     CURSES_INSERTLN(3)


NAME

     curses_insertln, insertln, winsertln -- curses insert single line rou-
     tines


LIBRARY

     Curses Library (libcurses, -lcurses)


SYNOPSIS

     #include <curses.h>

     int
     insertln(void);

     int
     winsertln(WINDOW *win);


DESCRIPTION

     These functions insert a single line on stdscr or on the specified win-
     dow.

     The insertln() function inserts a blank line before the current line on
     stdscr.  The current line and all lines below are moved down one line
     away from the cursor and the bottom line of the window is lost.

     The winsertln() function is the same as the insertln() function, except-
     ing that the line is inserted on the window win.

     If a scrolling region has been set with the setscrreg() or wsetscrreg()
     functions and the current cursor position is inside the scrolling region,
     then only the lines from the current line to the bottom of the scrolling
     region are moved down and the bottom line of the scrolling region lost.

     The functions insertln() and winsertln(win) are equivalent to insdelln(1)
     and winsdelln(win, 1), respectively.


RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.
     The functions that return an int will return one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.
