CURSES_DELETELN(3)					   BSD Library Functions Manual 					CURSES_DELETELN(3)

NAME

     curses_deleteln, deleteln, wdeleteln -- curses delete single line routines

LIBRARY

     Curses Library (libcurses, -lcurses)

SYNOPSIS

     #include <curses.h>

     int
     deleteln(void);

     int
     wdeleteln(WINDOW *win);

DESCRIPTION

     These functions delete a single line from stdscr or from the specified window.

     The deleteln() function deletes the screen line containing the cursor in the stdscr.  The wdeleteln() function is the same as the deleteln()
     function, excepting that the line is deleted from the window specified by win.

     All lines following the deleted line are moved up one line toward the cursor.  The last line of the window is cleared.  The cursor position
     is unchanged.

     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 up and the bottom line of the scrolling
     region cleared.

     The functions deleteln() and wdeleteln(win) are equivalent to winsdelln(stdscr, -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.

SEE ALSO

     curses_insdelln(3), curses_insertln(3), curses_scroll(3)

STANDARDS

     The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification.

HISTORY

     The Curses package appeared in 4.0BSD.

NAME

     curses_insdelln, insdelln, winsdelln -- curses insert or delete lines routines

LIBRARY

     Curses Library (libcurses, -lcurses)

SYNOPSIS

     #include <curses.h>

     int
     insdelln(int n);

     int
     winsdelln(WINDOW *win, int n);

DESCRIPTION

     These functions insert or delete lines on stdscr or on the specified window.

     If insdelln() is called with a positive number in n, then the specified number of lines are inserted before the current line on stdscr.  The
     last n lines of the screen are no longer displayed.  If n is negative, then n lines are deleted from stdscr, starting at the current line.
     The last n lines of stdscr are cleared.

     The winsdelln() function is the same as the insdelln() function, excepting that lines are inserted or deleted from the window specified by
     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 affected.

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.
