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.

STANDARDS
