REDRAWWIN(3XCURSES)REDRAWWIN(3XCURSES)NAME
redrawwin, wredrawln - redraw screen or portion of screen
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#include <curses.h>
int redrawwin(WINDOW *win);
int wredrawln(WINDOW *win, int beg_line, int num_lines);
PARAMETERS
win
Is a pointer to the window in which to redraw.
beg_line
Is the first line to redraw.
num_lines
Is the number of lines to redraw.
DESCRIPTION
The redrawwin() and wredrawln() functions force portions of a window to
be redrawn to the terminal when the next refresh operation is per‐
formed.
The redrawwin() function forces the entire window win to be redrawn,
while the wredrawln() function forces only num_lines lines starting
with beg_line to be redrawn. Normally, refresh operations use optimiza‐
tion methods to reduce the actual amount of the screen to redraw based
on the current screen contents. These functions tell the refresh
operations not to attempt any optimization when redrawing the indi‐
cated areas.
These functions are useful when the data that exists on the screen is
believed to be corrupt and for applications such as screen editors that
redraw portions of the screen.
RETURN VALUES
On success, these functions return OK. Otherwise, they return ERR.
ERRORS
None.
