NAME
redrawwin, wredrawln - redraw screen or portion of screen
SYNOPSIS

cc [ flag... ] file... -I /usr/xpg4/include  -L  /usr/xpg4/lib \e
 -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 performed.

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 optimization 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 indicated 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.
