redrawwin(3XCURSES)					  X/Open Curses Library Functions				       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 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.
