doupdate(3XCURSES)	X/Open Curses Library Functions	    doupdate(3XCURSES)

NAME
       doupdate, refresh, wnoutrefresh, wrefresh - refresh windows and lines

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 doupdate(void);

       int refresh(void);

       int wnoutrefresh(WINDOW *win);

       int wrefresh(WINDOW *win);

DESCRIPTION
       The  refresh()  and  wrefresh() functions copy stdscr and  win, respec‐
       tively, to the terminal screen. These functions call the wnoutrefresh()
       function	 to  copy  the	specified  window to curscr and the doupdate()
       function to do the  actual update.  The physical cursor	is  mapped  to
       the  same  position as the logical cursor of  the last window to update
       curscr unless leaveok(3XCURSES) is enabled  (in which case, the	cursor
       is placed in a position that X/Open Curses finds	 convenient).

       When  outputting several windows at once, it is often more efficient to
       call the wnoutrefresh() and doupdate() functions directly.  A  call  to
       wnoutrefresh()  for  each  window,  followed by only one call  to doup‐
       date() to update the screen, results in one  burst  of  output,	 fewer
       characters sent, and less CPU time used.

       If  the win parameter to wrefresh() is the global variable  curscr, the
       screen is immediately cleared and repainted from scratch.

       For details on how  the	wnoutrefresh()	function  handles  overlapping
       windows	with  broad glyphs, see the Overlapping Windows section of the
       curses(3XCURSES) reference manual page.

PARAMETERS
       win    Is a pointer to the window in which to refresh.

RETURN VALUES
       On success, these functions return OK. Otherwise, they return ERR.

ERRORS
       None.
