The refresh() and wrefresh() routines copy stdscr and
win, respectively, to the terminal screen. These
routines call the wnoutrefresh() routine to copy the
specified window to curscr and the doupdate() routine
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() is
enabled (in which case, the cursor is placed in a
position that CURSES finds convenient).
When outputting several windows at once, it is often
more efficient to call the wnoutrefresh() and doupdate()
routines directly. A call to wnoutrefresh()for each window first, followed by only one call to doupdate() 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 global variable curscr, the screen is immediately cleared and repainted from scratch.
